Fusion of Color Photometric Stereo Method and Slit Pattern Projection Method to Measure Three-Dimensional Shapes of a Human Face

We propose a new method for measuring three-dimensional (3D) moving facial shapes. This method uses photometric stereo method and slit pattern projection method with color light sources. The time required for sampling data can be reduced by switching the color light rays at high speed, and hence a series of 3D shapes of a moving human face at each instant can be measured. Experimental results are shown to demonstrate the feasibility of the proposed method.
