Problems solved by technology
[0002] At present, the data stitching methods for white light 3D scanning mainly include marker point stitching, texture stitching, and point cloud feature stitching. The wrong place is not easy to splice. Texture splicing is only suitable for scanning objects with or without texture features on the surface of the object. Marker splicing is only suitable for marking points on the surface of the object.
Each of the above three methods is individually applicable to different scenarios. However, in the prior art, only one of the splicing methods can be selected for scanning according to the current scene requirements. Once the splicing fails, other splicing methods cannot be used to make up for it. resulting in a higher splicing error rate
[0003] Aiming at the problem of low robustness and error-prone data stitching in 3D scanning technology in related technologies, no effective solution has been proposed yet

The invention relates to a three-dimensional scanning splicing method and device, an electronic device and computer equipment, and the method comprises the steps: obtaining to-be-spliced point cloud data, recognizing mark point features, texture features and point cloud features carried in the point cloud data, and splicing the point cloud data according to the mark point features when the recognized mark point features meet a preset condition; and when the mark point features fail to be spliced, selecting other splicing features to splice the point cloud data, selecting a corresponding splicing mode to splice the point cloud data according to the order of the robustness of the splicing modes. When one mode fails to splice, the other splicing modes can be used for making up, so that in the three-dimensional scanning process, the robustness of splicing the point cloud data is improved.
