Description

The present invention relates to a surveying system. The present invention also relates to a surveying method using this surveying system and a surveying program that can implement this surveying system.

Surveying is an extremely important technology that forms the basis of construction work and transactions. There are various types of surveying, one of which is current status surveying, which measures existing structures (buildings, fences, telephone poles, roads, railroad tracks, etc.) and topography. Conventional current state surveying was usually carried out by two or more people using a total station and a surveying pole to which a surveying prism was attached. In other words, one worker holds the surveying pole upright above the surveyed area, and another worker operates the total station to direct the laser beam into the surveying prism. The position information of the surveying prism was obtained by irradiating it with the beam. However, this method requires two or more people to perform the work at all times, resulting in an increase in labor costs.

Perhaps in view of this situation, FIG. 1 etc. of Patent Document 1 describes that the observation equipment 4 (total station, etc.) is controlled using the surveying terminal device 1 that can be operated at the hand of the worker U. ing. While holding the target 3 to which the surveying prism is attached, the worker U presses the playback button on the earphone 2 with a remote control function connected to the earphone jack of the surveying terminal device 1 to perform observation using the observation device 4. can be done. The observed survey points are displayed on the CAD drawing displayed on the display screen 151 of the survey terminal device 1, as described in FIG. 4 of the same document. Accordingly, it is said that even one worker U can easily carry out the survey.

Japanese Patent Application Publication No. 2016-136100

However, in the method described in Patent Document 1, after the survey of one survey point is completed, the next survey is carried out while comparing the CAD drawing displayed on the display screen 151 of the surveying terminal device 1 with the survey target area. There was a problem that it was troublesome to have to search for the desired location. In particular, in the method of the same document, as shown in Figure 1 of the same document, the worker U performs the survey with both hands occupied by the target 3 and the earphones 2, so when trying to check the CAD drawing, In this case, it is necessary to let go of the target 3 or the earphones 2 and lift the surveying terminal device 1. When the next survey point is found, let go of the surveying terminal device 1 again and lift the target 3 or the earphones 2. It was very complicated because it had to be recovered.

The present invention has been made to solve the above problems, and provides a surveying system that can be operated by one person and is simple to operate. Another object of the present invention is to provide a surveying method using this surveying system. Furthermore, it is another object of the present invention to provide a surveying program that can realize this surveying system.

This can be realized by a surveying program that can function as a.

Here, the real space in the case where "the user is allowed to view the virtual space in a state where it is overlapped with the real space" may be the real space that the user directly sees, or an image of the real space taken with a camera, etc. etc. may be used. Furthermore, the term "head" in this specification refers to a portion above the user's neck. Therefore, the specific mounting location of the "head-mounted display device" is not limited as long as it can be mounted anywhere above the user's neck. A "head-mounted display device" may be, for example, something that can be worn by putting it over the head, as shown in Figure 1 below, or something that can be worn by hanging it on the ear like a pair of glasses. It may be something that can be worn.

The procedure for conducting a survey using the above survey system is as follows. First, the user wears a head-mounted display device so that the user can visually recognize the virtual space in a state that overlaps with the real space. Next, a predetermined operation is performed while the contact portion of the surveying tool is brought into contact with the surveyed location. Then, coordinate information of the surveyed location is acquired, and a predetermined object is generated at a location corresponding to the surveyed location in the virtual space. As a result, the user can visually recognize the surveyed locations where the survey has been completed and the surveyed locations that have not yet been completed, as if he or she had marked (drawn) the surveyed location in real space. can be intuitively distinguished. Therefore, after the surveying of one surveyed location is completed, the surveying of the next surveyed location can be started smoothly. In this way, the surveying system of the present invention allows one person to perform surveying work and is simple to operate.

In the above surveying system, the tool position acquisition means is not particularly limited in its specific position acquisition method. In some embodiments of the surveying system, position information of the head-mounted display is obtained based on information obtained by optical methods using a reflective member attached to the head-mounted display and a total station. and a relative position acquisition means capable of acquiring relative position information of the surveying tool with respect to the head-mounted display device. The position information of the surveying tool can be acquired based on the position information of the head-mounted display device acquired by the acquisition means and the relative position information acquired by the relative position acquisition means. Thereby, the position information of the surveying tool can be acquired with high accuracy, and the configuration of the surveying tool can be made simple, so that the surveying tool can be made lightweight and compact.

In this case, the display device position acquisition means may be further configured to operate in a TS mode in which the position information of the head-mounted display device is acquired based on information obtained by an optical method using a reflective member and a total station, and in a GNSS mode. (Global Navigation Satellite System) It is possible to switch between the mode and the GNSS mode in which position information of the head-mounted display device is acquired based on information obtained by RTK (Real Time Kinematic) positioning using signals. . As a result, for example, in urban areas where it is easy to install a total station and high survey accuracy is required, the TS mode can be used to acquire position information of head-mounted display devices and surveying tools with high accuracy (i.e., with high accuracy). In mountainous areas where it is difficult to install a total station and high survey accuracy is not required, the GNSS mode can be used to conduct a survey without installing a total station.

Some embodiments of the surveying system may further include a connecting line generating means capable of generating a connecting line connecting one object and another object in the virtual space based on a user's operation. can. This makes it easier to understand the relationships between multiple objects. Furthermore, it is also possible to easily record the relationships between a plurality of surveyed locations.

By the way, the locations to be surveyed in the current state survey may include locations that are difficult to contact with the contact portion of the surveying tool, such as the roof of a neighbor's house. For this reason, in some embodiments of the surveying system, the surveying tool is further provided with a tool position acquisition means capable of acquiring position information (information regarding orientation, information regarding inclination, etc.) of the surveying tool. An optical distance measuring means having a laser beam emitting section and a laser beam entering section is provided, and the coordinate information acquiring means includes position information acquired by the tool position acquiring means, posture information acquired by the tool posture acquiring means, and the optical distance measuring means. It is also possible to obtain the coordinates of the surveyed location based on the distance information obtained. Thereby, as will be explained in detail later, it is also possible to survey locations where it is difficult to bring the contact portion into contact.

In some embodiments of the surveying system, the tool position acquisition means acquires position information of the surveying tool based on information obtained by an optical method using a reflective member attached to the surveying tool and a total station. shall be able to obtain. Thereby, the position information of the surveying tool can be acquired with high accuracy, and the surveying accuracy can be improved. Further, as will be described later, the configuration of the head-mounted display device can be made simple.

As described above, the present invention makes it possible to provide a surveying system that allows one person to perform surveying work and is simple to operate. It also becomes possible to provide a surveying method using this surveying system. Furthermore, it is also possible to provide a surveying program that can implement this surveying system.

FIG. 2 is a diagram illustrating an example of a user's field of view, and is a diagram illustrating how a surveyed point _P1 is surveyed. It is a diagram showing an example of the user's field of view, and is a diagram showing how a connecting line L ₁₂ connecting the surveyed point P ₁ and the surveyed point P ₂ is displayed. It is a front view of the surveying tool in other embodiments.

Preferred embodiments of the present invention will be described in more detail with reference to the drawings. However, the technical scope of the present invention is not limited to the embodiments described below.

1. Overview FIG. 1 is a diagram showing how the surveying system of this embodiment is used. FIG. 2 is a block diagram showing an example of the network environment of the surveying system. As shown in FIG. 1, the surveying system of this embodiment includes a head-mounted display device 10, a surveying tool 20, and a control section 30, and is used together with a total station T.

The head-mounted display device 10 is used by being worn on the head of a user U, as shown in the enlarged view of FIG. The head-mounted display device 10 supports a display unit 11 for allowing a user U to view a virtual space to be described later, a reflecting member 12 for reflecting laser light emitted from a total station T, and a reflecting member 12. It has a reflective member support part 13 for the purpose of the transmission, and an RTK-GNSS antenna (not shown). The head-mounted display device 10 also includes a posture detection means 14 that can detect the posture (azimuth, tilt, rotation, etc.) of the head-mounted display device 10, as shown in FIG.

A contact portion 21 is provided on the distal end side of the surveying tool 20 for contacting a surveyed location. Further, on the base end side of the surveying tool 20, an optical distance measuring means 22 is provided, which has a laser beam emitting section 22a that can emit a laser beam and a laser beam input section 22a that can input a laser beam. It is being

The control unit 30 is usually realized by an electronic computing device. As shown in FIG. 2, the control unit 30 includes a virtual space definition means 31, a virtual space information provision means 32, a display device position acquisition means 33, a tool position acquisition means 34, a tool position acquisition means 35, and a coordinate It includes an information acquisition means 36, an object generation means 37, a connecting line generation means 38, and a storage means 39. The head-mounted display device 10 and the surveying tool 20, the head-mounted display device 10 and the control unit 30, the head-mounted display device 10 and the total station T, the surveying tool 20 and the control unit 30, and the total station T. The control unit 30 is connected (wireless or wired, direct connection or indirect connection) in a state where data communication is possible.

The virtual space definition means 31 of the control unit 30 can define a virtual space corresponding to the real space. By wearing the head-mounted display device 10, the user U can visually recognize this virtual space in a state overlapping with the real space (in a state in which the virtual space and the real space are three-dimensionally superimposed). can. The position information of the head-mounted display device 10 is acquired in real time by an optical method using the reflective member 12 attached to the head-mounted display device 10 and the total station T. Posture information (direction, inclination, etc.) of the wearable display device 10 is detected in real time by a posture detection means 14 provided in the head-mounted display device 10. As a result, when the user U moves, rotates or tilts the head, the way the virtual space is viewed changes according to the movement. Therefore, the user U can feel as if he or she is in a space where virtual space and real space are fused.

2. Surveying method The following describes the procedure for conducting a survey using this surveying system. In the surveying system of this embodiment, contact surveying is performed using the contact part 21 (FIG. 1) of the surveying tool 20, and non-contact surveying is performed using the optical distance measuring means 22 of the surveying tool 20. You can do both.

2.1 Contact Surveying Contact surveying is a method of conducting a survey by bringing the contact part 21 of the surveying tool 20 into contact with a surveyed location. Hereinafter, the procedure of contact surveying will be described using as an example the case where surveyed points (surveyed locations) P ₁ , P ₂ , and P ₃ shown in FIG. 1 are surveyed. FIG. 3 is a diagram showing an example of the field of view of the user U, and is a diagram showing how the surveyed point _P1 is surveyed. Figure 3(a) shows the state before surveying point _P1 , Figure 3(b) shows the state before surveying point _P1 , and Figure 3(c) shows the state before surveying point P1. Each figure shows the state in which survey _{No. 1} has been completed. FIG. 4 is a diagram illustrating an example of the field of view of the user U, and is a diagram illustrating how a connecting line L ₁₂ connecting the surveyed point P ₁ and the surveyed point P ₂ is displayed. FIG. 4(a) shows the state before the connecting line _L12 is displayed, and FIG. 4(b) shows the state after the connecting line _L12 is displayed. In FIG. 3, for convenience of illustration, the hand and arm of the user U holding the surveying tool 20 are omitted.

User U first installs total station T. Subsequently, the head-mounted display device 10 is worn so that the virtual space and the real space can be viewed in an overlapping manner, as shown in FIG. 3(a). Thereafter, as shown in FIG. 3(b), with the contact portion 21 of the surveying tool 20 in contact with the point _P1 to be surveyed, an instruction is given to acquire the coordinates of the point _P1 to be surveyed. A predetermined operation (hereinafter sometimes referred to as "coordinate acquisition operation") is performed to obtain the coordinates. Then, the coordinate information of the surveyed point P ₁ is acquired based on the position information of the surveying tool 20 (described in detail later), and as shown in FIG. 3(c), the coordinate information of the surveyed point P ₁ in the virtual space is acquired. Object _O1 is displayed at a location corresponding to (overlapping with) . Thereby, the user U can intuitively sense that the surveyed point _P1 has been surveyed. In addition, if you accidentally survey a position that deviates from the surveyed point _P1 , the object _O1 will be displayed at a position that deviates from the surveyed point _P1 , so you can check the surveying deviation at a glance. It can be recognized and re-measured immediately.

When the survey points P ₂ and P ₃ are surveyed one after another using the same procedure, multiple objects O ₁ , O ₂ , and O ₃ are displayed in the virtual space as shown in FIG. 4(a). Become so. However, if the plurality of objects O ₁ , O ₂ , O ₃ are only displayed independently, it may be difficult to understand the relationship between the objects O ₁ , O ₂ , O ₃ . In this regard, in this embodiment, when the user U performs a predetermined operation (hereinafter referred to as "connection line display operation"), one object O ₁ and another object O ₂ are displayed as shown in FIG. 4(b). A connecting line _L12 connecting the two can be displayed in the virtual space. As a result, it can be determined that, for example, the surveyed point P ₁ corresponding to the object O ₁ and the surveyed point P ₂ corresponding to the object O ₂ are adjacent surveyed points of the same structure in real space. It can be easily demonstrated.

The coordinate information of the surveyed point and the connecting line information regarding the connecting line obtained through the above procedure are stored in the storage means 39 of the control unit 30. The control unit 30 may include a drawing output means (not shown) for outputting drawing data (for example, three-dimensional CAD data, two-dimensional CAD data, etc.) based on the coordinate information and connection line information. . This allows drawing data to be easily created.

In this way, by using the surveying system of this embodiment, even one person can perform surveying work, and highly accurate surveying can be achieved with simple operations.

In contact surveying, by appropriately bringing the contact portion 21 into contact with the location to be surveyed, it is possible to perform surveying with high accuracy. In other words, if a survey is performed while the contact portion 21 is not in contact with the location to be surveyed, it may be difficult to improve the survey accuracy. Therefore, the contact portion 21 can be provided with contact detection means that can detect whether or not the contact portion 21 is in contact with the surveyed location. Thereby, for example, it is possible to prevent surveying from being performed when the contact portion 21 is not in contact with the location to be surveyed, or to issue a warning to the user U. Therefore, it is possible to easily improve surveying accuracy. As the contact detection means, for example, a contact switch, a contact sensor, an optical sensor, etc. can be used.

The specific operation method for the coordinate acquisition operation for acquiring the coordinates of the surveyed location is not particularly limited. The coordinate acquisition operation can be performed, for example, by voice input, gaze input, or input via an input device (for example, input via a button or touch panel provided on the surveying tool 20 or the head-mounted display device 10, etc.). ) etc. For example, when a contact switch is provided on the contact part 21 as the above-mentioned contact detection means, the coordinate acquisition operation described above can be performed by pressing the contact switch (that is, pressing the contact part 21 against the surveyed location). You may also do so.

There is no limit to the timing of the connection line display operation. The connection line display operation can be performed, for example, when the surveying of one surveyed point _P1 has been completed and another surveyed point _P2 is to be surveyed, or when the surveying of another surveyed point _P2 is to be carried out. This can be done while the survey is being carried out or after the surveying of the other surveyed point _P2 is completed. The specific method of displaying the connecting line is not particularly limited, and can be performed by voice input, line of sight input, input via an input device, or the like. The input method for the coordinate acquisition operation and the input method for the connection line display operation may be the same or different.

The object is not limited in its specific form (shape, color, pattern, etc.; the same applies hereinafter). When a plurality of objects are generated (displayed), the plurality of objects may have substantially the same form or may have different forms from each other. The form of the object may be determined based on the properties of the corresponding surveyed location. In this embodiment, the objects O ₁ , O ₂ , and O ₃ are approximately spherical. The form of the bond line is also not particularly limited. The connecting line may be approximately straight or may be curved based on user U's operation. Furthermore, the line type of the bonding line is not limited. The connecting line may be a continuous line (solid line) or an interrupted line (for example, a dotted line, a broken line, a dot-dashed line, etc.), and the line type can be determined based on the user U's operation. Good too.

2.2 Non-contact surveying Non-contact surveying is a method of surveying using the optical distance measuring means 22 of the surveying tool 20 (enlarged view of FIG. 1). This method is particularly useful when it is desired to survey a location to be surveyed that is difficult to contact with the contact portion 21 of the surveying tool 20, such as the eaves of a neighboring house's roof.

The procedure for non-contact surveying is as follows. The user U first installs the total station T and wears the head-mounted display device 10 as in the contact survey. Subsequently, the optical distance measuring means 22 of the surveying tool 20 is used to obtain distance information to the surveyed location. That is, the laser beam emitting section 22a is directed toward the surveyed location, and the laser beam is emitted from the laser beam emitting section 22a to irradiate the surveyed location. A part of the irradiated laser light is reflected at the measurement point and enters the laser light incidence section 22a. Distance information to the surveyed location is acquired based on the information on the emitted laser beam and the information on the incident laser beam. When the distance information is acquired, the coordinate information of the surveyed point is acquired based on the distance information and the position information and posture information of the surveying tool 20 (details will be explained later). Similarly, a predetermined object is displayed at a location corresponding to the surveyed location in the virtual space. For other procedures, the same ones as for contact surveying can be adopted. In this way, by using the surveying system of the present embodiment, it is possible to survey locations where it is difficult to contact with the contact portion 21 with simple operations.

3. Head-mounted display device The head-mounted display device 10 (FIG. 1) allows the user U to visually recognize the virtual space defined by the virtual space definition means 31 through the display unit 11 in a state that overlaps with the real space. This is a device that can

The specific configuration of the display unit 11 is not limited as long as the virtual space can be viewed by the user U in a state where it overlaps with the real space. The "real space" in this case may be an actual real space or an image obtained by photographing the real space. The display unit 11 may be, for example, a display (image display device) or a hologram forming device. In this embodiment, a transmissive display is used as the display unit 11, and by displaying a predetermined image on the transmissive display, the user U can see the virtual space and the real space seen through the transmissive display. This allows you to view them over and over again.

As the reflecting member 12, a surveying prism is normally used. Among these, it is preferable to use a 360° prism. The mounting location and mounting method of the reflective member 12 are not particularly limited as long as the reflective member 12 is directly or indirectly attached to the head-mounted display device 10 without changing its relative position to the head-mounted display device 10. . In this embodiment, as shown in the enlarged view of FIG. 12 is arranged near the top of user U's head. The reflective member support portion 13 may be shaped like a helmet, for example.

The posture detection means 14 is a means that can detect the posture (azimuth, tilt, rotation, etc.) of the head-mounted display device 10 in real time. The position detecting means 14 can include, for example, a direction detecting means such as an electronic compass, a tilt detecting means such as an acceleration sensor, a rotation speed detecting means such as a gyro sensor, and the like.

4. Surveying Tool The surveying tool 20 in this embodiment has a pen shape as shown in FIG. 1, but the shape of the surveying tool 20 is not particularly limited. Further, in this embodiment, the optical distance measuring means 22 is provided at the proximal end side of the surveying tool 20, but the location where the optical distance measuring means 22 is provided is not particularly limited. It may be on the side.

5. Control unit virtual space definition means 31 is means for defining a virtual space corresponding to real space. The virtual space definition means 31 can define a virtual camera placed in the virtual space. The position and posture (orientation, inclination, etc.) of this virtual camera are determined based on the position information of the head-mounted display device 10 acquired by the display device position acquisition means 33, which will be described later, and the posture detection means 14 of the head-mounted display device 10. The adjustment can be made based on the posture information obtained by.

The virtual space information providing means 32 is a means for providing information on the virtual space defined by the virtual space defining means 31 to the head-mounted display device 10. The specific type of virtual space information provided by the virtual space information providing means 32 is not particularly limited. The virtual space information providing means 32 can, for example, provide the head-mounted display device 10 with information regarding an image captured by the above-described virtual camera.

The display device position acquisition unit 33 (FIG. 2) is a unit that can acquire position information of the head-mounted display device 10 in real time. The display device position acquisition means 33 is not limited in what method it uses to obtain the position information of the head-mounted display device 10. The display device position acquisition means 33 in this embodiment displays the head-mounted display based on information obtained by an optical method using the reflective member 12 attached to the head-mounted display device 10 and the total station T. The location information of the device 10 is acquired. Thereby, position information of the head-mounted display device 10 can be obtained with high accuracy.

By the way, when conducting surveying in a mountainous area, for example, it may be difficult to install the total station T. Therefore, in the surveying system of this embodiment, the head-mounted display device 10 is provided with an RTK-GNSS antenna (not shown), and the display device position acquisition means 33 is connected to the reflective member 12 (FIG. 1) and the total station. The position information of the head-mounted display device 10 is acquired based on the information obtained by an optical method using the TS mode, and the position information obtained by RTK positioning using the GNSS signal obtained from the artificial satellite S. It is possible to switch between the GNSS mode and the GNSS mode in which position information of the head-mounted display device 10 is acquired based on the information. In mountainous areas, surveying can be carried out without installing a total station T by using the GNSS mode.

The tool position acquisition means 34 is means for acquiring position information of the surveying tool 20. The method by which the tool position acquisition means 34 acquires position information is not particularly limited. The tool position acquisition means 34 may acquire position information independently of the display device position acquisition means 33. However, in this case, the system may become complicated and the cost may increase. For this reason, in this embodiment, a relative position acquisition means 34a capable of acquiring relative position information of the surveying tool 20 with respect to the head-mounted display device 10 is further provided, and the tool position acquisition means 34 is connected to the display device. The position information of the surveying tool 20 can be acquired based on the position information of the head-mounted display device 10 acquired by the position acquisition means 33 and the relative position information acquired by the relative position acquisition means 34a. There is. The relative position acquisition means 34a is not limited to a specific method of acquiring relative position information. The relative position acquisition means 34a in this embodiment is a surveying tool based on information obtained using a camera (not shown) or a sensor (not shown) provided in the head-mounted display device 10, or both. It is possible to obtain 20 pieces of relative position information. In this case, the surveying tool 20 may be provided with a marker (not shown) to facilitate acquisition of positional information by a camera or sensor. Markers are usually provided at multiple locations.

There is no particular limitation on which part of the surveying tool 20 the tool position acquisition means 34 acquires position information about. The tool position acquisition means 34 can acquire, for example, position information of the contact portion 21 in the surveying tool 20. Alternatively, the tool position acquisition means 34 can also acquire position information of a location (for example, the base end) of the surveying tool 20 that is away from the contact portion 21 . Alternatively, the tool position acquisition means 34 can acquire position information of a plurality of locations in the surveying tool 20. In this case, the tool position acquisition means 34 can also function as a tool position acquisition means 35, which will be described later.

The tool position acquisition means 35 is means for acquiring position information (for example, azimuth information, inclination angle information, etc.) of the surveying tool 20. The method by which the tool position acquisition means 35 acquires the position information of the surveying tool 20 is not particularly limited. The tool position acquisition means 35 can obtain position information of the surveying tool 20 based on information obtained using a position detection means (not shown) provided in the surveying tool 20, for example. The position detection means can include direction detection means such as an electronic compass, tilt detection means such as an acceleration sensor, rotation speed detection means such as a gyro sensor, and the like. Alternatively, as described above, the posture information of the surveying tool 20 may be obtained by acquiring position information of a plurality of locations on the surveying tool 20 by the tool position acquisition means 34.

When the tool posture acquisition means 35 is provided, a posture information notification means (not shown) that can inform the user U of the posture information of the surveying tool 20 acquired by the tool posture acquisition means 35 can be provided. As a result, for example, when surveying a site to be surveyed that requires higher surveying accuracy, the surveying tool 20 can be adjusted so that it is approximately parallel to the vertical direction while checking the information from the position information notification means. Surveys can be carried out (position information reporting means functions like an electronic bubble tube). The position information notification means can, for example, notify the user U of the information via the display unit 11 of the head-mounted display device 10, or may provide the surveying tool 20 with a display unit (not shown) to display the information. It is also possible to inform the user U of information via the section.

The coordinate information acquisition means 36 stores the position of the surveying tool 20 acquired by the tool position acquisition means 34 when the coordinate acquisition operation is performed with the contact part 21 of the surveying tool 20 in contact with the surveyed location. This is a means for acquiring coordinate information of a surveyed location based on the information. The coordinate information acquisition means 36 may acquire the position information (coordinate values) of the surveying tool 20 acquired by the tool position acquisition means 34 as it is as coordinate information of the surveyed location, or The coordinate information of the surveyed location may be obtained by performing a predetermined offset from the position information.

The object generation unit 37 is a unit for generating a predetermined object at a location corresponding to the surveyed location in the virtual space based on the coordinate information of the surveyed location acquired by the coordinate information acquisition unit 36. The connecting line generating means 38 is a means for generating a connecting line connecting one object and another object in the virtual space based on the user's U operation. The storage unit 39 is a unit for storing coordinate information acquired by the coordinate information acquisition unit 36 and connection line information regarding the connection line generated by the connection line generation unit 38.

6. Other Embodiments FIG. 5 is a front view of a surveying tool 20 in another embodiment. In the embodiment described above, the reflective member 12 is attached to the head-mounted display device 10 (FIG. 1), and based on the position information of the head-mounted display device 10 acquired using the total station T, , the position information of the surveying tool 20 was acquired. On the other hand, in another embodiment, a reflecting member 23 is attached to the surveying tool 20, as shown in FIG.

In another embodiment, the tool position acquisition means 34 uses the surveying tool 20 based on information obtained by an optical method using the reflective member 23 attached to the surveying tool 20 and the total station T (FIG. 1). Position information of the tool 20 can be acquired. Thereby, the position information of the surveying tool 20 can be acquired more directly, so that surveying accuracy can be improved.

In this case, it is preferable that the display device position acquisition means 33 acquire the position information of the head-mounted display device 10 based on information obtained by RTK positioning using GNSS signals. This is because in other embodiments, as shown in FIG. 13 may be mistakenly recognized as the reflective member 23 of the surveying tool 20. For other configurations, the same configuration as in the previously described embodiment can be adopted.
