Imaging system including dynamic compensation for color attenuation for vehicle windscreens

摘要

An imaging system for a vehicle is disclosed having an image sensor positioned in the vehicle for capturing images through a windscreen of the vehicle and for generating image data corresponding to the captured images, and a processor coupled to the image sensor for receiving and analyzing the image data and detecting vehicle light sources in the captured images. The processor: detects a predetermined number of vehicle light sources; averages color values of each detected vehicle light source; determines differences between the averaged color values and target color values; and stores the differences as color compensation values. A vehicle equipment control system is further disclosed having the imaging system above, wherein the processor compensates color values of subsequently detected vehicle light sources and generates a control signal that is used to control the vehicle equipment in response to the detection of color compensated vehicle light sources in the captured images.

1. An imaging system for a vehicle comprising:
an image sensor positioned in the vehicle for capturing images through a windscreen of the vehicle and for generating image data corresponding to the captured images; and a processor coupled to the image sensor configured for receiving and analyzing the image data and detecting vehicle light sources in the captured images, wherein the processor is further configured to: (a) detect a predetermined number of vehicle light sources; (b) average color values of each detected vehicle light source; (c) determine differences between the averaged color values and target color values; and (d) store the differences as color compensation values to compensate color values of subsequently detected vehicle light sources.
