Description

Dynamic stereoscopic vision detection device and method

Technical Field

The invention relates to the technical field of medical equipment, in particular to a dynamic stereoscopic vision detection device and a method.

Background

Stereoscopic vision is an advanced visual function of human binocular vision. The human body judges the distance between the object and the concave-convex shape of the object through stereoscopic vision. In life, 3D movies and virtual reality technologies all require users to have good stereoscopic vision. Stereovision is also a prerequisite for practitioners engaged in fine manipulation related professions, such as astronauts, pilots, microsurgical procedures. Disorders such as strabismus are often associated with stereovision abnormalities, which have been shown to occur in about 5% of the population. Since there is a distance of about 60-65mm between the eyes, the eyes view the same visual scene from different positions, respectively, and points at different distances from the observer generate images at different distances from the fovea of the eyes, thereby generating binocular parallax. When binocular parallax is within a certain range, a single image with depth, i.e., stereoscopic vision, can be formed through the visual cortex. The stereoscopic vision can accurately perform foreign object positioning and self positioning in the external environment. At present, slightly different images are usually displayed to eyes through different technologies such as polarization imaging, random dot patterns and the like, so that stereoscopic vision is formed in the brain. The currently common stereo vision detection methods in clinic comprise the modes of a Fribsy test, a Titmus test, a random point stereogram, a synoptic camera and the like. These examination methods are widely used in clinic due to their convenience. But still has the problems of monocular clues, fixed patterns, only qualitative screening of stereoscopic blindness, low repeatability and the like.

Studies have shown that patients who appear to be stereoblind in static stereo sharpness examinations can still recognize changes in target depth. At present, the clinical stereoscopic vision detection mode is limited to static stereoscopic vision sharpness detection, and a convenient dynamic stereoscopic vision sharpness detection tool is not available. But depth information of both eyes usually appears in dynamic form, both in real life and in 3D entertainment.

During the visual signal transduction process, signals are recognized by the retina and then transmitted to the brain to form an image. Retinal ganglion cells include M and P ganglion cells, wherein high-temporal frequency, low-spatial frequency signals are conducted primarily into the brain via M cell-related dorsal pathways that primarily process "where" information, including depth, motion, and location information. The damage to the passageway is associated with a reduced depth and motor vision recognition. Studies have shown that glaucoma patients may develop post-retinal intracranial neuropathy, particularly M cells in the lateral knee, due to the occurrence of cross-synaptic degeneration, with a greater susceptibility to damage in glaucoma. Therefore, detection of abnormalities in depth and motion signals related to the pathway is of great importance to screening and follow-up of glaucoma patients. The dynamic stereo vision detection contains depth and motion information, and the detection method may have important significance for screening and diagnosis of glaucoma patients.

The currently few available dynamic stereoscopic vision detection methods are only used for scientific research, cannot be applied to clinical patient assessment, lack of standard and convenient detection schemes at present, and have the problems of low repeatability, low sensitivity and specificity to target diseases and the like. Therefore, it is very necessary to design a detection means for dynamic stereoscopic vision, and provide a standard and repeatable high dynamic stereoscopic vision detection means for clinical application.

The current methods clinically applied to testing stereoscopic vision such as Titmus have monocular clues and have low repeatability. Different detection methods are often needed for short-distance and long-distance stereoscopic vision, different evaluation modes are needed between the two methods, and the comparability is poor.

In addition, the current dynamic stereoscopic vision detection mode is still in a scientific research stage, the movement mode of the sighting target is limited, and the sighting target is lack of more standard parameter settings, such as random point size, sighting target size and the like, so that the clinical application of the sighting target is limited.

Detailed Description

The present invention is described in more detail below to facilitate an understanding of the present invention.

Dynamic vision refers to the ability of an observer to discern details of a visual target in the presence of relative motion between the subject and the visual target. Currently, the clinical detection of visual functions (such as eyesight, stereoscopic vision and the like) mainly comprises the evaluation of static visual functions of a subject, and the evaluation of dynamic vision is relatively less. However, since visual targets in daily life are mainly sports, and with the increasing medical level, people are increasingly focusing on visual quality in real life. The current common visual function examination can not fully understand the actual visual state of a patient in daily life, the clinical needs can not be met far by the evaluation of simple static vision, and the influence of the visual function of a subject on the life ability can be understood by assisting with dynamic vision detection.

Furthermore, different types of neural cells in the visual pathway have a propensity to transmit different types of visual signals: the M channel is mainly used for conducting visual signals with low spatial frequency, low contrast and high time frequency, and the percentage of the transmitted signals of the M channel is gradually increased along with the increase of the time frequency of the visual signals, so that the M channel is mainly used for conducting motion visual information; in contrast, P-paths primarily conduct visual signals of high spatial frequency and low temporal frequency, primarily responsible for the identification of morphological details of the object. Studies have shown that the M-pathway of patients with early glaucoma is selectively impaired, so that abnormalities in dynamic vision may occur earlier than other abnormalities, and that assessing dynamic vision may be of early diagnostic value.

The evaluation means of dynamic vision are mainly divided into: dynamic vision testing of optotype rest and optotype movement.

(1) Dynamic vision testing with stationary optotype: the method is mainly used for assessing the vestibular function, has relatively few application in clinical ophthalmology, and is only limited to be used for primarily identifying the asthenopia and dizziness caused by the vestibular function damage.

(2) The dynamic visual acuity test of the movement of the optotype is mainly used for evaluating the tested dynamic visual acuity of clinical ophthalmology, and a plurality of test systems of the type are developed at present and can be mainly divided into a mechanical optotype display method and a computer optotype display method.

(1) Mechanically displaying the optotype: the method has the advantages that the method is closer to reality and is not influenced by the refresh frequency and the corresponding speed in the computer display; but has the disadvantage of requiring specific equipment.

The driving device and the sighting target integrally move: according to the self-made optotype of the LogMAR visual acuity chart, a power model vehicle is used as a driving device, a plurality of optotypes which are different in size and are gradually arranged in a shrinking mode from left to right are carried on the loading vehicle each time, the loading vehicle moves from left to right in front of a tested person at a certain speed, and a subject is ordered to recognize the optotype moving on the loading vehicle from left to right under the condition that the head is kept still.

The driving device not only moves the sighting target: such as the KOWA HI-10 (Kowa company, ltd., japan) system. The system includes a mirror vertically fixed to a turntable, the rotational speed of which is controlled by a variable speed motor, and a projector which projects a Landolt-C optotype onto the mirror and which specularly reflects the optotype onto the screen. The mirror rotates at different speeds to realize horizontal movement of the optotype from left to right at different speeds, and the movement speed of the optotype is set to be gradually slowed down. The subject is instructed to recognize the optotype.

(2) The computer displays the optotype: the method comprises the steps of generating a dynamic visual target with adjustable size, movement speed and movement mode through computer software, directly displaying the visual target on a screen or utilizing a projector to show the visual target on a curtain, ordering a subject to distinguish the opening direction of the visual target, and recording a test result of the minimum visual target which can be distinguished at a certain speed. The method does not need specific examination equipment, and is convenient for wide clinical popularization. But has the disadvantage of being limited by the screen refresh frequency and response time.

Stereoscopic vision is the visual perception function of positioning a target object in a space depth coordinate by two eyes, and is also called depth vision, which is the highest form of binocular vision. Depth perception due to a small level difference on the retinal images of both eyes is the basis for the formation of stereoscopic vision. The stereoscopic information processing involves a plurality of central vision processing sites. Clinical stereoscopic detection includes near-distance stereoscopic vision and far-distance stereoscopic vision.

Common methods for short-range stereoscopic inspection include a Titmus inspection chart, a Frisby inspection chart, a random point inspection chart.

The Titmus inspection chart is formed by separating binocular images by applying a polarized light principle, and consists of a fly screening qualitative chart, an animal quantitative chart and a ring quantitative chart, wherein the parallax is divided into 9 stages from 800 to 40 and is used for detecting rough local stereoscopic vision. The three-dimensional vision detection device has the advantages of convenience in operation, easiness in understanding of a subject, and capability of being used for three-dimensional vision detection of low-age children. However, the Titmus examination chart has the artificial factors of monocular clues, implication signals and the like, is easy to memorize, and can be guessed, so that the false negative rate is higher, and the repeatability is poor.

The Frisby stereo test chart is the stereo test card with highest precision at present, does not need to wear red and green eyes or polarized light eyes, and is suitable for special patients such as low-age children, language disorder, intellectual disorder and the like. The Frisby stereo test chart consists of three stereo test plates with different thicknesses. Each three-dimensional detection plate is printed with four patterns, one of the patterns is a three-dimensional image, and a background image and a foreground image of the three-dimensional image are respectively printed on two sides of the detection plate, so that physical depth difference exists between the two patterns. By changing the thickness of the inspection board and adjusting the distance between the inspected person and the inspection board, the parallax of 20-600' can be detected.

The random point stereogram is composed of random points for detecting fine and advanced overall stereoscopic vision functions. A clinically common application is a red-green random dot stereogram, where a patient wears red-green glasses for separating binocular images. The random point stereogram is composed of points which are distributed randomly, binocular parallax is single, monocular clues are not generated, and the accuracy and the repeatability are high. In addition, the third generation of the pigment random point stereogram adopts an electronic grating carrier technology, stereoscopic vision detection can be carried out without wearing 3D carrier glasses, the method is high in repeatability, convenient to clinically apply without wearing glasses, and only short-distance stereoscopic vision detection can be carried out.

Remote stereoscopic vision detection is commonly used with a common-view machine drawing and a remote random point perspective view. When the stereoscopic vision is detected by the same-vision machine picture, the parallel light is emitted into the eye to be detected by the light source, and two pictures with micro displacement on the focal plane of the ocular lens are observed by two eyes to form micro horizontal parallax on retina, and the size of the horizontal displacement of the pictures is adjusted to detect the stereoscopic vision. The common vision machine is a multifunctional comprehensive diagnosis and treatment instrument which is not a special instrument for stereoscopic vision inspection, so the common vision machine has the problems of difficult carrying and high price. In addition, the stereoscopic vision detection process of the co-vision machine picture is complicated, needs understanding and cooperation of a patient, and has great limitation in application in low-age children. The remote random point stereogram is also composed of random points, no monocular clues exist, and clinical researches show that the remote random point stereogram has no obvious difference from the inspection result of the same-vision machine drawing. Due to the convenience of the use, the method has important significance in rapidly screening the stereoscopic blindness and monitoring the stereoscopic vision change in clinical work, and is particularly suitable for detecting the stereoscopic vision of low-age children.

Dynamic stereoscopic vision detection principle:

dynamic stereo vision includes both motion and stereo vision information. The detection process involves a visual target generation mode, a visual target display mode, a binocular parallax formation mode, a task of a tested person and the like.

1) Optotype generation mode: optotypes are typically composed of random points or generated by virtual reality techniques.

2) Visual target display mode: including two modes of displaying recorded video and computer generation. The recorded video generates a video containing dynamic stereoscopic vision through computer software, and a plurality of videos are manufactured according to different parallaxes, and the method has the defects that the variation of the sighting marks is constant, the method cannot be adjusted in the detection process, and the video can be only used under fixed detection conditions after the video is manufactured. The computer generation is to generate random point images by using computer software, and has the advantage that an inspector can adjust inspection parameters according to different testing conditions, so that the method is suitable for various detection conditions.

3) Binocular parallax formation mode: (1) generating random points through a computer to respectively form two images with micro parallax, wherein the two images can be positioned in the same image, a subject wears red-green glasses or polarized glasses, and a graph with horizontal parallax is formed on retina through binocular observation; (2) and generating a stereoscopic image through a virtual reality technology, and enabling a subject to wear polarized glasses to form binocular vision.

4) Subject task: in one task, the graphics on the screen may be presented as single or multiple optotypes. When a single optotype is displayed, the subject is required to recognize the characteristics of the optotype, such as the shape of the optotype, the direction of the E-optotype, the direction of the missing portion of the circle, whether the pattern is prominent or depressed. When a plurality of targets are displayed, the subject is required to recognize targets different from other targets, such as targets with different directions of protrusions, different shapes and different parallaxes.

At present, dynamic stereoscopic vision detection modes are divided into two types: dynamic stereoscopic detection with constant parallax and dynamic stereoscopic detection with variable parallax.

1) Parallax-constant dynamic stereoscopic detection: the method uses computer software to generate a red-green random point stereogram with adjustable image size, parallax and movement speed, and generates regular figures of circles, squares and triangles on a screen. When in detection, a tested person wears red-green glasses, the shape of a sighting target on a screen is distinguished, and the minimum parallax which can be distinguished at a certain speed is recorded as a test result. The method generates the graph by utilizing the random point stereogram, has no monocular clues, does not need specific examination equipment, and is convenient for clinical popularization. The method has the defects that the method is limited by the screen refresh rate and the response time, the movement direction of the optotype is limited in the existing designs, and the random point parameters and the optotype size are not standard. The parallax changes are mostly of fixed parallax size, the span is larger, and the detection precision is lower.

2) Dynamic stereoscopic detection of parallax changes: the random point stereogram is generated by computer software or the image is generated by virtual reality technology, the sizes and the shapes of the targets are the same, the parallax of each target is increased from an initial state along with time, and the parallax is reduced at a constant speed after the parallax is increased to a maximum value. One of the optotypes has a disparity magnitude difference from the other optotypes. The detection result is the difference of parallax of the two types of optotypes.

In view of the problems existing in the prior art, the invention provides a detection system capable of conveniently testing dynamic stereoscopic vision in the ophthalmic clinical diagnosis and treatment process. The system comprises two test modes of a dynamic stereoscopic vision detection system with constant parallax and variable parallax.

Dynamic random point stereogram test equipment and test environment:

the test equipment comprises a test computer, a screen, a judging device, a control panel and red-green glasses. The screen is connected with the computer and used for displaying the dynamic random point stereogram. The judging device is connected with the computer and the screen, the information of the key to be pressed is transmitted to the computer, and the program can automatically judge whether the key is correct or incorrect. The control panel is connected with the computer and used for adjusting the parallax size of the sighting target or the testing parameters such as the parallax size, the movement speed or the parallax changing speed and the like. The computer is connected with other components and used for running the detection program to display a dynamic random point stereogram, judging whether the direction pressed by the judging device or the optotype selection is correct or incorrect, and receiving the control information of the control panel. The red-green glasses are also called red-green filters, the color of the red-green glasses is consistent with the red-green random points displayed on a screen, one eye is a red lens, the other eye is a green lens, and the same-color patterns cannot be observed through the lenses. As the screen is viewed through the red lens, the red random dots coincide with the lens colors, only the green random dots can be observed, and the other eye wearing the green lens can only observe the red random dots. The same figure with a certain parallax is observed by both eyes, thereby forming stereoscopic vision.

The requirement of the test screen is selected according to the movement speed or parallax change speed of the optotype: if the movement speed or parallax change speed of the optotype is smaller than 50 degrees/second (low-speed test), a screen with refresh frequency of 60Hz can be selected, and most of screens on the market can meet the test requirement; if higher speed testing is required, a higher refresh rate screen support, such as 144Hz or 200Hz, is required. The response time of the test screen should be less than 4ms, and for a optotype that is tested for high speed movement, it is recommended that the test screen response time be less than 1ms.

Four keys are respectively drawn on the determiner (see figure 1), and the arrows of up, down, left and right are respectively corresponding to the opening directions of four E optotypes of vertical upward, vertical downward, horizontal leftward and horizontal rightward, the directions of four circular notches of vertical upward, vertical downward, horizontal leftward and horizontal rightward, or the graph corresponding to the circle, the square and the triangle (the right arrow is not used), the judging device is held in the hand by a tested person, after the optotype displayed on the screen is observed by the tested person, the corresponding key is pressed down, and then the error of the tested person is judged automatically by the computer program.

In the parameter setting interface shown in fig. 2, a random dot size, density, optotype size, background map parallax, inspection distance may be set.

In the parallax constant test mode parameter setting interface shown in fig. 3, a parallax size, a movement speed, a movement direction, a pattern (E/circle), a pattern direction (optotype direction) may be set.

The size adjustment in the parameter setting interface requires manual input.

In the parallax constant test mode, after the upper and lower keys in the parallax setting module are clicked, corresponding parallaxes are respectively increased/decreased according to preset parameters. After the upper button and the lower button in the speed setting module are clicked, the corresponding cursor moving speed is respectively increased/decreased according to preset parameters. After clicking on the horizontal (left/right), vertical (up/down), left (up/down) and right (up/down) directions in the movement direction setting module, the horizontal movement, the vertical movement and the diagonal movement of the optotype are respectively set, and the contents in brackets are starting points of the movement of the optotype, such as the left (up) directions, and the optotype moves along the diagonal from the left up to the right down directions. Clicking the graphic type button switches the optotype to an "E" optotype, a circle lacking 60 deg. or a regular graphic. After the up, down, left and right keys in the sighting target direction are clicked, four E sighting target opening directions of vertical upward, vertical downward, horizontal leftward and horizontal rightward are respectively arranged, and four circular notch directions of vertical upward, vertical downward, horizontal leftward and horizontal rightward are respectively arranged, or the figures corresponding to the circular, square and triangle are respectively arranged (right arrow is not used).

In the parallax change test mode, after the upper and lower keys in the parallax setting module are clicked, corresponding parallaxes are respectively increased/decreased according to preset parameters. After the upper key and the lower key in the parallax setting module are clicked, the corresponding parallax is increased/decreased according to preset parameters. After clicking the up and down keys in the parallax changing speed setting module, the corresponding parallax changing speed is respectively increased/decreased according to preset parameters. Clicking the graphic type button switches the optotype to an "E" optotype, a circle lacking 60 deg. or a regular graphic. After the up, down, left and right keys in the sighting target direction are clicked, four E sighting target opening directions of vertical upward, vertical downward, horizontal leftward and horizontal rightward are respectively arranged, and four circular notch directions of vertical upward, vertical downward, horizontal leftward and horizontal rightward are respectively arranged, or the figures corresponding to the circular, square and triangle are respectively arranged (right arrow is not used).

The illuminance of the test environment is controlled between 170 and 180lux, strong light is prevented from being directly irradiated on the screen, and the ambient temperature is suitable for the comfort of patients.

The shape of the visual target E shown is drawn according to the international standard visual chart, i.e. each stroke of the visual target and the interval between each stroke have the same thickness.

The circles containing the up, down, left and right direction information are shown as a circle lacking 60 °, and the lacking portions thereof are centered at 0 °, 90 °, 180 ° and 270 °, and lack 30 ° up and down, respectively.

The size of the optotype is determined by the set viewing angle and the test distance. The circular diameter is equal to the square side length and the triangular side length. Circle diameter = 2 x inspection distance arctan (view angle/2/60), inspection distance in mm and view angle in arcinute.

Parallax-constant dynamic random point stereogram detection:

the parallax constant dynamic stereoscopic vision detection system has a dynamic random point stereoscopic image display function, a parallax rapid switching function, a movement speed rapid switching function, a movement direction rapid switching function, an automatic test function, a test data automatic storage function and a test result automatic output function. Correspondingly, the parallax-constant dynamic stereoscopic vision detection system comprises a random point stereoscopic image display unit, a random point stereoscopic image control unit, a data processing unit, a data storage unit and a data output unit, wherein the connection mode of different unit modules is shown in fig. 3.

Dynamic random point stereogram display function:

the random point stereogram display unit can display random point stereograms with different parallax sizes, different movement speeds, different graphic shapes and different movement directions on a screen, and fig. 6 is a static schematic diagram with four different directions, and arrows represent the movement directions of optotype. The optotype is in the shape of an E in different directions, lacking a 60-degree circle or regular pattern (circular, square, triangle). The optotype size is set according to different test distances and visual angle sizes. The system can automatically and randomly display, and can manually control and display four different opening directions or pattern shapes by clicking a key in pattern switching (sighting target direction) control on a control panel. The up, down, left and right directions of the sighting target respectively correspond to the E sighting target in the directions of four openings of vertical upward, vertical downward, horizontal leftward and horizontal rightward, and the directions of four circular notches of vertical upward, vertical downward, horizontal leftward and horizontal rightward, or correspond to the figures of circles, squares and triangles (right arrow is not used). And the movement direction of the switching sighting target can be controlled by the direction on the control panel. The parallax varies in magnitude between 10-1500'. The speed of movement varies between 10 and 100 dps.

Parallax fast switching function:

the parallax quick switching function can quickly switch the parallax of the visual target, and the switching strategy is to quickly switch between adjacent parallaxes, and the implementation mode is realized by clicking an up button and a down button in a parallax control module on the control panel. The system sets a series of parallaxes in the program in advance, and the range is 10-1500'. Before the test starts, setting the parallax value of each key increase and decrease in the setting interface in advance, for example, setting the parallax of each key increase and decrease to be 30 ", setting the switching interval to be 30", pressing the up direction key can increase 30 ", and pressing the direction key can decrease 30", so as to realize rapid switching between adjacent parallaxes.
