Method for reconstructing object surface and device thereof and computer storage medium

Abstract

The invention discloses a method for reconstructing an object surface and a device thereof and a computer storage medium, and the method comprises the steps: generating a corresponding dense point cloud through a plurality of images, and the plurality of images can be obtained through photographing a scene from different photographing position points; based on the dense point cloud, generating a tetrahedral mesh corresponding to the dense point cloud, the vertex of each tetrahedron in the tetrahedral mesh being a coordinate point in the dense point cloud; generating a binary label for each tetrahedron based on energy function minimization, the binary labels being used for representing that the tetrahedrons are located inside or outside the surface of the object; and extracting a common surface between the tetrahedrons with different binary labels to reconstruct the surface of the object. The energy function comprises the sum of first penalty terms corresponding to the tetrahedron and the sum of second penalty terms corresponding to the common surface, and the second penalty terms comprise grid density weights. Through the above mode, the negative influence of the noise points on the surface details of the reconstructed object is reduced, and the reconstruction precision is improved.
