Title:
THREE-DIMENSIONAL RECONSTRUCTION METHOD, THREE-DIMENSIONAL RECONSTRUCTION APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/088799
Kind Code:
A1
Abstract:
A three-dimensional reconstruction method, a three-dimensional reconstruction apparatus and a non-transitory computer-readable storage medium. The three-dimensional reconstruction method comprises: acquiring a plurality of input images that comprise a target object, and acquiring a plurality of first position coordinates, in a geodetic coordinate system, of an image acquisition apparatus corresponding to the plurality of input images; constructing a reconstruction coordinate system on the basis of the plurality of input images, and performing three-dimensional reconstruction processing regarding the target object according to the reconstruction coordinate system, so as to obtain a first three-dimensional reconstruction model of the target object and a plurality of second position coordinates, in the reconstruction coordinate system, of the image acquisition apparatus corresponding to the plurality of input images; and on the basis of the plurality of first position coordinates and the plurality of second position coordinates, performing transformation processing on at least some points in the first three-dimensional reconstruction model, so as to obtain a second three-dimensional reconstruction model.
