Surface deformation defect generation method and device and storage medium

The invention relates to the technical field of data generation, in particular to a surface deformation defect generation method and device and a storage medium. The surface deformation defect generation method comprises the following steps: calculating a support plane for an input three-dimensional point cloud data set and carrying out dimensionality reduction to obtain an original depth map data set; extracting the original depth map data set to obtain a defect morphological feature set; performing random transformation on the defect morphological feature set, and fusing the defect morphological feature set with a normal depth map data set to obtain a generated depth map data set; an existing small sample learning and data generation method is difficult to meet actual production requirements and cannot solve the problem of data shortage, and the surface deformation type defect generation method is designed, so that a large amount of data which has authenticity, diversity and reliability and contains surface
