| Summary: | In order to ensure the real-time performance of the system and solve the problem that the perfect reflection method fails in the exposure environment, this paper proposes an FPGA-based dark channel automatic white balance correction algorithm. According to the light transmittance distribution of the dark channel of the color image, the reference pixels are selected to realize the automatic white balance correction of the color cast pixels. Experimental results show that the dark channel automatic white balance algorithm using FPGA correction can meet the real-time requirements of the entire system and eliminate the environmental impact of overexposure. At the same time, it can be effectively applied to dynamic scenes.
