Method for detecting imaging degradation of an imaging sensor

A method for detecting imaging degradation of an imaging sensor includes (i) providing an image of a surrounding area, said image being generated by the imaging sensor; (ii) detecting imaging degradation for each sub-image of a plurality of sub-images of the image using a neural network trained for this purpose; and (iii) detecting the imaging degradation of the sensor, said imaging degradation exhibiting the ratio of the number of sub-images of the image with detected degradation to the plurality of sub-images.
