The present invention relates to video-based driver assistance systems being used in vehicles today to perform a variety of functions, such as lane or road departure warning. These functions often require that parts of the video image be identified as, for example, a traffic sign, a bridge, lane markings, etc. Particularly the present invention relates to a method for video image-based weather and/or road condition detection. A method and a system is described, according to which method, weather and/or conditions are detected by identifying bright pixels or groups of bright pixels in video images and by deciding whether or not said bright pixels are caused by reflections, due to rain- or snowfall, and/or due to a wet or snowy surface. Also a computer program product is described, stored on a computer usable medium comprising computer readable program means for causing a computer to perform such a method, wherein said computer program product is executed on a computer. |
