摘要
为了实现基于PC机的实时视频拼接,提出一种基于自适应匹配的平移参数计算方法。设计基于海思HI3520D开发平台采集两路视频,UDP传输视频,PC机接收视频并实现视频拼接。在系统启动时候,通过巴氏距离方法得到融合后的图像重叠区域匹配度,反馈优化,得到最佳平移参数。试验证明该系统不仅提高了图像融合质量而且具有良好的实时性,实现了两路视频实时拼接,系统总体拼接速度为40 ms左右。
In order to implement real-time video stitching based on PC, a kind of calculation method based on adaptive matching translation parameters is put forward. Design based on HI3520D development platform to collect two way video, UDP transmission video, PC receives the video and realizes video stitching. In the system boot time, through the Bhattaeharyya Distance method to get the fused image overlap matching degrees, feedback optimization, get the optimum parameters of the translation at the system boot time. Experiments prove that the system not only improves the quality of image fusion and has good real-time performance, has realized the real-time video stitching, system overall stitching at the rate of about 40 ms.
