Image Processing Method to Detect Seam Track of Thin Sheets

Abstract

Aiming at automatic welding of butt and lap joints of the seam track of the key components of aviation engine by means of CCD camera direct shooting to obtain seam track, a relatively universal algorithm and thought was put forward including detecting edge points and obtaining edge line. Several key steps were improved. The experiments shows that the algorithm and thought possesses have better adaptability and can give some technical reference to solve the key technique of obtaining seam track in the field of welding automation and intelligence of welding robot.
