Image Processing Method to Detect Seam Track of Thin Sheets
-
摘要: 针对航空发动机关键部件的薄板对接、搭接焊缝的自动焊接问题,以CCD(Charge coupled device)摄像机直接拍摄为手段提取焊缝轨迹,提出了一种比较通用的算法和思路,包括边缘点的检测和边缘线的提取,并在几个关键环节对其进一步改进.实验表明,此算法具有较强的适应性,也为解决焊缝轨迹提取这一焊接自动化和弧焊机器人的智能化领域的关键技术提供一定的技术参考.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.
