城市十字路口汽车防撞信息系统优化

Optimization of the Automobile Anti-Collision Information System in Urban Crossroads

介绍和分析了城市十字路口汽车防撞信息系统的框架,对机器视觉的关键技术车道检测和障碍物检测的难点进行了详细的分析。与雷达等传感器相比,机器视觉具有低造价、低能耗和利于车载等优点,更适合用于车辆的外界感知系统,同时也指出了其不足之处,为机器视觉的发展提供了方向。

The framework of the anti-collision information system in urban crossroads is introduced. Detailed analysis is carried out on the difficulties of machine vision essential technical traffic lane examination and obstacle examination. Compared with radars or other sensors, machine vision has the merits of low cost, low energy consumption and convenient carrying, etc. It is especially suitable for sensation system of the exterior vehicle. Its disadvantages are pointed out. It provides the direction for the development of machine vision.
