According to the problem that different thickness of the individual fingers and different veins size for finger vein identification system and the problem that it is hard to obtain small vein image accurately,an intelligent finger vein image acquisition device is developed which can automatically adjust parameters and then obtain accurate imagine.The collection device is discussed in detail including structure,working principle and intelligent parameters adjustment algorithm based on fuzzy control and multi-sensor fusion.Practical application shows that the device can be more accurate to obtain veins images of different individuals,which greatly improved the original finger vein image quality.
