IMAGING SYSTEM AND METHOD FOR DETECTING FOG CONDITIONS

摘要

An imaging system and method is provided for detecting fog conditions surrounding a controlled vehicle. An imager having an image sensor is configured to image a scene external and forward of the controlled vehicle and to generate image data corresponding to the acquired images. A processor is configured to receive the image data and to receive additional information including at least one of an outside temperature, a windshield wiper speed, and a vehicle speed. The processor selects logic and/or parameters for detecting the presence of fog in response to the received additional information. The processor then analyzes the image data using the selected logic and/or parameters to detect the presence of fog and generates a signal responsive to the detection of fog.
