This paper proposes a vehicle tracking method for the Forward Collision Warning System (FCWS). The proposed method applies vehicle detection and feature tracking to each frame in the videos to enhance the detection accuracy and increase the stability of vehicle localization. The proposed method can be applied to three-lane FCWS which includes left, main, and right lanes. The performance of the proposed three-lane FCWS can achieve 720x480 video@183 fps in average when realized in PC with Intel Core i7 processor with average detection accuracy of 94.05% at daytime and 86.90% at night. The proposed method is also implemented on Freescale i.MX6 embedded platform with a USB webcam to capture the video. Under the D1 (720x480) resolution, the performance of the proposed 3-lane FCWS can achieve 29 fps.

This paper presents a vision radar system (VRS) integrating Lane Departure Warning System (LDWS) and Forward Collision Warning System (FCWS) for car safety driving applications. A dynamic threshold, which improves the accuracy of lane and vehicle detection in various weather conditions, and multiple frame approval, which conquers the effect of some tough scenes, are proposed. The designed radar-map facilitates warning message issuing of safety distance for forward and potential cutin vehicles. The proposed VRS can achieve 22 fps at 720x480 (D1) resolution on Freescale i.MX6 embedded platform.
