Method and apparatus for determining fail-safe of camera image recognition

A method of detecting soiling of camera image recognition, the method comprising:

• obtaining location information of the sun based on a current date and a current time;
• generating a straight line between the sun and a camera based on position information of the sun and location information of a vehicle;
• and
• determining whether an error occurs in image recognition of the camera based on the straight line, a capturing direction of the camera, and a moving direction of the vehicle.

An apparatus for detecting soiling of camera image recognition, the apparatus comprising:

• a processor;
• and
• a memory;
• wherein the processor is configured to:
• obtain an altitude and an azimuth of the sun based on a current date, a current time, and location information of a vehicle;
• generate a straight line between the sun and a camera in a three-dimensional space based on the altitude and the azimuth of the sun, and generate a lens surface of the camera in the three-dimensional space based on a moving direction of the vehicle and a lens surface angle of the camera;
• and
• determine that an error occurs in image recognition of the camera if the straight line passes through the lens surface.
