Abstract

The invention provides a real-time three-dimensional model reconstruction method and system based on a deep video stream. The method comprises the following steps: constructing shooting devices; collecting depth information and color information through the shooting devices, and carrying out distortion correction processing on the depth information and the color information; carrying out feature matching on the depth information and the distortion information obtained after distortion correction processing, and carrying out spatial matching processing, fusing the depth information shot by eachshooting device into one point cloud model, and carrying out feature matching and cropping on images in timestamp synchronization of each shooting device; carrying out triangular facet calculation processing and optimization processing on the point cloud information to generate an information group with a time label; and through a three-dimensional reconstruction computer, obtaining the information group, carrying out time matching and fusion on model information sent by the plurality of shooting devices to realize three-dimensional reconstruction and carrying out adjustment and display according to calibration parameters. The method and system reduce three-dimensional reconstruction consumed time by adopting the mode of unification of the depth and color and resampling frame reduction and triangular facet optimization.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a real-time three-dimensional model reconstruction method and system based on depth video streams. Background technique [0002] The 3D model reconstruction based on the depth camera is an important part of the automatic modeling of real objects and the application of virtual-real fusion. At present, fine 3D modeling requires expensive equipment and complex processing, and can only generate static models; while cheap depth cameras can only generate blurred scenes, which are far from meeting the needs of virtual-real fusion. Contents of the invention [0003] The aim of the present invention is to solve at least one of said technical drawbacks. [0004] Therefore, the purpose of the present invention is to propose a real-time 3D model reconstruction method and system based on depth video stream. [0005] In order to achieve the above object, an embodiment of...
