Embodiment 1

[0020] The present invention also includes an LED light strip 7, which is connected to the third-party interface module 2 for supplementary light, so as to ensure that the two-dimensional camera 3 can capture a clear face image.

Embodiment 2

[0022] On the basis of Embodiment 1, an indicator light 8 is also included. The indicator light 8 is connected to the third-party interface module 2 to indicate whether the system operation status is normal or not; whether the face recognition result is successful.

Embodiment 3

[0024] On the basis of embodiment 1 or 2, an ID card reader 9 is also included, and the ID card reader 9 is directly connected to the host computer 6, and the information in the ID card read is transmitted to the host computer 6, so that the registration personnel When the information is matched with the obtained 3D face model and 2D color face image; or when it is used to control the entry and exit of personnel, it is convenient to call out the corresponding face database for comparison and recognition.

[0025] The three-dimensional face recognition process in the entrance and exit control system based on three-dimensional face recognition of the present invention can be abstracted into five steps:

[0026] (1) Data acquisition. The 3D image of the face is converted into a series of data by the 3D face scanner 1 and sent to the calculation unit 5. According to these data, the original shape of the face can be accurately restored.

[0027] (2) Data processing, denoising t...

Abstract

The invention provides an access control system based on three-dimensional face identification. High-quality face data is obtained by a three-dimensional scanner. A two-dimensional camera is used for capturing a two-dimensional face image. The obtained three-dimensional face data and the two-dimensional face image are transferred through a third-party interface module to a computing unit to rebuild a three-dimensional face model. The three-dimensional face model is compared with registered models in a three-dimensional face model bank and recognized. The results are output to a host computer to run a software program. Behavior information of a visiting person is recorded and stored and access control is performed. At the same time, data communication with a liquid crystal display is performed and the needed information is displayed on the liquid crystal display. According to the access control system, three types of information, namely three-dimensional face model information, identification card information and two-dimensional face picture information, are matched, bound and stored in a backend database, thus facilitating recognition and looking up and largely enhancing the safety and stability of the access control system.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to an entrance and exit control system based on three-dimensional face recognition. technical background [0002] The access control system is an electronic system or network that uses custom character recognition or pattern recognition technology to identify the entrance and exit targets and controls the opening and closing of the entrance and exit actuators. The entrance and exit control system is mainly composed of reading part, transmission part, management / control part, execution part and corresponding system software. There are various construction modes of the access control system. According to its hardware composition mode, it can be divided into integrated type and split type; according to its management / control mode, it can be divided into independent control type, network control type and data carrier transmission control type. The various components of the integrated...
