Research on Connecting Plate Outline Measurement System Based on Image Processing

This paper aims to accurately obtain connecting plate outline. First, a camera captured a connecting plate image, then transmitted it to a computer, next converted it to a gray image, after that used Canny operator to extracted its edge information, and converted the pixel points of the gray image to rectangular coordinate values, at last found out all of the vertices of the connecting plate. Research result shows that the system is simple, its accuracy is less than 0.3%, and the data processing is convenience.
