首发时间:2016-01-19
摘要:本文提出了一种基于高速铁路前向运动视频的全景图自动拼接算法。该算法首先根据高速铁路视频中的场景几何特性,检测场景中的线段及消失点,从而生成场景的空间布局关系;在此基础上,自动构建合适的采样区域,以达到无缝拼接的效果;最后实现全景图的自动拼接。实验结果表明,该方法与手工确定采样区域的方法相比,具有速度快,拼接效果更准确的优点。

Research on automatic stitching algorithm of panoramic image based on high speed railway forward motion video
Abstract:The paper presents an automatic panoramic image stitching algorithm based on high speed railway forward motion video. According to the scene geometry properties of high speed railway in video, the algorithm firstly detects line segments and the vanishing point. And then we automatic construct the appropriate sampling area to achieve seamless splicing. Finally, we realize automatic panorama stitching. The experimental results show that compared with the manual method to determine the sampling area, our algorithm is faster and more accurate.
Keywords: panorama vanishing point image fusion automatic splicing speed estimation
