摘要
基于数字图像处理理论,提出了一种车间距离测试的方法,介绍了边缘增强与形态学处理相结合的图像预处理算法、阈值分割与判定树结合的障碍物检测方法以及反转透视测距计算模型,利用VC++平台编写了测距实验程序并组织了测距试验。试验结果表明,该测距方法简洁有效,能满足智能车辆测距工程需要,是一种可行的前方车辆距离测量方法。
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.
