Three-Dimensional Finger Vein Recognition: A Novel Mirror-Based Imaging Device

Abstract: Finger vein recognition has evolved into a major biometric trait in recent years. Despite various improvements in recognition accuracy and usability, finger vein recognition is still far from being perfect as it suffers from low-contrast images and other imaging artefacts. Three-dimensional or multi-perspective finger vein recognition technology provides a way to tackle some of the current problems, especially finger misplacement and rotations. In this work we present a novel multi-perspective finger vein capt… Show more

“…According to our model, the vascular pattern is a projection of the blood vessels on the surface of the finger, independent of the angle of the light source or the camera. This means that 3D reconstruction by means of stereovision [22,23] will only lead to a reconstruction of the projection of the vessels on the 3D surface of the finger and will provide no information on the depth of the vessels.…”

“…They presented clear enhancement towards the tolerance against finger rolls and presented state-of-the-art identification accuracy. Kauba et al [76] introduced another 3D or multi-perspective capturing device that utilized mirrors to build a 3D finger vein recognition system instead of multiple cameras. This novel device employed a single camera, a single illumination module, and several mirrors to capture the finger from various rotational angles.…”

“…However, this is a rather complicated process requiring considerable computing resources, a more complex mechanical part of the system (e.g., using moving parts), requiring usually more space and, in many cases, more than one camera. This increases the cost of the device making it less attractive commercially and also, through considerable expansion, less reliable when compared to fixed systems equipped with a single camera [ 21 , 22 , 23 ].…”
