The invention discloses a vein-fingerprint-face composite recognition system with an automatic light brightness control function. The system includes a support frame which is provided with a verticaladjusting slot. A sliding block is arranged on the vertical adjusting slot. The sliding block can move along the vertical adjusting slot or be fixed to the vertical adjusting slot. A mounting rod is arranged on the sliding block. The mounting rod is provided with a horizontal adjusting slot. A fixing device is arranged on the horizontal adjusting slot. The fixing device can move along the horizontal adjusting slot or be fixed to the horizontal adjusting slot. The support frame is further provided with lighting equipment which is connected with a controller. The controller is used for controlling the angle and light intensity of the lighting equipment. The system is more convenient to install and more flexible in installation position. The angle and light intensity of the lighting equipmentare adjusted according to the illumination conditions of the external environment so that the vein-fingerprint-face composite recognition system has a better recognition effect.
