摘　　要：在研究前方障碍物识别及高速公路几何模型基础上 ,对其左右边缘线的几何约束关系进行了讨论 ,分析了常用的多目测距算法的不足 ,提出了一种实时、有效地利用计算机视觉原理实现单目测距的求解高速公路上障碍物距离测算方法。实验证明 ,系统的实时性好 ,精度高 ,达到了实用要求。This article discusses the geometrical inter limited relation of edges of both sides on base of the investigation on the recognition of obstacle ahead and the geometrical model of the high way,analyzes the traditional methods of measuring distance by multinocular vision, and presents a real time and efficient calculation method which makes use of computer vision theory to realize the measurement of the distance of a obstacle in the high way by monocular vision.As the experiments show, the system has a good real time property ,high accuracy so as to measure up to the practical requirement.
