APPARATUS AND METHOD FOR TRACKING CAR

PURPOSE: A vehicle tracing method and an apparatus thereof are provided to accurately trace a vehicle region even in a difficult driving situation for accurately detecting the features of a vehicle. CONSTITUTION: A vehicle region detector receives multiple images from a camera module(S120) which puts a time lag between each received image. The vehicle region detector detects vehicle feature points from a first image(S130). The vehicle region detector extracts the optical flow of the vehicle feature points that exist between the first image and a second image(S140). The vehicle region detector traces the vehicle region based on the extracted optical flow(S150).
