【Abstract】 Based on the digital image processing theory,a new method of measuring the leading vehicle distance was proposed.The input image using the method of edge enhancement and morphological transformation was established.The result of obstacle detection by segmentation and decision tree was also acquired.At last,the leading vehicle distance based on the calculating model of inverse perspective mapping was measured.Through using software VC++,an experiment program was made.The experiment results prove that the method of measuring the leading vehicle distance is simple and effective.It can meet the requirement of intelligent vehicle technologies.It is an available method to calculate the leading vehicle distance.更多还原
