Abstract: A hardware platform, a computer vision-based vehicle safety system was proposed, taking TI's DaVinci chip as the core processor and taking the embedded Linux in conformity to hardware configuration as the software development platform. The system was provided with some functions, including overspeed warning, vehicle distance judgment, accident assistance, vehicle position determination and vehicle anti-theft. Highway test results show that the missing rate of the algorithm is less than 5% and the false detection rate is less than 0.5%. Due to small size, low power consumption, high usability, high expansibility and upgradeability, this system can be widely used in various vehicles.
