摘要	For the distortion caused by a secondary incline in optical design for a high dynamic dimming imaging system based on Digital Micromirror Device(DMD), this paper establishes a self-distortion correction model based on regioning. According to the optical path design characteristics of the high dynamic dimming imaging system, the reasons of distortion were analyzed. By taking the causes and features of different types of distortion models into account, a model was established based on distortion correction function region by combination with the characteristics of the system itself. To solve the problems of over-assignment or un-assignment in correction processing, a reverse correction method was used to solve the distortion parameters and to complement the distortion correction. Finally, the self-projection by DMD was used to calibrate the displaying template and to realize the design of self-distortion correction system. The experimental results show that the pixel error of system after correction is 0.87 pixel. As compared with the traditional correction model, the model overcomes the slope distortion, radial distortion and the eccentric distortion and the distortion correction process does not depend on external environment, so it has fast and reliable correction procedure and meets the requirements of high dynamic dimming imaging systems. 2015, SCIENCE PRESS.
