Abstract

Three-dimensional (3D) measurement of colorful objects is challenging. As different colors can absorb different wavelengths of projected light, the brightness and contrast of the captured fringe are not uniform when employing single-color light projection, which will lead to measurement error. In this paper, we present a rapid 3D measurement technique for colorful objects employing red, green, and blue (RGB) light projection. According to the research in this paper, for common colors, the pixel with the largest brightness and contrast can be extracted from the three fringes projected by RGB light. Furthermore, we introduce the selection method of exposure time, and then combine the high-speed projection technique with the optimal pixel-extraction algorithm to get the optimal set of fringes for phase calculation. Experiments show that the proposed method improves the measurement accuracy and efficiency.
