Kind Code:

A1

Abstract:

Provided are a grid generation method and apparatus, an electronic device, a computer-readable storage medium, a computer program, and a computer program product. The grid generation method comprises: determining a voxel corresponding to a pixel in a preset voxel space on the basis of an image coordinate and a depth value of the pixel in a current depth image (S120); determining structured data increment information corresponding to neighborhood voxels on the basis of the neighborhood voxels of the voxel and the structured data corresponding to the previous depth image (S130); and finally, generating a target grid corresponding to the current depth image on the basis of the structured data increment information corresponding to the neighborhood voxels (S140). Based on the structured data increment information corresponding to the voxel, the grid is extracted, the target grid is generated instead of extracting the grids for all the structured data, the calculation amount of grid extraction can be reduced, the time consumption of grid extraction is reduced, and the grid extraction efficiency is effectively improved.
