| 摘要: |
| 提出一个快速的三维彩色全身人像捕捉系统（名为化身1号）：1.5s采集数据，1min内全自动地建立三维全身人像.化身1号使用了8台自制的结构光扫描仪，采集数据的精度达到1mm.这8个扫描仪预先配置好空间位置：4个抓拍头部，4个抓拍身体.从而能够有效地覆盖采集成人对象的全身区域.在离线标定完8个扫描仪后，化身1号就可以捕获真实对象，在一个坐标系内处理各扫描仪采集的局部数据，历经全局注册和无缝隙的纹理拼接，鲁棒地建立高逼真度的纹理人像模型.该模型的几何精度达到1mm，并具有照片真实感的色彩信息.实验结果表明，在高逼真度建模需求的前提下，化身1号的采集和处理速度均处于当前最优水平. |

| Abstract: |
| This article presents a fast 3D color full-body capture system, named Avatar 1, which can scan a subject in 1.5 seconds and automatically provide the full-body model within 1 minute. It uses eight self-made structure-of-light scanners which are built based on structured lighting technique and have a measuring accuracy of 1mm. The eight scanners are configured to effectively cover the full-body surface of an adult, four scanners are arranged to capture the head, while four target the body. After calibrating the scanners in the offline step, it can capture the real subject and process all partial scanned data in the same coordinate. Through the global registration and seamless texture stitching steps, it robustly reconstructs a high-quality full-body textured model, which has 1mm geometric accuracy and photo-realistic color information. The experiments demonstrate that Avatar 1 achieves state-of-the-art scanning and processing speed under high-quality result requirement. |
