摘要：
Dear Editor, In order to realize the pixel level light adjusting control of the binocular high dynamic light adjusting and imaging system, this letter proposed a novel self-calibration method. By analyzing the optical design of the system, the causes of the distortion are given and a distortion model is established. Then, a quick and accurate self-calibration method is designed. The experiments indicate that the method can calibrate the two image sensors of the system at the same time, the average pixel deviation of the calibrated system is less than 0.5 pixels and the maximum deviation is less than 1 pixel. This method does not need external calibration template and its precision can satisfy the requirement of the system.
