摘要
介绍了车载终端组合定位原理,提出检验终端定位精度的几种方法,包括静态定位检验、动态定位检验、一般性检验等.对终端做了模拟真实场景的实验,通过对静止状态定位、遮挡环境定位、路测等实验数据处理后与高精度数据进行对比,计算出终端定位的均方根(RMS),并将定位数据匹配到电子地图上,展现了良好的定位和地图匹配成果,基于理论、实验和数据分析,得出组合定位终端定位精度满足实际应用要求的结论.
The principle of vehicle terminal combination positioning is introduced,and several methods for verifying the positioning accuracy of positioning of the terminal are proposed,including static positioning test,dynamic positioning test and general inspection.Experiments were carried out on the terminal to simulate the real scene.The experimental data of static state,occlusion environment,and road test were processed and compared with highprecision data to calculate the RMS"root mean square"of the terminal location(Root Mean Square).RMS),and matching the positioning data to the electronic map,showing good positioning and map matching results,based on theory,which conclude that the accuracy of terminal positioning meets the requirement of practical application.
