Fast Optimization Algorithm for Camera Exposure Time Based on ZYNQ
In the process of high-speed camera image acquisition,the accuracy and speed of automatic exposure con-trol will have a significant impact on the camera image quality.This paper deeply studies the mathematical relation-ship between image entropy and exposure time,and uses the ZYNQ platform to implement a fast exposure time opti-mization algorithm.The key module timing simulation experiment results and imaging experiment effects are intro-duced.The experimental results show that this method can converge to a suitable exposure time within 11 frames under the conditions of front light,back light and side light.It meets the requirements of detection equipment for re-al-time and environmental adaptability.
