[0002] The photoelectric tracking platform mainly realizes the tracking and measurement of the target, and is generally equipped with detection cameras of various bands. The quality of its imaging is directly related to the success or failure of the task, so it is very important to design a good automatic focusing control system; in the past, the photoelectric tracking platform Most of the controllers of the automatic focusing system use a single-chip microcomputer as a processor, but the single-chip microcomputer has low reliability, complex interface, inconvenient operation and low integration. These shortcomings have brought difficulties to the automatic focusing control of the photoelectric tracking platform.
