Description

Infrared face recognition system

The present invention relates to a face recognition system, which is mainly integrated with a gradient image display technology by using a visible light lens and an infrared lens, so that it can be effectively recognized during daytime and nighttime.

The traditional access control is mainly based on the holding of keys, wafer cards, etc., or by means of passwords and other means of access control. However, both methods may be forgotten, lost, and forgotten. It is inconvenient, and it is easy to copy and decode. This has caused loopholes in community/company management. With the 9/11 attacks, homeland security has become an important issue. Therefore, fingerprints, irises, handwriting, voiceprints, faces Biometric identification methods such as identification have been developed. Since biometric methods are based on unique features and do not need to be carried or invasive, this also achieves convenience and safety.

At present, the biometric identification method, due to the cooperation of various technologies, is the most common face recognition. It uses the photographic lens to capture the features of multiple angles of the face for identification. However, when it is applied to the access control, some The problem is that for ordinary employees/residents, the difference in image discrimination is often caused by changes in light patterns at day and night and the difference in portrait angles, which may lead to problems such as employee/household misidentification and rejection. In addition, for those who are not attentive, in the absence of an administrator, photos can be used under the lens, usually can avoid mechanical identification, therefore, there is an urgent need to improve these problems in identification management, providing a safer and more convenient identification method.

The main purpose of this creation is to provide an infrared face recognition system. The system includes an input unit, an image capture unit, an image construction unit, an identification processing unit, and a database. The input unit is used to generate an input signal. Image capture unit, including visible light The lens and infrared lens are used to capture visible and infrared images of the visitor's face. The image construction unit receives the visible light image and the infrared image and integrates it into a face image signal. The identification processing unit is connected to the input unit, the image capturing unit, the image construction unit, the data base, and the external door lock unit and the notification unit, and receives the input signal to generate an activation signal to activate the image capturing unit to receive the face. The image signal searches for the matching face data from the database. When the face data matches, an unlock signal is generated to open the door lock unit, and when the face data does not match, a notification signal is generated to start Notification unit.

This creative infrared face recognition system can be mainly used for community or company access control management. It is characterized by the integration of infrared lens and visible lens, and the integration of images on the image construction unit by infrared face gradient imaging technology, so that it can be used during daytime and nighttime. It can be effectively identified to avoid being affected by light differences. The overall face recognition rate can be effectively improved. In addition, it can avoid the problem of people avoiding the face recognition system with photos, and it is more convenient and more convenient. The effect of security.

The first figure is a schematic diagram of the infrared infra-red face recognition system.

The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.

Referring to the first figure, a schematic diagram of the present infrared face recognition system. As shown in the first figure, the present infrared infrared face recognition system 1 includes an input unit 10, an image capture unit 20, an image construction unit 30, an identification processing unit 40, and a database 50. The input unit 10 is configured to generate an input signal. The image capturing unit 20 includes at least one visible light lens 21 and at least one infrared lens 23 for capturing visible light images and infrared images of the face of an external visitor 100, respectively. The image constructing unit 30 is connected to the image capturing unit 20 for receiving the visible light image and the infrared image and integrating the same into a face image signal. The database 50 stores a plurality of personal face data. The identification processing unit 40 is connected to the input unit 10, the image capturing unit 20, the image construction unit 30, the database 50, and the external department lock unit 60 and the notification unit 70, and receives the input signal to generate a startup. The signal is used to activate the image capturing unit 20 to receive the facial image signal, and search for the matching facial data from the database. When the facial data matches, an unlocking signal is generated to activate the door locking unit 60. When the face data does not match, a notification signal is generated to activate the notification unit 70.

The infrared face recognition system of the present invention can be mainly used for access control of a community or a company, and the input unit 10 can be a doorbell, a keyboard input device, a voice input device, a radio frequency identification reader, a touch input device, etc., and can further be a fingerprint. The input device, the face data of the database 50 includes household/employee face data, and common visitor information, and the further database can also store the fingerprint data of the household/employee, the password data, the voiceprint data, the card number of the access card, and the like. The identification processing unit 40 searches for the face data in the database according to the input password data, voiceprint data, fingerprint data, card number of the access card, and the like. The notification unit 70 can be a buzzer, a voice notifier, or the like.

Further, the input unit 10 and the image capturing unit 20 can be further integrated on a touch device. The touch device can communicate with the identification processing unit 40 in a wired/wireless manner. Further, the input unit 10, the image capturing unit 20, the image constructing unit 30, the identification processing unit 40, and the database 50 of the entire infrared face recognition system 1 can be integrated into a touch device, and the door lock unit 60 And the notification unit is electrically connected 70. And further, the image construction unit 30 can also be connected to the database to create new face data.

The feature of this creation is that the infrared image is combined with the visible light lens to integrate the image on the image construction unit 30 by infrared face gradient imaging technology, which enables effective identification during daytime and nighttime, and is prevented from being affected by light differences. In addition, the recognition rate of the face is greatly improved, and in addition, the problem of the person hiding the face recognition system can be avoided, and the effect is more convenient and safer.
