Skating rink monitoring method and device based on behavior detection

Abstract

The invention discloses a skating rink monitoring method and device based on behavior detection. The method comprises the following steps of: subtracting two adjacent video frames of a real-time monitoring video of a skating rink to obtain a video difference image, and forming a video difference image sequence by a plurality of video difference images; performing human body key point detection andsubset division on the video difference image sequence based on a human body recognition model to obtain a human body target in the video difference image and a key point set of the human body target; based on a three-dimensional convolutional neural network, performing behavior identification on each human body target and key points thereof in the video difference image to obtain a behavior typeof the human body target;and triggering a prompt when the behavior type is judged as a dangerous behavior. According to the method, the behaviors of the skating person can be analyzed by processing the monitoring video, and the dangerous behaviors are prompted, so that the automatic monitoring of the skating field is realized, the manpower is saved, and the monitoring effect of management personnel is also improved.

Description

technical field [0001] The present application relates to the technical field of machine learning, in particular to a method and device for monitoring skating rinks based on behavior detection. Background technique [0002] In the skating rink, it is necessary to pay attention to the safety of the skaters. Dangerous behaviors are particularly prone to occur for beginners skating, such as falling, etc., and accidents are likely to occur. In the prior art, usually one or more place management personnel observe the behavior of all skaters on the skating rink at all times around the skating rink. However, this method depends too much on the working attitude and mental state of the managers and the situation of the skating rink. For example, when there are many skaters, the venue is too large or the managers are slack, it is very likely that the dangerous behavior of the skaters will not be discovered in time. , so that unexpected events occur.
