Problems solved by technology

[0005] 1. The hardware requirements of the image acquisition device are high (requires adjustable focal length, adjustable light intensity, adjustable wavelength range of light allowed to pass, etc.), which will inevitably make the structure of the image acquisition device complex and the performance of each component high.
costs will increase
[0006] 2. Complex image acquisition devices must require complex control programs, many algorithms, and high requirements for the operation rate of the control unit.
The acquisition efficiency of the image acquisition device is low, and the cost will be in

Abstract

The invention discloses a multi-modal biological recognition device and an image transmission method thereof, and belongs to the field of biological recognition. The multi-modal biological recognition device comprises a control unit, a memory, a plurality of image acquisition devices and a data selector, wherein the data side of the control unit is connected with the data sides of the image acquisition devices through the data selector; the gate control side of the control unit is connected with the gate control side of the data selector; and a buffer space used for storing image data acquired by the image acquisition devices is opened up in the memory. Compared with the prior art, the multi-modal biological recognition device can connect the plurality of image acquisition devices on one camera interface of the control unit to acquire multiple paths of images, so that the resources of the control unit are saved, power consumption is lowered.

Description

technical field [0001] The invention relates to the field of biometric identification, in particular to a multimodal biometric identification device and an image transmission method thereof. Background technique [0002] Biometric technology mainly refers to a technology for identity authentication through human biometrics. Human biometrics are usually unique, can be measured or automatically identified and verified, and are hereditary or lifelong. Therefore, biometric authentication technology Compared with traditional authentication technology, there are great advantages. The biological characteristics used for biometric identification include hand shape, fingerprint, face, iris, retina, pulse, auricle, etc. People have developed a variety of biometric technologies such as hand shape recognition, fingerprint recognition, face recognition, and iris recognition. [0003] Biometric technology has been widely used in various fields, and a variety of biometric devices have eme...
