摘要
用RTK采集数据,受卫星状况、天空及周边环境、数据链传输等影响,许多地方数据难以采集。全站仪作业时,视线遮挡使得个别点数据需要多次搬站才能采集,劳动强度大,作业效率低,精度难以保证。RTK和全站仪联合采集数据,利用RTK效率高、精度好、误差不积累、数据处理快等优势,随时为全站仪设置测站,克服全站仪的不足,同时用全站仪的优势来弥补RTK的劣势。本文通过实例介绍RTK和全站仪联合采集数据应用于生产的作业流程,分析图根点与碎部点数据采集、分离和处理的方法。分离后的图根点数据以原始测量数据形式参与平差,获取图根点坐标。碎部点数据经处理后以*.dat格式输入计算机编辑成图。该方法避免了作业员重复进入同一作业区域,达到了优势互补,简化程序,减少误差,提高效率,保证精度,节省人力和物力的目的。
It is difficult to collect data by using RTK in many places due to the influences of the satellite status, the sky, the surrounding environment, the data chain transmission and so on. It needs to change the station to gather data when the individual points are kept out with Total Station, which leads to the big labor intensity, the low work efficiency and precision. With the combination of RTK and the Total Station to gather data, this paper makes full use of advantages of RTK and total station, such as RTK's high efficiency, good precision, absence of accumulative error, and quick data processing, which can overcome insufficiency of total station and establish survey station when needed. Simultaneously, it is obvious that total station's superiority can make up RTK's inferiority. The paper describes the workflow of such principle, and analyses the method of gathering, dispatching and disposing the controlling points and scattered points. As original surveying data, the dispatching controlling points are used in survey adjustment to get controlling-point coordinates. And processed scattering points are input with .dat format to the computer to mapping. This method avoids the operator's repeated entrance to the identical task area, and achieves superiority supplementary, simplifies the procedure, reduces the error, enhances the efficiency, guarantees the precision, saves manpower and physical resource.
