Research on online measurement method of fuse parts diameter based on laser projection method

In order to effectively shorten the time for online measurement of the diameter of fuzed parts by laser projection method, this paper designs a simple and effective diameter solving method - analytical approximation triangle method, and simulates the influence of parameters such as the position of the laser source and the position of the measurement center on the measurement results of the diameter of a certain fuzed part in the measurement process. The simulation results show that when the analytical approximate triangle method is used to solve the diameter of a fuse component measured online by laser projection, the distance between the laser source and the measured component should be increased appropriately, and the distance between the CCD panel and the measured component should be reduced.
