Abstract

Abstract:

In view of the requirement of image quality, integration level and real-time application of the imaging systems under fog weather, this paper reports a polarization imaging system with a dehazing ability. The differential signal is converted by FPGA, and a highly integrated CMOS imaging circuit is built based on the internal PLL of the image sensor and the CamLink protocol. The obtained image is inversed by stokes equations, and the real-time dehazing algorithm is realized by the built-in DSP module. The total size of the polarization imaging system is 117mm×117mm×126mm, and the weight of the system is 1.2kg. An imaging experiment was made under fog weather, and the dehazing ability of the imaging system is proved by the contrast of the original image and the dehazed image's histogram and RGB distribution. Experimental results show that the imaging system can stably obtain a color dehazed image at 2048×2048@180Hz.
