To solve the problems existing in the traditional automatic planning algorithm of surfacing repair path, an automatic planning algorithm of surfacing repair path based on 3D vision technology is proposed. Firstly, the one-way planning distance is calculated, the pixel value containing weld in the target image is set to 0 based on 3D vision technology, the threshold value of weld is calculated, the surfacing repair path planning target is constructed, and the planning nodes are set. The, calculate the displacement value of the component that needs welding deformation, and get the automatic planning result of surfacing repair path. The experimental results show that the target location result obtained by the proposed algorithm is more accurate, and the characteristics of the weld test sample image can be accurately planned. The average root mean square error after the supplement is smaller, which is 0.1 cm, indicating that the proposed method can effectively improve the path planning effect.
