摘要
针对车载惯性导航设备由于其惯性器件随时间漂移产生误差导致系统定位精度逐渐变差的问题,提出了一种路网匹配定位方法以提高车载导航系统的综合定位精度,该方法基于视觉测量原理通过双目摄像装置采集道路周边环境特征进行匹配定位,介绍了匹配定位的基本原理和系统实现所需的关键技术,通过实际跑车测试,验证了该方法的合理性和可行性。
A new road-matching location method is proposed,to improve the positioning accuracy of vehicle inertial navigation system and solve the problem of positioning accuracy gradually deteriorated due to the error caused by inertia components precision changed with time. The method based on vision measurement theory and is assisted-positioned by roads surrounding environment which acquisitioned by two cameras. Environmental matching-position theory and key technology are presented,and the method’s correctness and feasibility are verified by long way road position testing.
