Trip detecting method and device based on video

The invention provides a trip detecting method and device based on video. The trip detecting method comprises the steps of obtaining moving objects in a monitoring scene; tracking the moving objects in the monitoring scene; setting gravity center falling thresholds of the objects according to the monitoring scene; determining whether the objects trip in the monitoring scene or not by the utilization of the set threshold. By the utilization of the trip detecting method and the trip detecting device based on the video, trip accidents can be detected quickly and accurately, the trip accidents occurring in any direction and far from or close to a video camera can be detected, sitting and lying can be distinguished from tripping, no parameter needs adjusting, environment adaptivity is provided, and trip accidents in different domestic scenes can be detected.
