With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Example 1

As shown in fig. 1, the utility model discloses a specific embodiment of face identification attendance machine (this equipment for short hereafter) with prevent cheating function, including upper cover 100, lower cover 400 and set up display screen 200 and the functional unit 300 between upper cover 100, lower cover 400, wherein functional unit 300 specifically includes: a temperature measurement module 301, a distance measurement module 302, a camera module 303 (or called a face image recognition module), a light supplement module 304, a radio frequency recognition module 305, a control panel 306, an interface board 307, a speaker 308, and the like.

The control panel 306 runs with an attendance system, can record attendance data, can perform online or offline face recognition at the same time, and recognizes a face image acquired by the camera module 303, wherein online represents that the equipment is networked, and the face recognition can be performed through big data arranged on a cloud server so as to improve the recognition accuracy; the offline shows that the equipment is offline, and the human face recognition is carried out through the processor and the memory resource which are carried by the control panel board of the device, so that the efficiency is high. The work and flow of the attendance machine are not specifically described herein.

In this embodiment, the camera module 303 is mainly configured to collect image information for face recognition, and send the face image information to the control board 306 for online or offline face recognition to obtain attendance information of an attended person or perform anti-cheating verification on attendance.

In this embodiment, the RFID module 305 may support reading of an attendance card or an entrance guard card in one or more forms, such as RFID (radio frequency identification), NFC (near field communication), and may also support reading of NFC tag information of a mobile terminal, such as a smartphone, having an NFC function. The rfid module 305 is a conventional configuration of an attendance machine, and the form, structure and read/write method of the rfid module 305 are not specifically described herein.

In this embodiment, the distance measuring module 302 is configured to measure the distance between the apparatus and the face to be detected, and is disposed adjacent to the camera module 303 on the same side (i.e., on the same side of the attendance machine), so that when face recognition is performed, the real distance between the face to be detected and the attendance machine is measured at the same time, and whether the size of the acquired face is normal or not can be verified, thereby preventing cheating by means of photos, mobile phone videos, pictures, moving pictures, and the like when face recognition is performed by an attendance person. The general cheating means of face recognition includes: the photo and the mobile phone picture are adopted to provide static face information, and the mobile phone video and the motion picture are adopted to provide dynamic face information. However, the size of the normal photo and the size of the mobile phone video are far smaller than the size of the normal face, and in order to acquire the face image with the normal size, the photo and the mobile phone need to be close to or have an abnormal distance with the lens of the camera module 303, so that cheating can be prevented by ranging in face recognition.

Preferably, the distance measuring module is the distance measuring module 11 when flying, and the distance measuring module 11 size is little when flying, and has fine range finding precision, is applicable to short distance measurement.

In this embodiment, the light supplement module 304 may provide good illumination when performing face recognition by using a visible light image, so as to improve accuracy of the face recognition.

In this embodiment, the temperature measurement module 301 may collect temperature information of a face area of a person being checked through face recognition, and preferably, collect temperature information of a forehead area of a human face. In a specific embodiment, the temperature measurement module 301 generally employs a far infrared temperature measurement sensor, and has the characteristics of low cost, simple structure, convenient use, and the like. The body temperature detection can play an active role in epidemic situation prevention and control at the present stage. Meanwhile, the health condition of the staff can be effectively monitored and paid attention to, and the heating staff can be guided to seek medical advice in time.

In the face recognition process, the face recognition failure and other problems possibly caused by the unsatisfactory standing position of the checked-in person need to be adjusted by the action of the checked-in person, the standing position of the checked-in person and/or the position of the face are/is adjusted, and checking-in is performed again. In this embodiment, a voice prompt may also be given through the speaker 308 to give a guidance prompt to the attendance process, so that the attendance personnel can confirm by themselves that effective attendance is implemented.

For the prompt or warning, the device may also adopt other prompt or warning means, such as a buzzer, an LED indicator light, and the like, and for this purpose, the prompt device of the device may include one or more of a speaker, a buzzer, and an indicator light.

The utility model discloses an increase the range finding module, range finding in face identification process, whether the facial image who judges the collection through range finding is from real people's face collection to realize anti-cheating and detect.
