Embodiment Construction

[0030] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0031] figure 1 It is the outline drawing of the acquisition device of the present invention. There is a flat-bottomed groove in the middle of the upper surface of the acquisition device, and a slope at the top of the groove, which is used for finger positioning and image acquisition. There are electrodes and temperature sensors at the front and rear ends of the groove, which can be used as trigger switches and for liveness detection.

[0032] Fig. 2 is a structural diagram of the collection device of the present invention. Including: 1 infrared light source, 2 electrodes, 3 temperature sensor, 4 power supply, 5 control circuit, 6 infrared receiver, 7 vein image collector, 8 red light source, 9 fingerprint image collector.

[0033] When the system is working, put the finger in the groove, the top of the finger is close to the slope, the first knuckle is placed ...

Abstract

The invention provides a dual-mode biological image collecting device based on fingerprints and finger vein. The dual-mode biological image collecting device comprises a casing, a flat-bottomed groove is formed in the middle on the upper surface of the casing, an inclined plane is formed at the top part of the groove, electrodes are mounted at the front end and the rear end of the groove, vein image collecting infrared light sources are mounted on two side walls of the groove, a fingerprint image collecting red light source and a fingerprint image collector are mounted in the position of the bottom part of the casing corresponding to the inclined plane part of the top part of the groove, an infrared receiver and a vein image collector are mounted in the position of the bottom part of the casing corresponding to the groove, and a power supply and a control circuit for supplying power or signal transmission to the electrodes, a temperature sensor, the red light source, the infrared light source, the infrared receiver and the image collector are arranged in the casing. The performance of the biological characteristic recognition system for collecting image information in the invention is better than that of the single-mode biological characteristic recognition system just based on fingerprints and finger vein. Therefore, by adopting the dual-light-path system for collecting the images of both the fingerprints and the hand vein, the collecting speed is increased.

Description

(1) Technical field [0001] The invention relates to an image acquisition device in the field of biometric identification technology, in particular to a disposable image acquisition device for fingerprints and finger veins. (2) Background technology [0002] With the advent of the information age, more and more attention has been paid to the identification technology of human body based on biometric features. [0003] Fingerprint identification is to identify the operator or the operator based on information such as the lines and details of the human fingerprint. It has the advantages of easy extraction and high recognition accuracy, but it must be contact extraction, and there is a possibility of fingerprint damage and forgery; vein recognition is to identify the characteristics of blood vessels inside the human body, which is difficult to forge or surgically change. It is non-contact information collection. But the recognition accuracy needs to be further improved. Theref...
