摘要
GPSRTK技术在三维数据采集中的应用越来越多,但在繁华城区内工作一直被认为是一个不可逾越的鸿沟,强遮挡问题、电磁波干扰问题、多路径问题、精度问题等使人们望而却步。本文通过沈阳市自来水管网图文信息系统建设项目将GPSRTK技术应用到繁华城区的数据采集,通过实际应用总结出,只要注意解决本文结论中提出的几个问题,GPSRTK技术不但可在繁华城区应用,而且能收到比较理想的结果。
The application of GPSRTK technique which is used in three dimension data capturing became more and more extensive,but it is deemed a impassable gulf that is used in the prosperous city area.It is strong occlusion,the interference of electromagnetic wave,excessive routing problems and precision that make people flinched.By the application building project with GPSRTK technique used data capturing in the tap water tube net of prosperous area of Shenyang city,the purpose is that if only people pay attention to the problems,GPSRTK technique may be used in the prosperous city area with satisfied precision.
