Inter-vehicle distance measuring technique is widely used for Driving Assistance System (DAS) such as Adaptive Cruise Control (ACC) and Forward Collision Warning (FCW) which are useful for safety enhancement as well as driving convenience. In this paper, we propose a new method for providing accurate longitudinal inter-vehicle distance measurement by using a monocular camera and a line laser. Experimental results show that the proposed method outperforms the disparity-based method and the error in distance measurement is low enough even in nighttime as much as daytime.
