METHOD FOR CONSTRUCTING THREE-DIMENSIONAL REAL-SCENE MODEL, AND RELATED APPARATUS

WIPO Patent Application WO/2023/280038

A1

Disclosed in the present application is a method for constructing a three-dimensional real-scene model, which method is applied to an electronic device. The method in the present application comprises: acquiring a first correlation between a sub-image in a satellite image and a building plane in a three-dimensional model; acquiring a first image, wherein the first image comprises an image of the building plane, the first image is obtained by means of photographing from the ground, and the resolution of the first image is higher than that of the sub-image; matching the first image with the sub-image to obtain a second correlation between a first region and a second region, wherein the first region is a region in the first image that represents the building plane, and the second region is a region in the sub-image that represents the building plane; and executing texture mapping on the building plane in the three-dimensional model according to the first image and on the basis of the first correlation and the second correlation, so as to obtain a three-dimensional real-scene model. On the basis of the method, a three-dimensional real-scene model having a high texture resolution can be obtained, thereby improving the precision of the three-dimensional real-scene model.
