Close-range self-protection energy-saving environment-friendly face recognition door lock

Abstract

The invention relates to the technical field of face recognition, and provides a close-range self-protection energy-saving environment-friendly face recognition door lock which comprises a shell, a far-near sensor is fixedly connected to the inner wall of the shell, an electromagnet is fixedly connected to the outer wall of the far-near sensor, and an iron block is movably connected to the outer wall of the electromagnet. According to the close-range self-protection energy-saving environment-friendly face recognition door lock, the distance between a user and a face recognition equipment is closer, the magnetic force of an electromagnet is reduced along with the closer distance, the electromagnet attracts an iron block to stretch a reset spring, the iron block moves to drive a sliding block to move, and the sliding block enables a rod sleeve to move through a linkage rod on the outer wall of the sliding block; a camera slowly gets away from a magnifying lens and adjusts the size of an input picture according to the distance between the person and the face recognition equipment, so that the face recognition equipment can input and judge conveniently, subsequent operation is carried out subsequently, and the situation that the distance between the person and the face recognition equipment is close, and the face recognition equipment cannot input the face completely is prevented.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an energy-saving and environment-friendly face recognition door lock for short-distance self-protection. Background technique [0002] Face recognition is a biometric identification technology based on human facial feature information. It uses a camera to collect images and video streams containing human faces, and automatically detects and tracks human faces in the images, and then detects the detected people. A series of related technologies for face recognition, usually used in door locks, are non-contact and non-coercive. [0003] In the existing technology, face recognition needs to pay attention to the distance between the face and the recognition device. The small distance between the two will cause the recognition device to fail to record all faces into the device, and cannot follow the distance between the person and the device. Automatically adjust the size of...

Problems solved by technology

[0003] In the existing technology, face recognition needs to pay attention to the distance between the face and the recognition device. The small distance between the two will cause the recognition device to be unable to record all faces into the device, and cannot follow the distance between the person and the device. Automatically adjust the size of the input screen, and the recognition device will be blocked by foreign objects, so self-protection cannot be achieved. Therefore, an energy-saving and environmentally friendly face recognition door lock with close-range self-protection came into being.
