The wide-angle CCD imaging system (1) comprises a wide-angle CCD optical system (3), a CCD photosensitive array (4) and an inclination angle sensor (5). The CCD photosensitive array (4) is arranged at a position below and perpendicular to the wide-angle CCD optical system (3). The CCD photosensitive array (4) is perpendicular to a central optical axis of the wide-angle CCD optical system (3). The inclination angle sensor (5) is arranged in parallel with the CCD photosensitive array (4). The apparatus is advantaged in that: with the inclination angle sensor (5), an angle of the CCD photosensitive array (4) relative to the earth ground horizontal plane can be measured in real time, such that the apparatus is not restricted by geographic environments, and errors caused by a position-regulated angle measuring apparatus can be avoided. The imaging of the apparatus is precisely oriented. Measured information is collected and processed by using the portable computer (2), such that measuring results are obtained. The angle measuring speed is high, and the angle measuring precision is high.
Description
Technical field
The present invention relates to the earth angle measuring instrument technical field, particularly a kind of CCD angle-measuring equipment.
Background technology
The device that is used at present angle measurement mostly is mechanical type angle-measuring equipment and absolute encoder formula angle-measuring equipment, how effectively to shorten the angle measurement time in the earth mapping, the error that effective elimination mechanical drive is brought, the Resolution Error of absolute value encoder itself, improving angle measurement accuracy, is the important topic that Surveying and Mapping Industry is concerned about and is made great efforts to implement.
The error that existing machinery formula angle-measuring equipment brings owing to mechanical drive, the operator needs according to same direction casing pressure target when the operation angle-measuring equipment.In the casing pressure process, if there is having above phenomenon, need to rotate again again casing pressure target; Owing to also having the impact of the error of division etc. in the mechanical drive, cause angle measurement accuracy not high, obtain higher measuring accuracy such as need, precision is debug in the processing that needs to improve part.Absolute encoder formula angle-measuring equipment is because the restriction in space, and the figure place of individual pen absolute encoder is less, and precision is lower, adopts mechanical drive to add array mode with the multi-turn absolute encoder more.But mechanically operated error will be brought in the angle measurement accuracy again, affect angle measurement accuracy.
At present, the develop rapidly of CCD imaging technique is for the CCD angle measurement provides powerful technical support.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the CCD that a kind of measuring accuracy is high, speed is fast, simple to operation angle-measuring equipment is provided.
Purpose of the present invention is achieved through the following technical solutions:
The CCD angle-measuring equipment, it comprises wide-angle CCD imaging system and a portable computer, wide-angle CCD imaging system links to each other with portable computer by circuit; Described wide-angle CCD imaging system comprises wide-angle CCD optical system and CCD photosensitive array, and the CCD photosensitive array is arranged under wide-angle CCD optical system vertical, and the CCD photosensitive array is perpendicular to the central optical axis of wide-angle CCD optical system; Described wide-angle CCD imaging system also comprises an obliquity sensor, and obliquity sensor parallels with the CCD photosensitive array.
Described wide-angle CCD imaging system also comprises a shell, and wide-angle CCD optical system, CCD photosensitive array and obliquity sensor all are fixed in the shell.
Described portable computer has a screen signal receiving module and a screen signal processing module.
The present invention has the following advantages:
The present invention is provided with wide-angle CCD imaging system, so that device need not the target that any rotation can collect-10 °～90 ° of height, 360 ° in orientation, and wide-angle CCD imaging system is provided with an obliquity sensor, can go out the CCD induction arrays with respect to the angle of the earth surface level by real-time testing, so that device is not subjected to whether to install the restriction of level, can not produce error because of the inclination of device, measurement result is accurate.
The present invention adopts the imaging of CCD induction arrays, and accurately directed, speed is fast, and collects, processes metrical information by portable computer, draws measurement result, so that device angle measurement speed is fast, precision is high.

Wide-angle CCD optical system 3 can collect the target in-10 °～90 ° of height, 360 ° in orientation.
The course of work of the present invention is as follows: just-10 °～and target in 90 °, the 360 ° of scopes in orientation is imaged on the CCD photosensitive array 4 by wide-angle CCD optical system 3; Simultaneously, obliquity sensor 5 is measured the relative to the earth angle of surface level of CCD photosensitive array 4.
As shown in Figure 3, then high and low angle zero-bit 7 is set, the fixed position is set to orientation angles zero-bit 8 arbitrarily simultaneously.
Corresponding unique height, the orientation angles value of pixel of the screen signal that portable computer 2 gathers.The signal projection that CCD photosensitive array 4 is gathered can obtain measured target with respect to the high and low angle value of the earth surface level with respect to the angle value of demarcating the orientation zero-bit to the earth surface level.
