Text/Era Times refers to vein identification experts
Time flies are really fast, and it is said that the time is different from the previous time. I do not know whether or not everyone has this feeling. That is, when we were small, we thought that one day could be done for a long time. However, now, one day, Can not do much, just one day, I feel very fast. At present, the Compilation of the Finger vein recognition technology basic knowledge manual has been completed more than half of the time according to the plan. During this period, many friends and customers have found the experts of the era vein finger vein recognition to give encouragement and support. I am very grateful to these friends and Customers, we do long-term business, if there is any advice, we can always come forward with us, but also for the better development of the industry.
Today's Easy Times means that vein recognition experts share with you why there is a camera module for the finger vein recognition module. As for needs, in fact, this still needs to understand the composition of the finger vein recognition module. If you do not understand it, you can also refer to the next fingerprint identification. Although fingerprint recognition recognizes the texture of the outer cortex, it also requires a camera module.
The principle of finger vein recognition is to use the veins inside the finger to attract specific wavelengths of light. After using near-infrared camera illumination, an image of the finger vein can be obtained. After a specific algorithm, characteristic values ​​can be formed and the ratio can be compared. For identity analysis and identity verification, it is such a recognition principle. Among them, the camera module will be involved. If there is no camera module, it cannot be illuminated and it cannot be imaged. Therefore, the finger vein recognition module must be It is necessary to have a camera module.
Some people may worry that this camera module and near-infrared light irradiation, whether the emission of light will damage the human body, in fact, there is no need to worry about, because there is such light in the sun, the sun we all say that we must always be a sun Health, not to mention we are only momentary exposure, will not affect the skin of the finger and the veins of the internal blood vessels. It is much better than what the flash camera does, and the fingers are not as easily affected by the external environment and light as the iris. Does not change the veins inside the finger.
The general finger vein recognition module has a camera module and other components, such as a core processing circuit board, a near-infrared light source, a camera module, a filter, etc. These core components are formed. The finger vein recognition module, from the point of view of these several core components, we know that, in fact, the camera module is still very important Kazakhstan, is an integral part of the vein recognition module, that is, can not be without Kazakhstan.
