【 摘 要 】

Aiming at the existing problems of low real-time performance, unsatisfactory stitching effect and high cost in video stitching system at present, a real-time video stitching system was implemented on Xilinx Zynq platform using software and hardware collaborative design method after improving traditional ORB algorithm. The system used PS on Zynq to build an embedded Linux system, develop user interface programs, and implement task scheduling. The improving video stitching algorithm was packaged into an IP core that can be deployed into the PL on Zynq through Vivado HLS tools to achieve hardware accelerated processing. Experimental results showed that stitched video image had high clarity and no stitching gap, while this Zynq-based software and hardware collaborative processing architecture had greatly improved the speed of video stitching, which can meet the requirements of real-time processing.
