    Abstract

    A method for fast capturing three-dimensional shape and color texture with the black and white camera was proposed based on the absolute phase measuring and active color lighting. First, two stripes with 1/3 period phase shift and one stripe whose period is slightly different with the two stripes are projected. The deformed stripes are captured simultaneously. Then, patterns with the specific color of white, red and green are projected on the objects respectively and the images are captured. Second, by using the fourth image, the first and the second deformed stripes, phase distribution of the stripe is obtained with improved phase shifting method. The phase distribution of the other stripe is obtained with improved Fourier transform method by using the fourth image and the third deformed stripe. Then, the absolute phase distribution is obtained. Finally, by using the fourth image, the fifth and sixth image, the reflected green component of scene is obtained. According to the principle of the colorimetry, the color texture of scene is retrieved. The experimental results show that the high quality color texture and the high measurement accuracy for three-dimensional shape can be achieved simultaneously with the proposed method. The recording speed of the three-dimensional data and the color texture can reach to 30 fps.
