The Research Of Three-dimension Face Reconstruction System

The research of the three-dimension face reconstruction system can be applied in the field of three-dimension face recognition, medicine, real three-dimension model simulation, virtual reality and so on, the future of which is very wide. The research activity of this paper covers from theory analysis, algorithm analysis and implementation to the design of the system implementation plan, which ranges from all the aspects of the three-dimension face reconstruction system.First of all, this paper investigates, concludes and compares the current technologies in the field of three-dimension information retrieval both domestic and abroad. Then it presents the generation method of sine time-domain phase-shift raster, and also it analyses the output result of the experiment. After that, the thesis analyses the core step of this system ~ phase unwrapping in detail, and then suggests a phase unwrapping algorithm based on two-eyes and phase connection algorithm. The following paragraph of the thesis focuses on the calibration of the system because some formula way introduced before can only get the exact depth information in theory, but not in real system. The calibration method includes the camera calibration and project calibration, also the paper mentions some notice when using calibration board. At last, this paper presents the system design plan.
