The invention relates to a sensor system for recording a hand vein pattern. The sensor system comprises a first light source, which is designed to emit, during operation, electromagnetic waves in the near infrared range, which are able to be reflected by veins in a hand, over the entire surface, a camera having a camera chip for recording reflection signals for electromagnetic waves and for delivering image data that correspond to the reflection signals, a topography sensor for sensing three-dimensional topographies and a first processor unit, which is connected to the camera chip and to the topography sensor. The first processor unit is designed to generate from the image data from the camera and the three-dimensional topography data from the topography sensor, during operation, a normalized vein pattern for a hand or a feature vector that corresponds to the vein pattern. |
