This paper, according to the physical model and optic model of rain drops, analyzes the affect of rain drops on the light strength of single -frame images in video firstly, detect the rain drops in video by time difference method of Nayar, and then make improvement for the need of more intensive rain drops. Addition to this method, it also classifies the rain drops according to their different time and places by K-means clustering method. At last, it compares the real time, advantages and disadvantages of these two methods. As a result, these two methods are proved to be effective.
