Title:
THREE-DIMENSIONAL RECONSTRUCTION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/051783
Kind Code:
A1
Abstract:
The present disclosure relates to a three-dimensional reconstruction method and apparatus, and a device and a storage medium. The three-dimensional reconstruction method comprises: acquiring a plurality of images to be reconstructed of a target object (S210); performing feature matching on the basis of extracted feature data of the plurality of images to be reconstructed, so as to obtain a first matching result of the plurality of images to be reconstructed (S220); according to the first matching result, constructing a graph structure between a plurality of target images to be reconstructed among the plurality of images to be reconstructed (S230); and performing three-dimensional reconstruction on the basis of the graph structure, so as to obtain a first reconstruction result of the target object (S240), wherein the first reconstruction result comprises three-dimensional data of the target object. In the method provided in the present disclosure, the plurality of images to be reconstructed of the target object are acquired by means of a movable terminal with a camera function, and the three-dimensional reconstruction of the target object is completed on the basis of the plurality of images to be reconstructed, thereby simplifying operation procedures, reducing device costs and having a better three-dimensional reconstruction effect.
