机动车驾驶人场地驾驶技能考试系统算法设计

摘要

The efficient algorithm of vehicle body outlet was designed based RTK GPS in the field driving skill test system. The calculation method of line segment of intersection was introduced. There are many advantage in this way: few vehicle size measurement points, high efficiency, easy to realize in the micro controller with low cost, without the need for GPS to partition the field project. The construction period can be shortened and the efficiency of construction can be improved.%目前机动车驾驶人场地驾驶技能考试都是采用车载工控机进行软件算法的实现，其成本高，要求量取较多的车辆尺寸，且需要对场地项目进行区域划分，算法效率低。针对以上问题，设计了基于RTK技术的差分双GPS定位方案的车身出线及车辆压线的高效评判算法，该算法主要采用线段相交式的计算方法，通过实际场地测试，得出该算法对车辆尺寸度量点数少、运算效率高，易于在微控制器中实现，成本低，且无需对场地项目进行GPS区域划分，可以缩短施工周期、提高施工效率。
