基于轨道环境特征的轨道环境识别

Orbits Environment Recognition Based on The Environmental Characteristics

随着高速铁路的建设与发展,铁路运输以其距离长、速度快、载运能力强的特点,成为了本国不可或缺的基础交通工具,铁路运输的安全越来越受重视。对铁路环境激光雷达点云数据进行点云分割及数据分析,实现导轨、接触线和承力索目标的分类识别,这对保障铁路运输安全具有重要的实际意义。基于对其环境特征的研究,检查目标对象的相关特征,并且利用区域增长、近邻分析等方法对轨道、接触线及承力索进行分类,提出了针对轨道环境的约束条件。

With the construction and development of the idle railway,railway transportation has become an indispensable basic vehicle in the country because of its long distance,fast speed and strong carrying capacity.The safety of railway transportation is receiving more and more attention.In this paper,the point cloud segmentation and data analysis of the laser environment point cloud data of the railway environment are carried out to realize the classification and identification of the guide rail,the contact line and the bearing cable target,which has important practical significance for ensuring the safety of railway transportation.Based on the study of its environmental characteristics,the relevant characteristics of the target object are examined;and the orbits,contact lines and bearing cables are classified by means of region growth and neighbor analysis.The constraints on the orbital environment are proposed.
