摘要
实现了基于Xilinx XC6SLX45 FPGA的高清实时视频去雾系统,详细介绍了系统的逻辑框架及主要的算法实现。首先,介绍了整个系统的硬件框架及FPGA内部的逻辑框架;其次,描述了改进的暗原色先验去雾算法,给出了在FPGA中的算法实现过程;最后,对系统进行测试。实验结果表明,该系统实现了预期的高清视频实时去雾,并具有自适应功能,去雾效果良好。
Design and implementation of high-definition real-time video dehazing system based on Xilinx XC6SLX45 FPGA are in- troduced in this paper. The overall architecture of the system and algorithm are described in detail. At first, hardware architecture of the system and logic architecture inside FPGA are introduced. Secondly, improved dark channel prior haze removal algorithm is contributed with the algorithm implementation in the FPGA. Finally, the result shows that the system works as expected with the a- daptive function. The system has good real-time performance and dehazing effect for high-definition haze video.
