Access control device based on face recognition

Abstract

The invention belongs to the technical field of access control devices and relates to an access control device based on face recognition. The access control device comprises an access control bottom box and an access control top cover; the access control top cover is detachably mounted on the access control bottom box; a central processing unit and a buzzer are fixedly mounted in the access control bottom box; a through hole is formed in the upper side of the access control top cover; a face recognition mechanism is arranged in the access control bottom box and comprises a face recognition box fixedly installed in the access control bottom box, a camera fixedly installed in the face recognition box and a recognition unit; one end of the face recognition box is matched with the through hole in the access control top cover; and the camera is electrically connected with the recognition unit. Image errors occur in the face recognition process of the camera due to the refraction phenomenon of rainwater, as a result, the comparison calculation amount of the recognition unit is increased,the whole face recognition time is prolonged. With the access control device based on face recognition of the invention adopted, the above problem can be solved, and the face recognition sensitivity of the whole device in rainy days is improved.

Description

technical field [0001] The present invention relates to the technical field of access control devices, more specifically, an access control device based on face recognition. Background technique [0002] The face recognition access control device is based on face recognition technology to control the entrance and exit, which is safe and convenient, and has a high visualization program. Automatically verify and identify the identity of people entering and leaving through face recognition, complete the access control of personnel, restrict the entry of irrelevant personnel, combine face recognition hardware equipment with attendance management software, seamlessly connect with existing access control systems, and realize access control and attendance 2 in 1 for easy management. [0003] The existing access control devices are mostly exposed to the air, and do not have a good rain-shielding structure.

Problems solved by technology

[0003] The existing access control devices are mostly exposed to the air, and do not have a good rain-shielding structure. When the rainy weather is accompanied by wind, it will cause the camera mirror to be blurred with rainwater, and then when performing face recognition, the access control device The internal recognition time is prolonged and the recognition sensitivity is reduced
