Abstract: Method for determining cleaning information for a camera sensor which includes a blockage on a transparent camera sensor component in an optical camera sensor path, the method including: processing a captured camera image with a neural network algorithm which determines as an output a degree of camera sensor blockage by segmenting a part of the camera image and a camera sensor blockage class by classification of a part of the camera image, determining cleaning information dependent on the camera sensor blockage degree and the camera sensor blockage class, wherein the cleaning information describes that a cleaning of the camera sensor is required if a cleaning criterion is assigned to the determined camera sensor blockage class and if a degree threshold is exceeded by the determined camera sensor blockage degree, and transmitting the cleaning information to a camera sensor cleaning device to clean the camera sensor.
