Problems solved by technology

It can be seen from this method that the fingerprint detection element is used when identifying fingerprints. Due to the contact judgment, the fingerprint sensor may not be sensitive enough due to long-term use, or the fingerprint cannot be recognized due to damage. In addition, there are hygiene problems.

Embodiment

[0017] Such as image 3 As shown, the face recognition device applied to guards includes an infrared camera 1 , a control circuit part 2 , a power cord 3 , and a housing 4 .

[0018] The control circuit part 2 includes a face recognizer, a memory, a door lock control module, and a microprocessor unit; the camera is connected with the face recognizer, the memory is connected with the face recognizer, the microprocessor is connected with the door lock control module, and the face The recognizer is connected to the microprocessor; the face recognizer receives the face information obtained by the camera, recognizes it, and compares it with the data stored in the memory, and outputs the result to the microprocessor unit, which is judged by the microprocessor unit. If the comparison is successful, the microprocessor controls the door lock control module to open the door lock.

[0019] Such as figure 2 As shown, the main work of the face recognizer includes image compression, imag...

Abstract

The invention belongs to the technical field of image recognition and information processing, and discloses a face recognition device applied to an entrance guard. The face recognition device applied to the entrance guard mainly comprises a camera, a face recognizer, a memorizer, a door lock control module and a microprocessor unit, wherein the camera is connected with the face recognizer, the memorizer is connected with the face recognizer, the microprocessor unit is connected with the door lock control module, and the face recognizer is connected with the microprocessor unit. The face recognizer is used for receiving and recognizing the face information obtained by the camera and comparing the face information with data memorized in the memorizer, the compared result can be output to the microprocessor unit and can be judged by the microprocessor unit, and a door lock is unlocked by the door lock control module which is controlled by the microprocessor unit if the comparison is succeeded. By adopting the face recognition mode based on a video, the security of an entrance guard system is increased, and the misjudgment as an identity card is stolen by others can be avoided; and by adopting the non-contact type face recognition mode, the sanitation problem due to the adoption of contact-type fingerprint recognition can be avoided.

Description

technical field [0001] The invention belongs to the technical field of image recognition and information processing, and in particular relates to a face recognition device applied to guards. Background technique [0002] Face recognition refers to the use of image processing and pattern recognition technology to identify or verify one or more faces from static or dynamic scenes based on the known face sample library. Usually, the basic information can be obtained after the recognition process, including the position, scale and posture information of the face. Using feature extraction technology can further extract more biological features. [0003] Face recognition technology has extensive and special uses in the field of national important organs and social security. Compared with other human biometric recognition technologies, face recognition technology has the best concealment. It is the most important technological means and technology for international anti-terrorism ...
