摘要:
The invention relates to a method for detecting and assessing reflections on a road (7). A camera (2) is provided and is used to produce at least two digital images of at least one point (3) of the road, wherein the images are produced 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 at least one point (3) of the road in the at least two digital images using digital image processing algorithms. Road reflections are particularly preferably assessed using an approximative approach. An item of road condition information is determined on the basis of the detected reflection, in particular an item of road condition information which states whether the road (7) is dry, wet, snow-covered or icy. The invention also relates to an apparatus (1) for carrying out the above-mentioned method and to a vehicle having such an apparatus (1).
