Weather identifying system based on vehicle video image

Aim at the influence of the weather factor upon the road vehicle, this paper puts forward a kind of a weather identifying system vehicle video image. The system needs to initialize an original background image which is the brightest on the average in the first period of time. The background image is renewed not only when the bright degree of next frame image is higher than it, but also the weather is detected sun day at the same time. Get a background image of the current video sequence and let it minus with it to obtain the identifying image. At last do texture analysis to it to realize the weather automatically identifying. This paper mainly identifies the weather in a sun day, cloudy day and snow day, and after a lot of experiments the method are proved to be effective, and it can identify the weather condition of the current vehicle video accurately.
