Abstract
Systems and methods for detecting contamination on a sensor cover. In an example, an image sensor of a vehicle may be used to capture an image of an environment of the vehicle. A sensor cover may be positioned outwardly from the image sensor and may form a covered volume around at least a sensing surface of the image sensor. A light source may be positioned in the covered volume. A management module may be coupled with the image sensor. The management module may be configured to receive test image data of the environment generated by the image sensor while the light source is on, compare the test image data to baseline image data generated while the light source is off, and detect whether contamination exists on a surface of the sensor cover based on the comparison.
