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.
