DETECTION, IDENTIFICATION, AND MITIGATION OF LENS CONTAMINATION FOR VEHICLE MOUNTED CAMERA SYSTEMS
First Claim
1. A method for operating a vehicle camera system, the method comprising:
- receiving an image from a camera mounted on a vehicle;
calculating one or more metrics based on the received image;
determining whether a lens of the camera is contaminated based on the one or more calculated metrics;
determining a type of contamination;
selecting one of a plurality of mitigation routines to enhance the image based on the determined type of contamination;
applying the selected mitigation routine to create an enhanced image;
analyzing the enhanced image to determine whether the contamination is acceptably mitigated after application of the selected mitigation routine; and
outputting a fault condition signal when the contamination is not acceptably mitigated after application of the selected mitigation routine.

Abstract
Systems and methods are presented for operating a vehicle camera system to detect, identify, and mitigate camera lens contamination. An image is received from a camera mounted on the vehicle and one or more metrics is calculated based on the received image. The system determines whether a lens of the camera is contaminated based on the one or more calculated metrics and, if so, determines a type of contamination. A specific mitigation routine is selected form a plurality of mitigation routines based on the determined type of contamination and is applied to the received image to create an enhanced image. The enhanced image is analyzed to determine whether the contamination is acceptably mitigated after application of the selected mitigation routine and a fault condition signal is output when the contamination is not acceptably mitigated.

17. A method for operating a vehicle camera system, the method comprising:
-
receiving an image from a camera mounted on a vehicle; calculating one or more metrics based on the received image; determining whether a lens of the camera is contaminated based on the one or more calculated metrics; determining a type of contamination; determining whether the contamination renders the camera system effectively blind; generating a fault output signal when the camera system is determined to be effectively blind; determining a date and a time when the enhanced image is determined to be effectively blind; and storing the date and the time to a memory.
