基于准不动点集的高速铁路前向运动视频区域划分方法

为保障高速铁路行车安全,以快速检测高速铁路沿线运行环境为背景,建立了基于高速前向运动视频的环境检测模型,并提出人工干预的前向运动视频全景图拼接方法.该模型包括高速前向运动视频区域划分、全景图拼接等.为实现前向运动视频区域自动区域划分,本文提出一种基于准不动点集的前向运动视频消失点定位方法,结合铁路线路的先验信息可实现前向运动视频区域自动划分.实验结果表明:该方法是一种无需人工干预的快速自动划分方法,为铁路前向运动视频全景图全自动拼接提供参考.

Region partition method for high-speed railway forward-looking motion video based on quasi-fixed point set

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.
