Abstract

The embodiment of the invention discloses a multi-view image texture distribution determination method and device, equipment and a storage medium, and the method comprises the steps: determining eachtriangular patch according to a set triangular grid model, and obtaining a multi-view image corresponding to each triangular patch; Respectively calculating the target weight of each image corresponding to the triangular patch, and determining the target image corresponding to each triangular patch; Traversing each node of the undirected graph, and updating the node information of the current nodeaccording to the node information of the adjacent node of the current node; Wherein the node information of the adjacent node and the node information of the current node respectively comprise a nodevalue and a label, the node value comprises a target image corresponding to a triangular patch of the node, and the label comprises a target image meeting a set condition in the target image; And determining the texture distribution of the triangular patch of the triangular mesh model according to the updated node information of the current node. The texture quality during reconstruction of a natural scene in the multi-view image is improved, and the texture mapping effect is enhanced.

Description

technical field [0001] Embodiments of the present application relate to 3D model reconstruction technology, and in particular to a method, device, device and storage medium for determining texture distribution of multi-view images. Background technique [0002] With the rapid development of 3D reconstruction related technologies, the reconstruction of high-precision 3D models of natural scenes from multi-view images has become more and more mature, but to achieve a realistic display of natural 3D scenes, it is not enough to restore their 3D geometric models , it is also necessary to restore the true texture of its surface. Therefore, how to effectively paste real textures on the reconstructed 3D model is also a topic worthy of attention. [0003] Multi-images provide a rich source of texture data for texture mapping, and the triangular patches on the surface of the model are visible in images from multiple perspectives. However, when multi-images are directly used as model ...
