高精度GPS/GIS定位技术在机动车道路考试系统中的应用研究

摘要

在计算机化的机动车驾驶人道路考试系统中,为了实现骑压中心实线等与车辆位置有关的评判项目的自动评判和路口处车辆行驶方行驶自动导航,需要精确、实时定位考试车辆的位置.高精度的GPS/GIS技术能够很好地实现考试车辆的定位问题.论文首先介绍了高精度的GPS/GIS技术的实现技术,然后详细分析了考试车辆的车辆形状建模模型和车辆行驶方向判断方法,最后给出了机动车道路考试系统中与车辆位置有关的评判项目的自动评判实例.%It is necessary to locate the real-time position of the motor vehicle precisely in order to achieve the automatic-navigation and the automatic-evaluation of the test items relating to the position of motor vehicle, such as the item of cross-road center line in the road test system. It is an excellent technology to locate the motor vehicle with high precision GPS/GIS. In this paper, the technology of high precision GPS/GIS is introduced, and the motor vehicle's shape model is built. Then, the method of judging driving direction of motor vehicle is put forward. Finally, the automatic evaluation examples relating to the motor vehicle position in road test system is presented.
