A method for monitoring a sensor system. Sensor data of the sensor system are read in and information of the sensor data from different elevations of the sensor data is projected as image data into an azimuthal image plane. The information from at least two image areas of the image plane is evaluated in a spatially resolved manner in order to recognize a local sensor blindness of the sensor system. A blindness notification for an image area is output if the sensor blindness is recognized in the image area.
