Problems solved by technology

[0004] However, the setting of the limit device not only increases the volume and weight of the biometric device, but also increases the production cost of the equipment, and the palm needs to touch the limit device, which cannot guarantee hygiene and safety.

Embodiment 5

[0125] An embodiment of the present application also provides a non-contact biometric device, including a memory, a processor, and a computer program stored in the memory and operable on the processor, wherein the memory is used to store software programs and modules, The processor executes various functional applications and data processing by running software programs and modules stored in the memory. Specifically, the processor implements the following steps by running the above-mentioned computer program stored in the memory:

[0126] In standby mode, collecting a first infrared image at a first frequency;

[0127] If there is a biological feature in the above-mentioned first infrared image, enter the working mode, and collect the visible light image and / or the second infrared image at the second frequency;

[0128] performing biometric identification based on the collected visible light image and / or the second infrared image;

[0129] Wherein, the above-mentioned second...

Abstract

The invention provides a non-contact biological recognition method and device, and belongs to the field of biological recognition, and the method comprises the steps: collecting a first infrared imageat a first frequency in a standby mode; if the biological characteristics exist in the first infrared image, entering a working mode, and collecting a visible light image and / or a second infrared image at a second frequency; performing biological recognition based on the acquired visible light image and / or the second infrared image; wherein the second frequency is greater than the first frequency. According to the invention, organism detection is carried out on the collected first infrared image in a low-power-consumption state, whether to enter the working mode or not is determined, and theorganism only needs to make the to-be-detected part get close to the image collection area, so that the organism identification process can be triggered, and automatic detection and identification ofthe organism identity in a non-contact mode are realized.

Description

technical field [0001] The present application belongs to the field of biometric identification, and in particular relates to a non-contact biometric identification method and device. Background technique [0002] With the development of biometric identification, currently more mature biometric feature technologies include fingerprint recognition, face recognition, iris recognition, palmprint recognition, etc., but fingerprints or faces are easy to be forged and cracked, and their security is poor; Although iris recognition has high security, its equipment cost is also high, and it is still not widely accepted by the market; palmprint recognition and palm vein recognition are relatively new biometric technologies, and palmprint recognition has more advantages than traditional fingerprint recognition. More feature points can achieve higher security; palm vein recognition not only has many feature points, but also palm veins are hidden under the skin and cannot be easily stole...
