一种车辆移动位置和姿态的精确测量方法

摘要

驾驶人场地驾驶技能考试需要实时检测考车在场地中的位置及其与场地标志、标线、测试物之间的距离,针对这一要求,本文基于RTK GPS定位技术,采用二点定位法,对考车的位置和姿态进行精确测量,进而求出考车车身上任意一点的位置,结合测绘得到的考场电子地图,求出考车车身与场地上任意一点的距离,实现场地驾驶技能考试的自动检测.本文给出该方法工作原理和具体应用.%To satisfy the precisely distance measure between a moving vehicle and a field sign or a road marking or a object used for testing,this paper proposes two-points positioning based on RTK GPS.The positioning implements a precisely measure of the position and attitude of a moving vehicle,computes the position of any point of the vehicle body,combined with the field electronics map surveyed,finally acquires the precise distance between a point of the vehicle and a point of the field.The positioning realizes the automatic detection of the field driving test and its operation principle and applications is introduced.
