Abstract

The embodiment of the invention discloses a curved-surface reconstruction method and device. The method includes: acquiring a point cloud corresponding to an image, wherein pixel points in the image correspond to points in the point cloud one by one; arranging the points in the point cloud according to positions of all the pixel points in the image to obtain a point cloud matrix corresponding to the point cloud; and constructing a first preset number of triangular meshes, which correspond to each point, in the point cloud matrix, and splicing all the constructed triangular meshes into a targetcurved-surface. Therefore, according to the scheme, a three-dimensional surface function does not need to be obtained by solving, a process is simple, a calculation amount is low, and curved-surfacereconstruction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a curved surface reconstruction method and device. Background technique [0002] Three-dimensional reconstruction (3D Reconstruction) refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. key technologies. [0003] In the process of 3D reconstruction, surface reconstruction is a very important part. At present, most surface reconstruction schemes are surface reconstruction based on RGBD (fusion of RGB image and depth image information) point cloud. The solution mainly includes: convert the RGBD data collected by the depth camera into an RGBD point cloud, then calculate the normal vector of each point in the point cloud, and obtain a very complex three-dimensional surface according to the three-dimensional coordinates and normal vector of each point function, according to which a triangular ...
