【Abstract】 To resolve the task of information extracting of image property in arc welding robot visual servo, this paper designed a serial of digital image process algorithms with certain robustness according for the property of work environments. Applying the presented algorithms, the information of markers in natural background is obtained accurately, and as the basis of following work. In the paper, we use oriented spot automatic threshold choice and connected area segmentation algorithms, and experiment results illustrated the chosen algorithms were suitable to our special environments and were satisfied.更多还原
