3D Facial Data Acquisition and Reconstruction System
三维面像数据采集和重建系统

A laser-based active triangulation 3D information acquisition and reconstruction system is presented in this paper. This system can not only obtain the whole 3D data of object surface but also get rid of the missing problem. The measurement principle, calibration and reconstruction are described in details. The experiments demonstrate that the precision is 0.3mm with the 1m range. This method has the properties of hign accuracy, simple calibration and computation and wide application prospect.
