Car Distance Detection with Fast Camera Calibration for Vehicle Active Safety System

Vehicle Active Safety System is a popular subject of Intelligent Transportation System. Various types of sensors and techniques were used to collect surrounding information to help human beings drive safely. The objective of this research is to develop an intelligent Driver Assistance System. A monocular camera was used in a car to collect the road scene in front of a moving host car. The recorded road scenes were simultaneously analyzed to obtain useful information such as land markings and the nearest front car to aid driving. In order to precisely estimate the distance from the nearest front car to the host car, a real-time calibration method for machine vision was proposed based on the location of vanishing point. The experimental results show that the proposed method functions effectively and very well
