Paper Abstract
A machine vision system is used to extract the laser spot area and the position of the spot center on the workpiece. Its overall structure consists of lathe, camera, PC and laser. It has the advantages of simple structure, high integration and flexible system design. Firstly, the area of the spot illuminated to the workpiece is obtained, and the power density and the temperature of the spot center are deduced. The position of the spot center on the workpiece is obtained to facilitate the adjustment of the laser irradiation position. In order to detect the light spot on the surface of a cylindrical workpiece, the pin-hole imaging model and the cylindrical surface expansion algorithm are used to expand and fit the surface part of the light spot on the surface of a cylindrical workpiece, and the Hough transform is used to locate its exact position.
