Abstract
The objective of this study is to construct the rear-end collision avoidance and warning system of advance safety vehicle (ASV) by rear-end parking camera. Based on image processing technology to get and analyze the driving environmental data, we developed the rear-end collision warning logic and system.ince the automobile electronics industry developed faster, the parking assist system, like the ultrasonic sensors and rear-end camera, almost become the basic equipment in vehicles. However, the parking assist equipments are only turned on when in parking mode. Therefore, to provide the following vehicle information for subjective one, this study tends to apply the rear-end camera in vehicle when moving forward. It not only reduces the equipment cost of the vehicle but also increases the safety for drivers.he main idea of warning system is to prevent accidents which caused by inattentive of drivers. This study used the image processing to detect the longitudinal data of the following vehicle, including the relative distance, velocity, and acceleration. We developed the dynamic thresholds by the relative data and the drivers’ perceptive reaction time to issue the warning signal for drivers. The α-β-γ filter was applied in this section to get the smoother relative data.his study built up a rear-end collision avoidance and warning system by rear-end camera. We constructed the warning program by Borland C++ Builder. The warning hardware of the system was used the industry personal computer and on-board video equipment. The experiment result was successful for the off-line video test. In other words, this study proves that the developed rear-end warning system could appropriately issue the warning signal for drivers.
