英文摘要	The invention relates to a laser tailored welding curved surface abutted seam measuring method and a realization device thereof. The method comprises the following steps: generating circular structured light by utilizing a circular laser, and generating horizontal-I linear structured light by utilizing a horizontal-I linear laser, wherein the circular structured light and the horizontal-I linear structured light are projected to the surface of a curved surface abutted seam and intersected; collecting and obtaining an abutted seam surface gray level image comprising the horizontal-I linear structured light and the circular structured light through a sensing unit, and transmitting the collected image to an image processing unit; and carrying out processing by the image processing unit on the collected image to obtain three-dimensional position and normal vector of the curved surface abutted seam center and abutted seam width and mismatching values. The device comprises the sensing unit for collecting the laser tailored welding curved surface abutted seam image and transmitting the image to the processing unit; the image processing unit for carrying out processing on the collected abutted seam image; and a parameter setting and control unit for setting parameters and in communication connection with the sensing unit, the image processing unit and an upper computer. The laser tailored welding curved surface abutted seam measurement precision is improved, online tracking adjustment of the pose of a welding torch for curved surface laser tailored welding is realized favorably, welding quality is ensured.
