Abstract

The invention relates to a three-dimensional real-time capture system without marking points for performers. The steps include: 1) The establishment of a room-type acquisition hardware system: by analyzing the parameters of the camera, a configuration model of a multi-eye RGB-Depth camera is proposed. The viewing angle range of the multi-eye camera can effectively cover the performer; collection room. 2) Global registration of multi-eye RGB-Depth cameras. Through pairwise registration and global optimization of cameras, the corresponding relationship between point cloud models on different coordinate systems of different RGB-Depth cameras is established. 3) Real-time performance capture. Using the GPU-accelerated Poisson surface reconstruction algorithm, the dense point cloud captured by the multi-eye RGB-Depth camera is processed in real time, and the real-time reconstruction of the dynamic 3D mesh model sequence is completed. This system does not need markers, and uses a low-cost RGB-Depth camera. The system can capture and reconstruct the dynamic 3D information of the performers in real time, and establish a corresponding dynamic 3D geometric model.

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, but also Have individual posture characteristics. ...
