Miniaturized vein recognition module and B column plaque integrated with same

The miniaturized vein recognition module comprises a camera module, a controller module and a microswitch module, the controller module comprises a PCBA, an MCU component, an SOC component and an RGB lamp are arranged on the PCBA in an integrated mode, the MCU component is connected with the microswitch module, and the MCU component is connected with the microswitch module. The microswitch module wakes up the vein recognition module to be powered on through manual contact and pressing, the camera module recognizes and collects palm vein feature information and transmits the palm vein feature information to the controller module, vein extraction, enhancement and feature comparison are completed through an SOC component in the controller module, and a vein recognition result is transmitted to a vehicle machine through an MCU component. And the vehicle machine central control feeds back to unlock and lock the vehicle door. The structure of an original module shell is omitted, so that the size of the internal spa
