Abstract

The invention relates to a marker-free three-dimensional real-time capture system for a performer. A method includes the steps that (1), room type collecting hardware system building: an allocation model of multi-view RGB-Depth cameras is provided through analysis of camera parameters, the performer is effectively covered with the viewing angle range of the multi-view cameras, and then a room type sealed collecting room is built; (2), overall situation registration is performed on the multi-view RGB-Depth cameras, and corresponding relations between cloud models of all points, in different coordinate systems, of the different RGB-Depth cameras are built through pairwise registration and overall optimization of the cameras; (3) real-time performance capturing. A Poisson surface rebuilding algorithm accelerated by a GPU is used for processing dense point clouds captured by the multi-view RGB-Depth cameras in real time and completing real-time rebuilding of a dynamic three-dimensional grid model sequence. Markers are not needed, and the system can capture and rebuild dynamic three-dimensional information of the performer in real time and build a corresponding dynamic three-dimensional geometrical model by using the low-cost RGB-Depth cameras.

Description

technical field [0001] The present invention belongs to the field of general image data processing, focuses on the three-dimensional capture of performers, and involves capturing the form (shape and posture) of performers in real time without using marker points, and reconstructing the corresponding dynamic three-dimensional model sequence . Background technique [0002] Capturing the 3D form of performers is an important issue in the field of image data processing, a key technology for reconstructing realistic dynamic 3D model sequences, and an important basis for many application problems such as 3D reconstruction and processing of performers. [0003] Performance Capture refers to capturing the form (shape and posture) of the performer through the camera, and creating a dynamic 3D model of the performer in the computer virtual scene. The reconstructed model not only has the realistic individual shape of the performer, And it has individual posture characteristics. [00...
