摘要：In order to solve the problems of overexposure or underexposure that are easily encountered when reconstructing a strong reflective surface in visual measurement, we propose an automatic multiple exposure surface structure light measurement method. The core of this method is to calculate the camera response curve according to the variation of the reference point pixel value with the exposure time. Using camera response curves and images at different exposure time, we calculate the numbers of exposure and exposure time required for the current scene measurement. Image sequences with different exposure time are fused into a new fringe image sequence for reconstruction. The experimental results show that the method can accurately calculate the time of each exposure and overcome the problem of saturation or oversaturation of the fringe image caused by the strong reflection surface, and realize the three-dimensional optical non-contact measurement of the object with high dynamic range surface reflectivity. © 2018, Chinese Lasers Press.
