Claim:
1. A method of determining a state of a pavement on which a vehicle is driving, comprising merging locally measured data received from at least one locally measuring device that measures a local pavement state or coefficient of friction of the pavement, with camera data of a camera image received from a camera, and performing an image analysis comprising analyzing the camera data, which involves: sub-dividing the camera image into a two-dimensional grid of grid cells representing image sectors of the camera image in a plane of the pavement, assigning the locally measured data representing the local pavement state or coefficient of friction respectively to individual ones of the image sectors of the camera image in the camera data while taking odometric information of the vehicle and time information into account, and taking the locally measured data representing the local pavement state or coefficient of friction into account for support and/or plausibilization of an anticipatory and locally resolved coefficient-of-friction estimation or state-of-pavement determination based on the camera data.
