| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系所 === 96 === Although side view mirrors can be used to assist the driver to determine if there is enough safe distance for lane change maneuvers, side collision accidents might still occur due to the existence of the blind spot or the inattention of the driver. In this thesis, a multipurpose digital signal processor (DSP) based blind spot warning system is implemented. The major research topic in this system is the blind spot vehicle detection warning systems by TI DM642 platform. The system has been applied in highways and urban roadways, and works well in sunny, cloudy, and rainy conditions for day and night. The day and night switch algorithm is used to determine time. The system performance can reach 20 frames per second with CIF format through the optimization technologies which are specially designed for the DSP platform. When the adjacent vehicle approaches to the host vehicle, the system will generate a warning signal to alert the drivers avoiding the collision.
