利用DR区域马氏距离不变量在铁路编组场进行在场检测

Presence detection using DR region mahalanobis invariable in marshalling station

铁路交通中逐渐开始利用视频处理方法来提取交通信息。与公路相比,铁路中视频信号在目标尺寸、目标运行轨迹和视场规模等方面具有不同特点。根据这些不同特点,为了解决铁路编组场实际工作中检测车辆溜放位置的问题,提出了利用DR区域马氏距离不变量作为在场检测器的方法,并给出了具体计算结果。

It is important to obtain the traffic information using the video processing in rail transportation. To compare with the road transportation, the video signal of rail transportation has different characters in the object size, movement trajectories and visual range. Based on these characters, in order to serve a problem of position detection in marshalling station, this paper proposes the new Algorithm of Presence Detection to obtain the position information of train using DR parameter based in the mahalanobis invariable. In the end, a computation example in marshalling station is given.
