Design Of Automatic Focusing System For Reversing Camera

In today’s society, autofocus technology has become the core content of digital imaging system, it can effectively enhance competitiveness of our country’s digital imaging products.The purpose of this paper is to use autofocus technology makes the focal plane of lens and CCD plane, the camera in a specific focal length into clear.Traditional way for manual focus focus, although the resolution of the human eye is higherm,but the overall working efficiency is low, especially in the condition of not intermittent work precision will decline.According to the requirements of practical engineering,this system was designed by the use of the principle of digital image processing,it can realize the camera for newly produced reverse the whole process of automatic focus and locked,in improving the production efficiency at the same time makes the focusing accuracy greatly ascend, saves the cost of production.
