Glass surface raindrop detection using a camera and lighting
2013
The present invention relates to an apparatus and method for recognizing a rain (4). Apparatus for recognizing 該雨 an image sensor (5) and a plurality of filter colors for the pixels of the image sensor (R; G; B) camera equipped with a color filter comprising, as well as the first filter primaries It encompasses an illumination light source (3) for generating monochromatic light (h). The single color light is transmitted through the first filter primaries, the other filter colors belong to a wavelength region of visible blocked. The camera, as well as the illumination light source (3), said camera, the illumination light source is configured to be able to capture the signal of glass monochromatic light that illuminates the (2) (r1, r2 '), disposed It is.
