Embodiment Construction

[0027] The spirit of the present invention will be described in detail below with the accompanying drawings. After understanding the preferred embodiments of the present invention, any person skilled in the art can change and modify the technology taught by the present invention without departing from the present invention. spirit and scope.

[0028] Please refer to figure 1 , which shows a functional block diagram of a human face determination system according to an embodiment of the present invention. The face recognition system uses visible light photos, infrared light photos and the sensed current target temperature to identify living faces.

[0029] The face detection system 100 includes a visible light camera 110 , an infrared light camera 120 , a non-contact temperature sensing device 130 and a processing element 140 . The non-contact temperature sensing device 130 may be an IR thermometer or other types of non-contact temperature sensing devices. The processing elem...

Abstract

The present invention discloses a system and method for identifying a human face. The system includes a visible light camera, an infrared (IR) camera, a non-contact temperature sensing device and a processing unit. The visible light camera and the IR camera aim at a same photograph zone for respectively photographing at least one visible-light picture and at least one IR picture. The non-contact temperature sensing device senses a present target temperature in a temperature sensing zone, which is in the photograph zone. When the processing unit detects that a human face is existed in the corresponding zone of the visible-light picture and that of the IR picture, it determines if the present target temperature is in a body-temperature range. When the present target temperature is in the body-temperature range, the processing unit determines that the human face detected in the corresponding zone is a live human face.

Description

technical field [0001] The present invention relates to a face judgment system and method. Background technique [0002] Since the face is an important biological feature of human beings, many face-related studies have been developed. Among them, an important application is face recognition, which uses computer analysis and comparison of visual features of faces to perform identity identification. When using face recognition as the basis for access control, it can save the management and construction costs of proximity cards, and also avoid the trouble of people entering and leaving the door forgetting to bring the card. Compared with other biometric identification methods, face recognition is carried out in a non-invasive and non-contact way, which is easily accepted by most people. In particular, when you have no time to swipe a card or press a password with both hands, you can feel the benefits of face recognition technology. [0003] In addition, another important fac...
