摘要
车载GPS由于效率高、精度高、全天候作业、成本低等优点,在电子地图的道路信息采集与更新方面将逐渐取代传统的道路测量方法。根据所完成的道路修测系统,首先介绍了道路修测系统内业数据的编辑处理以及成图的主要内容,并针对利用车载GPS更新电子地图时,对道路修测系统中数据处理和添加入电子地图部分存在的一些问题及其解决办法进行了讨论,设计了相应的算法,最后利用某市某条道路上采集的部分RTK数据进行了验证。
Vehicle-born GPS, with the advantages of great efficiency, high precision, working all-day-around and low cost, will replace traditional road surveying in updating road information in electronic map. Based on the Road Surveying System completed, this paper introduced main work of data processing and updating map data in this system, and mainly discussed some problems in data processing by means of vehicle-born GPS in updating map data, designed relevant algorithm, and gave some test to validate the algorithm with RTK data of one road in the given city.
