A method for determining an image degradation of an imaging sensor is proposed, with the steps:Provide an image (210, 300) of an environment generated by the imaging sensor;Determining a degradation for each sub-image of a plurality of sub-images (301-312) of the image (210, 300) by means of a trained neural network (200); andDetermine the image degradation of the sensor, which has a ratio of a number of partial images of the image with certain degradation (309-312) to the plurality of partial images (301-312).
