Human body surface reconstruction method in three-dimensional reconstruction

Abstract

The invention discloses a human body surface reconstruction method in three-dimensional reconstruction, and the method comprises the steps: carrying out the three-dimensional data collection of a human body standing on a turntable through employing a fixed Kinect device, carrying out the registration and fusion of collected point cloud data at multiple angles, and obtaining a complete human body three-dimensional contour; carrying out downsampling on the human body contour point cloud data; and adopting a greedy triangularization algorithm to carry out triangular surface generation on the point cloud to obtain a rough human body gridding model, carrying out color mapping on the generated triangular surface by using color information of three vertexes of the triangular surface to generate human body surface textures, and acquiring a complete human body three-dimensional model with real texture information. The fixed Kinect equipment is used for collecting human body information, so thatreconstruction errors are reduced. ..Actual color information is added to the human body model by adopting a triangular point cloud color mapping method, the surface detail characteristics are enhanced, a better human body three-dimensional reconstruction effect can be obtained, and the sense of reality of human body modeling is improved.

Description

technical field [0001] The invention relates to a human body surface reconstruction method, which can improve the sense of reality of human body modeling, and belongs to the technical field of data processing. Background technique [0002] With the continuous development of 3D reconstruction technology, in computer vision, virtual reality and other fields, obtaining object contour information and 3D modeling, 3D reconstruction technology has important applications, and the acquisition of human body contour information has more important significance. [0003] At present, the system for obtaining 3D models is large in size and expensive, and the traditional human body modeling process usually needs to paste marker points, which is cumbersome and complicated.

Problems solved by technology

[0003] At present, the system for obtaining 3D models is large and expensive. The traditional human body modeling process usually needs to paste marker points, which is cumbersome and complicated.

[0004] The 3D human body reconstruction method based on the Kinect device can easily obtain human body surface data, but the results obtained by the existing methods are not complete enough, and the equipment collected during the reconstruction process needs to be moved, which introduces errors into the subsequent reconstruction process, and the reconstruction results are the same as There is a large error in the real human body size, the obtained human body model is not very realistic, and the surface details are not clear enough, which reduces the realism of human body modeling
