Video content risk detection method, device and system

Abstract

The invention discloses a video content risk detection method, device and system. The method comprises the steps that a first camera sends first video data to a monitoring device; a second camera sends the second video data to the monitoring device; and the monitoring device determines a user to be analyzed, extracts a first background feature when the user to be analyzed is located at a first preset position, extracts a second background feature when the user to be analyzed is located at a second preset position, and performs calculation to obtain a matching degree between the to-be-analyzedbackground feature and a preset background cooperation model, extracts a first moment corresponding to the occurrence of the user to be analyzed at the first preset position from the first time information, extracts a second moment corresponding to the occurrence of the user to be analyzed at the second preset position from the second time information, and calculates a time interval between the first moment and the second moment; and if the matching degree is lower than a preset background threshold or the time interval is greater than the preset time threshold, generates a first comparison result, and determines that a preset risk exists.

Description

technical field [0001] The present invention relates to the field of video monitoring, in particular to a video content risk detection method, device and system. Background technique [0002] Existing automatic teller machines (Automatic Teller Machine, referred to as ATM) are generally arranged in self-service banks, and after inserting a bank card on the ATM, bank counter services such as withdrawal, deposit, and transfer can be performed on the ATM. Due to the openness, convenience and environmental particularity of self-service banks and automatic teller machines. Criminal activity targeting self-service banks and ATMs has increased in recent years. [0003] However, the traditional ATM video surveillance system is mainly to record the video. After the event occurs, the recorded video is used to obtain evidence afterwards, so as to eliminate disputes and solve the case. However, such a mechanism can only provide evidence collection after the event, and cannot achieve R...
