Image analysis system and device suitable for track detection

Abstract

The utility model relates to an image analysis system and device suitable for track detection, and the system comprises an image acquisition unit which is disposed on a track traffic vehicle to acquire an image of the track when the track traffic vehicle passes through the track; the processing unit is used for processing the collected images to judge the state of the track, and the processing unit comprises an image extraction module, an image positioning module, a geometric judgment module and a track analysis module. According to the image analysis system disclosed by the utility model, the track detection cost can be reduced, the track detection efficiency can be improved, the huge influence on the track detection by an image method due to the motions of turning, sinking and floating, nodding and the like of a train can be eliminated, and three-dimensional space coordinate positioning can be carried out on the detected track by utilizing a single-machine image. 本实用新型涉及一种适用于轨道检测的影像分析系统和装置，所述系统包括：影像采集单元，其设置于轨道交通车辆上，以对轨道交通车辆通过轨道时该轨道的影像进行采集；以及处理单元，其对所采集的影像进行处理，以判断所述轨道的状态，所述处理单元包括：图像提取模块、影像定位模块、几何判定模块以及轨道分析模块。根据本实用新型的影像分析系统，能够降低轨道检测成本，提高轨道检测效率，消除了由于列车转弯、沉浮以及点头等运动对图像法轨道检测产生的巨大影响，并且能够利用单机影像对检测轨道进行三维空间坐标定位。
