A method and an arrangement for evaluating sensor images of an image-evaluating surroundings-detection system on a moved carrier, preferably a vehicle (1), are proposed, wherein areas in the sensor images captured by a camera (4) which are dark in relation to the surroundings are evaluated in chronologically successive evaluation steps in order to determine whether said dark areas are moving toward the carrier at the speed of said carrier, and in that these dark areas are detected as shadows (7) of a static object and corresponding signaling is performed.
