Abstract

Embodiments of the present invention provide a three-dimensional reconstruction method. The method includes: creating an initial three-dimensional point cloud of the first image based on the first image and a first depth map corresponding to the first image; re-projecting the initial three-dimensional point cloud to a common view to obtain image coordinates, and judging whether the initial three-dimensional point cloud is visible in the common view; if the initial three-dimensional point cloud is visible in the common view, fusing the initial three-dimensional point cloud and the image coordinates to obtain a three-dimensional reconstruction model. The method of the invention optimizes the three-dimensional point cloud through the common view, and fuses the optimized three-dimensional point cloud and the initial three-position point cloud, thereby obtaining dense three-dimensional point cloud data for realizing the three-dimensional reconstruction with high accuracy, improving the accuracy of the three-dimensional reconstruction and reducing the cost of the three-dimensional reconstruction.

Description

technical field [0001] Embodiments of the present invention relate to the field of software technology, and more specifically, embodiments of the present invention relate to a method, medium, device, and computing device for three-dimensional reconstruction. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] There are two main types of methods for generating 3D information of objects in virtual environments such as computers: one is to use geometric modeling software to generate 3D geometric models of objects under human control through human-computer interaction, and the technical realization of this type of method has been very Mature, such as 3DMAX, Maya, AutoCAD, UG and other software support this technology, these software generally use curves and surfaces with mathema...
