1. A point cloud model reconstruction method, implemented in an encoder and comprising:
obtaining an i-th segmentation position of an i-th three-dimensional slice on a longest edge in a point cloud space, 1≤i≤n−1 and n being a total number of three-dimensional slices to-be-processed;
determining an i-th cube block set nearest to the i-th segmentation position in the i-th three-dimensional slice based on the i-th segmentation position and a preset cube block length;
determining, along the longest edge, an i-th vertex position with a cube block in the i-th cube block set, the i-th vertex position representing a position of a vertex on an edge which is away from a start position of the cube block by the preset cube block length; and
reconstructing a point cloud model based on the i-th vertex position.
