摘要
在接收实时下传的视频图像时,需要实时生成相应的视频拼接图像。针对这一问题,通过对接收视频进行采集,得到有一定重叠区域的视频图像序列,应用改进的基于特征区域的特征提取匹配法对重叠图像进行快速配准,采用渐入渐出融合算法消除拼缝,实现无缝大视场拼接。工程应用表明,该方法可以自动对视频图像(25帧/s、帧格式为768×576)进行拼接,满足系统实时拼接的要求。
In receiving real-time video, mosaic imaging shall be generated in real time. In order to solve this problem, video was collected in real-time to get overlapped images. The overlapped images were rapidly registered using the improved distilling and matching character method, and the gradated in-and-out amalgamation algorithm was applied to eliminate the seam and to get a seamless and wide field of view image. The test results show that the system can automatically stitch the overlapped images with the speed of 25FPS and resolution of 768 ＊ 576, and the real-time property of system is satisfied.
