Point cloud meshing method, apparatus, device and computer storage media

An apparatus comprising:

• one or more processors;
• memory;
• a reconstruction module stored in the memory and executable by the one or more processors to perform a mesh reconstruction on point cloud data corresponding to a target object to obtain a reconstruction model for characterizing a surface contour of the target object;
• a registration module in the memory and executable by the one or more processors to:
• determine a type of the target object,
• determine a standard model of the target object based on the type of the target object,
• perform image registration between the reconstruction model and the standard model;
• a determination module in the memory and executable by the one or more processors to determine a mesh portion in the registered reconstruction model that does not overlap with the standard model, the determination module used for setting a difference operation result that is obtained by performing a three-dimensional graphic Boolean operation on the registered reconstruction model and the standard model as the mesh portion of the registered reconstruction model that does not overlap with the standard model;
• and
• a removal module in the memory and executable by the one or more processors to remove the determined mesh portion from the registered reconstruction model to obtain a resulting reconstruction model of the target object.

One or more computer readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• performing a mesh reconstruction on point cloud data corresponding to a target object to obtain a reconstruction model for characterizing a surface contour of the target object;
• determining a type of the target object;
• determining a standard model of the target object based on the type of the target object;
• performing image registration between the reconstruction model and the standard model;
• determining a mesh portion in the registered reconstruction model that does not overlap with the standard model by setting a difference operation result that is obtained by performing a three-dimensional graphic Boolean operation on the registered reconstruction model and the standard model as the mesh portion of the registered reconstruction model that does not overlap with the standard model;
• and
• removing the determined mesh portion from the registered reconstruction model to obtain a resulting reconstruction model of the target object.
