Abstract

The invention discloses an access control system control method and an access control system. The method comprises the following steps: acquiring position information of a target object in real time by using a positioning device; adjusting the focal length of a target object shot by a camera device according to the position information so as to shoot the target object; according to the image information shot by the camera device, judging whether the target object belongs to a specified person with permission of passing through the access control system or not; and when the target object belongs to a designated person with permission of passing through the access control system, collecting position information of the target object by utilizing a positioning device according to a preset period, analyzing the distance between the target object and a door lock according to the position information, and controlling the door lock to be opened when the distance is smaller than a preset threshold value. According to the access control system control method, the focal length of the target object shot by the camera device is determined according to the position information of the target object, the identity recognition efficiency and success rate of the target object are improved, and therefore the recognition rate of the face target object is increased.

Description

technical field [0001] The invention belongs to the technical field of access control, and in particular relates to an access control system control method and an access control system. Background technique [0002] At present, most of the access control systems have a face recognition system. When the user approaches the access control, the camera device on the access control starts and collects the user's face information. When the face information recognition passes, the door lock is opened. When the camera device collects the user's face information, it is necessary to locate the user to obtain the face information. The existing positioning methods mostly use methods based on signal strength, such as GPS signal strength, etc., which are easily blocked by objects and cause signal strength. changes, resulting in inaccurate positioning. [0003] Due to the inaccurate positioning of the user, when the camera device captures picture information for face recognition, the corr...
