Abstract
Dirt on a viewing window of a lidar is detected using a laser beam transmitted into a detection region and detecting light that is present in the detection region. An intensity image is generated as a greyscale image of intensities of laser reflections from the light reflected and detected as a result of the transmission of the laser beam. A background light image is generated as a greyscale image of background light from the light detected without transmitting a laser beam. The intensity image and the background light image are analyzed with respect to common features. When a number of common features falls below a predetermined number, it is concluded that there is dirt on the viewing window.
