Problems solved by technology

[0003] Existing patents for line crossing detection on railway platforms include platform laser line crossing detection device ZL201420511063.9, which uses laser transmitters and receivers, which requires high hardware costs and difficult installation. If a passenger crosses the line, the laser The detection line is immediately interrupted, and passengers who cross the line cannot be detected, and the number of people crossing the line cannot be counted

Embodiment

[0038] The camera captures a frame of the current platform image. This image information includes the warning area of ​​the platform, the dangerous area outside the warning line, and the safe waiting area inside the warning line.

[0039] The railway pick-up management personnel will set the corresponding area according to the situation of the platform. Set up dangerous areas, safe yellow line warning areas, and safe waiting monitoring areas.

[0040] The camera collects the current picture in real time, and extracts the moving target based on the background difference method of the Kalman filter algorithm.

[0041] For image acquisition correction, due to the pitch and rotation of the camera, there is a reprojection relationship between the imaging surface of the camera and the imaging surface of the ideal camera, so the reprojection transformation is used to transform the actual imaging surface into the ideal imaging surface of the camera.

Abstract

The invention provides a railway platform crossing detection method, which collects the current picture in real time, uses the background difference method based on the Kalman filter algorithm to extract the moving target on the collected current picture; marks the moving target close to the boundary, and marks the current position of the moving target. The position state, the mark inside the boundary area and the action of crossing the boundary line is ‑1; the mark is 1 outside the boundary area and the action of crossing the boundary line; the target mark of the previous frame is subtracted from the target mark of the next frame to select If the final mark value is 2, it is determined to enter, mark it, and give an alarm; if it is judged to be 2, it is to leave, and do not mark and warn it; judge whether the passenger has crossed the line by calculating the distance between the passenger's centroid and each area, if the passenger In the event of crossing the line and entering the dangerous area, an alarm will be issued immediately, which solves the problem that the railway inspectors can't take care of the rear and the front, and can't remind and care in real time. The method is low in cost and easy to install.

Description

technical field [0001] The invention relates to a method for detecting line crossing of a railway platform. Background technique [0002] With the continuous improvement of people's living standards and technological level, railways have become the transportation mode chosen by more and more passengers due to their advantages such as high safety factor, high speed and fast travel. Both the ordinary train platform and the EMU train platform follow the traditional open construction form. Although there are safety markings on the edge of the platform, some passengers are not aware of the danger and walk around randomly while waiting for the train to arrive; The rear can't take into account the front, so it can't achieve the effect of real-time reminder and care; sometimes some passengers with children, due to answering and calling on the platform or poor care, the children fall off the platform while playing, and even force the train to stop. Cause delay, serious will appear ...
