Abstract

In a method for detecting and assessing reflections on a road (7), a camera (2) produces at least two digital images of at least one point (3) of the road, respectively from different recording perspectives (A, B) of the camera (2). Diffuse reflection and specular reflection of the road (7) are then detected by assessing differences in the appearances of the point (3) of the road in the at least two digital images using digital image processing algorithms. Road reflections are preferably assessed using an approximative approach. An item of road condition information is determined based on the detected reflection, preferably an item of road condition information which states whether the road is dry, wet, snow-covered or icy. Also provided are an apparatus (1) for carrying out the above-mentioned method, and a vehicle having such an apparatus.
