摘要
针对当前多路视频拼接系统实时性差、拼接效果不理想的问题,提出一种DSP+PC构架的视频拼接系统。该视频拼接系统由普通的PC机和硬件加速卡组成,硬件加速卡实现视频采集和视频拼接融合功能,PC端主要负责视频显示和人机交互,它们两者之间通过PCIe高速协议进行数据传输。此外,论文通过改进基于SURF的特征点提取算法,提高了数据处理速度和配准精度。该设计实现了8路标清视频的实时拼接与显示,并显著提升了视频拼接效果。
In order to deal with the problem that multichannel video mosaicing system has worse real-time performance and unsatisfactory stitching effect,a video mosaics system of DSP + PC architecture is presented.The video mosaicing system is composed of ordinary PC and the hardware acceleration card.The hardware acceleration card is really to realize the function of video capture and video fusion splicing,and PC is responsible for video display and human-computer interaction.The data transmission between PC and hardware acceleration card relies on the PCIe high-speed protocols.In addition,through improving the feature points extraction algorithm based on SURF(Speeded Up Robust Feature),the data processing speed and matching accuracy is improved.The design has realized the 8sign clear video stitching and display in real time,and significantly increased the video stitching effect.
