Abstract

The present invention discloses a real-time reconstruction method for a three-dimensional scene based on a depth camera. The method comprises the following steps: acquiring original depth data and color data, performing denoising processing on the depth data, performing coordinate conversion on a depth image, performing camera attitude tracking, performing point cloud fusion and recording color information, performing point cloud model implicit surface rendering, and performing scene model reconstruction. According to the method disclosed by the present invention, the scene is scanned by usinga single depth camera, a depth data stream of the scene is obtained, real-time processing is performed on the data on the computer, and a corresponding three-dimensional model is generated; and a three-dimensional reconstruction system with a low cost, an easy operation, high quality and real-time performance can be provided, and a three-dimensional model with high quality and strong visualization is generated.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a method for real-time reconstruction of a three-dimensional scene based on a depth camera. Background technique [0002] Three-dimensional reconstruction technology refers to capturing the shape and appearance of real objects, establishing corresponding mathematical models, and processing, operating and analyzing them in the computer. In the fields of computer graphics and computer vision, 3D reconstruction technology is a common method to solve 3D modeling problems, and it has very important practical significance for 3D realistic modeling and large-scale complex scene modeling. With the continuous update and development of computer hardware and depth data acquisition equipment, 3D reconstruction technology has been widely and deeply applied in the fields of movies, games, auxiliary medical treatment, urban planning and so on. [0003] According to the...
