Angular accuracy computing and tracking accuracy assessing system and method

Abstract

The invention relates to the technical field of optoelectronic devices and discloses an angular accuracy computing and tracking accuracy assessing system and method. The system comprises a timing system unit, a data processing component, a rotating shaft system, a collimator component and an adjustable reflecting mirror. The collimator component and the adjustable reflecting mirror are arranged on a rotating arm of the rotating shaft system and are adjusted dynamically. The data processing component uses signals of the timing system unit for computing angular accuracy and accessing tracking accuracy according to motion data information of the rotating shaft system and target data information sent by an optoelectronic device to be detected. According to the system and method, testing covering most part of a view field can be completed only in an inner field, data analysis can be completed quickly, compared with an outer field fly-detecting testing mode, implementation cost is very low, implementation difficulty is small, and testing accuracy is high.

Description

technical field [0001] The invention relates to the technical field of photoelectric equipment, in particular to a system and method for calculating angle measurement accuracy and evaluating tracking accuracy. Background technique [0002] The angle measurement accuracy and tracking accuracy of optoelectronic equipment have always been one of the most widely demanded core technical indicators in the field of optoelectronic equipment. These indicators must be tested during the equipment development and commissioning stage, and regular tests are also required for calibration after long-term use in the field. Dynamic angle measurement accuracy refers to the difference between the real-time measurement of the target space pointing value and the true value of the photoelectric theodolite under the specified angular velocity and angular acceleration motion state. It is one of the most important technical indicators for measuring the photoelectric theodolite. [0003] At present, i...

Problems solved by technology

[0004] 1. Because the field test is limited by climate, cost, time, etc., the implementation of field inspection is costly and time-consuming, and it is difficult to cover the entire range of the field of view, and the post-event data analysis is cumbersome, which cannot meet the needs of rapid testing;

[0005] 2. The accuracy of the angle measurement accuracy test is not high, and it is difficult to meet the needs of the development and test of advanced optoelectronic equipment;

[0006] 3. It is difficult to create targets with high angular velocity and angular acceleration, and it is impossible to complete the tracking accuracy test and evaluation in real time

[0007] Therefore, how to solve the problem that the existing technology cannot satisfy the rapid test of angle measurement accuracy and tracking accuracy, the test accuracy is not high, and the tracking accuracy evaluation cannot be completed in real time has become a technical problem to be solved urgently.
