Abstract:
The present invention relates to a vehicle collision warning system and a method therefor. The method of the present invention comprises: a step for preprocessing the image obtained from a camera module attached to a user's automobile into an integral image; a step for detecting a vehicle candidate region by applying the AdaBoost algorithm to the integral image while adjusting the size of a vehicle detection window within a predetermined range; a step for verifying whether the detected vehicle candidate region is a valid vehicle region; a step for determining a vehicle region corresponding to the vehicle in front by clustering the verified valid vehicle regions; a step for finding the distance from the vehicle in front and the user's automobile by using the determined vehicle region; a step for deciding vehicle collision warning conditions when the distance between the vehicle in front and the vehicle of a user is below the predetermined standards; and a step for generating a vehicle collision warning when the vehicle collision warning conditions are met.
