其他摘要：Compared with the traditional automatic focusing method, the photoelectric automatic focusing technology has become the main research direction due to its advantages, such as high intelligence, speediness, accuracy and convenient control. In this paper, the principle photoelectric automatic focusing based on imaging processing is stated in detail, and two common automatic focusing methods are introduced in brief. Then, this automatic focusing scheme is designed and put forward. At last, the automatic focusing test is carried out, and its feasibility is verified.
