The electronic control box can control the two-dimensional turntable to rotate in two dimensions according to a certain working mode and drive the camera mounted on it to accurately track and image the moving target in space. In order to detect the dynamic tracking accuracy of the space high-resolution optoelectronic tracking and aiming system and the imaging quality of the camera, it is necessary to establish an indoor dynamic imaging test device to test the various performances of the space high-resolution optoelectronic tracking and aiming system.
[0003] With the development of large-aperture, long-focal-length, spatially high-resolution optoelectronic tracking and aiming systems, their weight and volume have increased significantly, and their accuracy and other performance indicators have also been greatly improved. This requires the corresponding indoor dynamic imaging test equipment to be larger in size and scale, more comprehensive in functions, more flexible and accurate in testing methods, and have higher testing accuracy.
[0004] However, the existing indoor dynamic imaging test equipment has a small span (less than 4 meters) and low accuracy (less than 15 seconds), which cannot meet the requirements of large space and high accuracy for the spatial high-resolution optoelectronic tracking and aiming system with large aperture and long focal length, nor can it track and perform performance tests on the spatial high-resolution optoelectronic tracking and aiming system within the full motion range; in addition, the existing indoor dynamic imaging test equipment can only provide an autocollimator for infinitely far spatial moving targets with single-axis rotation (i.e., only the azimuth part or only the pitch part) to test the capture and tracking performance of the spatial high-resolution optoelectronic tracking and aiming system, and the movement speed and acceleration of the device cannot meet the requirements of fast startup and fast movement.
