Abstract

The invention provides a camera movement control method. Due to the fact that the maximum speed is set for camera movement, it is guaranteed that a camera can do uniform movement, and the accuracy of image acquisition is provided; in addition, a circulation path is formed by the first preset position, the second preset position, the third preset position and the fourth preset position, chip image acquisition can be achieved on a back-and-forth path of the camera movement, and the maximum efficiency is achieved. According to the camera movement control method, movement photographing of a chip can be completed in a 2*5 chip frame within 10 s, and the detection efficiency is four times higher than the manual detection efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical motion control, in particular to a camera motion control method. Background technique [0002] In the existing chip production process, the appearance of the chip is generally inspected manually to exclude defective products. However, this method is not efficient and highly dependent on people, requiring experienced people to operate. Therefore, those skilled in the art try to use image technology to detect the appearance of chips, but how to quickly obtain chip images to provide samples for image detection has become a difficult problem for those skilled in the art. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a camera motion control method for solving the problem of low efficiency in the prior art of using manual methods to detect the appearance of chips. [0004] In order to achieve the...
