Abstract:This article presents an algorithm to avoid camera overexposure or underexposure by calculating and analyzing the camera response function. First, the range of intensity value and time is set to ensure that the intensity value of each image pixel is within the measurement range when the camera's exposure time is within the time range. Then, the reference image which has the maximum number of pixel intensity values within the intensity value range is selected. Third, the camera response function will be calculated based on the variation of the reference point intensity value with the exposure time. Finally, the whole exposure times will be recovered based on the computed response function, and used in the process of structured light measurement. The experimental results verify the performance and feasibility of the proposed method. © 2018 SPIE.
