RISK DETECTION METHOD, APPARATUS AND SYSTEM BASED ON BACKGROUND COLLABORATION

摘要

The present invention provides a risk detection method, apparatus and system based on the background collaboration. The method comprises: a first camera sends first video data to a monitoring apparatus; a second camera sends second video data to the monitoring apparatus, the first camera and the second camera being provided at different positions in the environment to be detected; the monitoring apparatus recognizes the face corresponding to a user to be analyzed in the first video data and the second video data to determine said user, obtains video data comprising said user at the required point in the first video data and the second video data, extracts the background feature from the video data comprising said user at the required point, inputs the background feature obtained by extracting into a preset background collaboration model, and calculates to obtain the matching degree between the background feature and the preset background collaboration model; the monitoring apparatus compares the matching degree with a preset background threshold, if the matching degree is less than the preset background threshold, determines that the preset risk exists.
