Abstract

The invention relates to a three-dimensional grid reconstruction method and device, an electronic device and a storage medium, and the three-dimensional grid reconstruction method comprises the steps: obtaining the position information of a voxel corresponding to updated point cloud data of a to-be-reconstructed object, determining a patch set of the voxel corresponding to the updated point cloud data according to the position information, determining a first conversion relation according to a preset strategy, representing overlapped edges of adjacent surface patches by using the same coordinate data according to the first conversion relation to obtain a processed surface patch set, and determining a three-dimensional model of a to-be-reconstructed object according to the processed surface patch set, with the first conversion relation comprising a conversion relation of each edge in voxels. The problem that more storage resources are occupied is solved, and reconstruction of the three-dimensional grid is achieved.

Description

technical field [0001] The present application relates to the field of three-dimensional scanning, in particular to a three-dimensional mesh reconstruction method, device, electronic device and storage medium. Background technique [0002] The most important part of a 3D scanner is the camera. When scanning, the 2D image information is obtained through the camera, and then the 3D information is reconstructed. Before reconstructing the 3D information of the object, it is usually necessary to generate a surface grid on the surface of the object, and then use the surface grid The 3D information of the object is reconstructed based on the grid. [0003] The existing surface mesh generation methods need to regenerate all the surface mesh information every time the scanning data is updated, which requires more storage resources and computing resources. [0004] Aiming at the problem that storage resources and computing resources are occupied in related technologies, no effective ...
