Abstract：Color coded structured light based on De Bruijn sequence is a kind of spatial code method that is characterized by rapid shape measurement. The recognition of color stripes is a key issue. Considering projected De Bruijn stripe pattern combining four colors with high and low intensity, segmentation of high and low intensity stripes was implemented by using linear filter of second derivative of L channel in L*a*b* color space. Adaptive color clustering was designed by employing Principal Component Analysis (PCA) and K-means clustering. The recognition of four colors with two intensities was finished. The experimental results indicate that the proposed method is robust to factors such as ambient light and it satisfies demand for high precision and simple extraction of information to structured light vision measurement.
