A three-dimensional measurement method based on three channel binary fringe defocused projection is proposed in this work. The phase-shifting fringes are encoded into three color channels. At the projector, the binary digital images separated from three channels are used as input. The defocusing fringes of three channels are projected sequentially in a single camera frame time, and the fusion color fringe images of three channels are obtained by color camera. The color three channel fringes are decoupled and the aliasing effect of color channels in the measurement system is calibrated with a black and white camera. Phase calculation and three-dimensional reconstruction are performed based on decoupled fringe information. The results suggest that compared with the traditional color projection measurement, the speed and rebuilding accuracy of the proposed method are greatly improved, and the proposed method is suitable for measuring color objects and dynamic objects.
