Problems solved by technology
However, for general image processing equipment from image acquisition, conversion to processing, the entire process of acquisition, conversion, and processing is not only the resolution of optical devices that affects the overall resolution of the system, but also the electronic circuits at the back end. Imaging systems have a greater impact. They have nonlinear time-varying characteristics, so that the resolution of actual equipment cannot only consider the impact of equipment optics, but should be considered from the entire photoelectric signal transmission channel to directly perform photoelectric image processing equipment. System Resolution Test
[0005] In view of the low degree of automation of the traditional optical device resolution test method, the test results are affected by certain human factors, and it is difficult to perform high-speed time resolution and equipment system resolution tests. An automatic test system for testing the spatial resolution of photoelectric image processing equipment

The invention discloses a spatial resolution test system for testing photoelectric image processing devices, which comprises a shell, a motion mechanism, a collimator A (1), a collimator B (2), an incident light angle regulation control circuit, an electric stop A (1a) and an electric stop B (2a) which are arranged in the shell. The invention utilizes two motors to control the indicant light angle between the two collimators, to make the distance between the light outlet of the collimators and an object of 3 to 10m and make the angle theta of the two parallel rays of 1 to 10 degrees. The spatial resolution test system can preset control parameters to automatically generate a multi-spectrum infinite optical test image light beam directly radiated to the screen of an object, and then the system collects the imaging result to be compared with an emission image source light beam to test the system level resolution of the equipment.
Description
technical field [0001] The invention relates to a device for testing spatial resolution, more particularly, an automatic spatial resolution testing system for testing photoelectric image processing equipment. Background technique [0002] Photoelectric image equipment is widely used. For example, image target recognition systems, autonomous robot systems, and visual measurement systems all rely on photoelectric image processing equipment. Therefore, the automatic detection technology of photoelectric image processing equipment performance has important practical value. The processing results of photoelectric image processing equipment are closely related to the image quality collected by the equipment, and the image quality depends to a large extent on the resolution of optical signals by the equipment. Therefore, the resolution is an important technical guarantee for the quality evaluation of image processing equipment. [0003] Usually, the resolution indicators of photoel...
