A 3D scene generation method based on depth video

Abstract

The invention discloses a 3D scene generation method based on a depth video. The method comprises the following steps that S1, data of the depth video and a color video are collected by using a depth camera, and filtering out is performed; S2, the depth video on which filtering out is performed is converted into three-dimensional point cloud data by combining a plane coordinate and a depth value, and then a scene model is built according to the three-dimensional point cloud data; S3, the color corresponding to each point in the three-dimensional point cloud data is obtained from color video data on which filtering out is performed and the color is applied to the scene model so as to obtain a color scene model; S4, the format of data of the color scene model are converted into the 3D file format, and converted files are 3D scene files. The scene generated through the method is verisimilar and natural, modeling is convenient and efficient, calculation amount and memory space are small during drawing, and the method is more suitable for real-time modeling and drawing.

Description

technical field [0001] The invention relates to the field of computer graphics and image processing, in particular to a 3D scene generation method based on depth video. Background technique [0002] For a long time, computer workers have been pursuing the use of computers to construct realistic virtual 3D scenes, and 3D scene modeling has always been one of the most active research fields in computer graphics and image processing. [0003] In traditional scene modeling, geometry-based modeling methods are usually adopted. This method usually uses the existing 3D modeling software to manually model the scene, mainly through the superposition of 3D models to construct the scene. The constructed scene has high precision, complete model description and good interaction. But the shortcomings are also very prominent, that is, the workload of human-computer interaction is huge, which leads to low efficiency of modeling; it is also easy to greatly reduce the authenticity of the sce...
