基于准不动点集的高速铁路前向运动视频区域划分方法
Region partition method for high-speed railway forward-looking motion video based on quasi-fixed point set
摘要
Abstract
In order to ensure the safety of high-speed railway,a new railway running environment inspection model based on high-speed forward-looking motion video has been established,and a panorama stitching approach has been proposed with human intervention.The model includes the region partition and panoramic stitching.In order to achieve automatic partition in the high-speed forward-looking motion video,this paper proposes a novel method for locating vanishing point of the forward-looking motion video based on quasi-fixed point set,which can be combined with the priori information of the railway line,we can realize automatic partition of the forward-looking motion video.The experimental results show that this method is a fast automatic method without manual intervention,which lays a foundation for automatic panorama stitching of railway forward-looking motion video.关键词
