Title:
THREE-DIMENSIONAL RECONSTRUCTION METHOD, APPARATUS, AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/001168
Kind Code:
A1
Abstract:
Disclosed are a three-dimensional reconstruction method, apparatus, and device, and a storage medium. The three-dimensional reconstruction method comprises: determining a relative camera pose of a current depth image key frame with respect to a preset depth image key frame by using a preset fast global optimization algorithm; determining at least one effective space block corresponding to the current depth image key frame by using a sparse sampling method; fusing the at least one effective space block with a first three-dimensional grid model corresponding to a previous depth image key frame on the basis of the relative camera pose, to obtain a second three-dimensional grid model corresponding to the current depth image key frame; and generating an equivalent contour surface of the second three-dimensional grid model by using an accelerated marching cubes algorithm, to obtain a three-dimensional reconstruction model of a target scene.
