A multi-view finger vein image acquisition device comprises a camera module, a lighting module, a driving module and a supporting module, a rotating track is arranged on the supporting module, the driving module comprises a motor and a rotating handle, the motor is installed on the supporting module, the rotating handle is installed on the motor, and the camera module and the lighting module are oppositely arranged and connected with the rotating handle. The camera shooting module and the lighting module are further installed on the rotating track through pulleys, a space allowing the fingers to be placed in is formed between the camera shooting module and the lighting module, the motor drives the rotating handle to rotate, the rotating handle drives the camera shooting module and the lighting module to synchronously rotate along the rotating track, and the camera shooting module conducts multi-view camera shooting on the fingers; and the lighting module provides illumination of a corresponding visual angle for a finger during multi-visual-angle camera shooting. According to the multi-view finger vein image acquisition device, multi-view all-dimensional flexible acquisition of finger veins is realized only by using a single camera, so that the input cost is greatly reduced, the equipment structure and the control program are simplified, and high-quality and easy-to-operate multi-view finger vein acquisition is realized at low cost.
