Embodiment approach

[0042] In one embodiment, the method also includes:

[0043] S5 marks the recognized human target, wherein the human target recognized in the video image is marked with a rectangular mark.

[0044] The above-mentioned embodiment of the present invention proposes a technical solution for detecting escalator passengers in the video surveillance images collected in the escalator scene, which can accurately detect human objects in the video images, and improves the efficiency of escalator passenger detection in the video images. The stickiness helps to lay the foundation for further target tracking based on detected human targets and the accuracy improvement of abnormal behavior recognition.

[0045] In one embodiment, step S1 specifically includes: receiving the video stream data of the escalator captured by the camera, wherein the camera is installed above or obliquely above the escalator through a bracket or a support rod, and its vision covers the entire passenger area of ​​th...

Abstract

The invention provides a target detection method and system for an escalator. The method comprises the following steps: S1, acquiring a video image of an escalator; S2, extracting a motion area and a background area in the video image according to the acquired video image; S3, further dividing a foreground part and a background part in the extracted motion area; S4, according to the obtained foreground part, using an SVM classifier to identify a human body target in the foreground part. According to the method and the system for escalator passenger detection for a video monitoring image acquired in an escalator scene, a human body target in the video image can be accurately detected, and a foundation is laid for further target tracking and abnormal behavior recognition accuracy improvement based on the detected human body target subsequently.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to an elevator-oriented object detection method and system. Background technique [0002] With the growth of the economy, the use of escalators has become more and more frequent, and there have been more and more safety accidents on the escalators. Most of the safety accidents on the escalator are due to the fact that when the state or behavior of the passengers on the escalator is abnormal, the escalator cannot respond and respond in time, but mechanically maintains the same working mode, resulting in the magnification and deterioration. It is impossible to arrange emergency workers to monitor the status of elevators and passengers next to each elevator. Therefore, it is very important to allow the escalator to automatically adjust the working mode when an abnormal situation occurs. Use video surveillance images to analyze and process the behavior of passengers on the e...
