摘要:
全球定位系统(GPS)因其高精度三维定位测速及定时的功能在精密工程测量中得到迅速广泛的应用。利用高精度GPS载波相位实时动态差分(RTK)定位技术的特点，在机动车驾驶技能考试中，可精确地计算考车的轮廓位置点，解决了考车行驶过程中的距离测量问题。根据RTK技术在考车上架设的双GPS天线和具体考试项目里车线之间距离的检测方法，并结合考场电子地图各项目的特征点和各项目的评判规则，华众设计的全自动智能驾考系统，可实现精确评判。
Global positioning system (GPS) has been widely used in precision engineering measurement be-cause of its high precision three dimensional positioning velocity test and timing function. Using the characteristics of high precision GPS real-time kinematic (RTK) positioning technology in the motor vehicle driving skills test can accurately calculate the contour points of the test vehicle, this solves the problem of distance measurement in the course of test vehicle. Based on RTK Technology in the test vehicle mounted dual GPS antenna and the detection method of the distance between the test vehicle and the line in the examination of specific project, and combined with the examination of electronic map the feature points and the purposes of evaluation rules, Huazhong design the automatic intelligence of the driving test system , which can realize accurate judgment.
