Abstract:
     The invention relates to a sealing radioactive source leakage detecting technique, especially providing a visual servo system of sealing radioactive source leakage automatic testing platform, and relative method, wherein said system comprises: a computer (2), a camera (3), an executer (4), an executer controller and special altitude estimate visual algorism. And the method comprises: S1, converting colorful image into gray image or collecting gray image; S2, using Canny edge algorism to process the gray image to obtain edge image; S3, using edge fine technique to fine the edge into single pixel connecting edge with eight nearby regions; S4, removing noise; S5, building the model of upper surface geometric character of radioactive source work piece; S6, building the homography matrix between image plane and upper surface of work piece; S7, transmitting the calculated result to the mechanical arm controller.
