Access control equipment based on digital cloud intercom system and control method of access control equipment

Abstract

The invention relates to access control equipment based on a digital cloud intercom system. The access control equipment comprises an entrance machine body, wherein the entrance machine body comprisesan image acquisition module and a controller; the controller comprises a reference image acquisition module, a feature point acquisition module and a storage module; the image acquisition module comprises a camera and a reflector; the entrance machine body is provided with a transposition assembly used for driving the camera and the reflector to move relatively; the transposition assembly can enable the camera and the reflector to move relatively, so that the camera can obtain more than two groups of video images with different angles at regular intervals; the feature point acquisition modulecan acquire a plurality of feature pixel point groups in each group of video images; and the control module can judge whether light living body detection is passed or not through comparing the feature collection point groups. Through a mode that the camera is movably matched with living body detection, the threat that a visitor unlocks the electronic lock through a plane picture is reduced. The method has the effect of improving the safety.

Description

technical field [0001] The invention relates to the technical field of building access control systems, in particular to an access control device based on a digital cloud intercom system and a control method thereof. Background technique [0002] At present, many residential buildings will install access control systems to limit the authority of people to go out to ensure the safety of residents. Face recognition to unlock. In the door-to-door access control system of a building, there are usually an outdoor station installed at the door and an indoor unit installed in the resident's room.

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: when the access control system stores the visitor's facial feature information, if other people have the visitor's photo during the time when the access control system reserves the access authority for the visitor, it is easy to pass the photo. The information deceives the face recognition system to enter the building, and the security is not high enough
