[0007] As a preferred technical solution of the utility model, the iris face acquisition and recognition device includes an iris camera distance sensing device, a face recognition camera, an LED fill light and an infrared camera. The iris camera is fixedly installed on the iris face acquisition and recognition device. The face recognition camera is fixedly installed in the middle of the surface of the iris face acquisition and recognition device. The distance sensing device, the LED fill light and the infrared camera are all fixedly installed on the iris face acquisition and recognition device.

[0008] As a preferred technical solution of the present utility model, a borrowing and returning area is fixedly installed on one side of the front surface of the device body, and a management area is fixedly installed on one side surface of the device body.

[0009] As a preferred technical solution of the utility model, the LED fill light is arc-shaped, the LED fill light is located above and below the face recognition camera, and the distance sensing device is located on one side of the face recognition camera.

[0010] Compared with the prior art, the utility model provides a 24-hour self-service library device based on iris and face recognition, which has the following beneficial effects:

[0011] The utility model provides a 24-hour self-service library device based on iris and face recognition. Through the cooperation of iris face collection and recognition devices, multimedia display screens and second-generation ID card recognition devices arranged in the borrowing and returning area and the management area, the identity information of the operator as well as the face and iris can be collected, so that when readers need to borrow books, they only need to recognize the face and iris to borrow books. At the same time, when the ID card is not carried with them, the borrowing and returning of books can still be carried out on the 24-hour self-service library device. In addition, due to the iris face collection and recognition device and the second-generation ID card recognition device, the information can be collected more comprehensively when it is collected for the first time, thereby effectively improving the security performance of the 24-hour self-service library device.
