Train dynamic time stop method and device based on video analysis

Abstract

The embodiment of the invention provides a train dynamic time stop method and device based on video analysis. The method comprises the following steps of acquiring a video image of a train within a preset range in a station stop process by utilizing a camera mounted on each train door; detecting the movement amount of a target object in the video image, sending a detection result to a train operation control system, and controlling whether the train door is closed or not by the train operation control system according to the detection result so as to stop the train dynamic time. The device executes the method. According to the method and the device for stopping the train dynamic time based on video analysis, the movement amount of target objects in the video images near the train door is detected to determine whether the passenger completes the riding and descending activities or not so as to control whether the train door is closed or not, so that the train stopping time can be controlled, the train stopping time can be flexibly and effectively controlled in the train stopping process, and the urban rail transit operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for a dynamic time stop of a train based on video analysis. Background technique [0002] Based on the needs of rail transit system operation management, it is particularly important to control the train stop time. [0003] The control of train stop time is related to the operating efficiency of the rail transit system, and is also an important parameter for formulating train operation diagrams. In the prior art, the fixed stop time of the train at the station is determined in advance based on the historical data such as the number of people getting on the train, the number of people getting off the train, the number of doors, and the degree of congestion in the train, such as the fixed stop time of the train every time it arrives at a station. The time is two minutes. Usually, the length of the fixed stop time is longer, so as to ensure that passengers ...
