| Abstract: | A computer vision sensing system is introduced to detect the welding pools geometric parameters for pulse TIG welding. The arc light disturbance is reduced by cooperating the special sampling sequence with the narrow band composed filter scene. Based on the analysis of the image features,a image processing algorithm is developed. By the system and algorithm,several important welding pools parameters can be detected such as the welding pools maximum width,half length,rear area and rear angle. This work lays solid basis for further real time control of the welding process. |
