基于RKT的管道测绘内检测检验点测量方法及系统
摘要：
本发明公开了一种基于RKT的管道测绘内检测检验点测量方法及系统，测量方法包括如下步骤：步骤一，获得基准站坐标并分析，将所得结果传送给移动站；步骤二，当基准站和移动站之间距离超过RTK测量范围时，使用基准站和移动站的同步技术重新获得高精度基准站坐标，继续RTK测量，本步骤进一步包括：基准站移动到移动站位置；在基准站和移动站距离很近时进行RTK的同步定位操作，利用移动站当前的高精度坐标，使基准站重新定位自己的坐标；同步后，移动站移动到下一个需要测量的地点；步骤三，获得移动站坐标。本发明保证了坐标测量精度，采用同步移动技术，保证整条管道的定位点坐标处于统一的精度区间，保障较高的开挖定位的复现率。
摘要（英）：

The invention discloses a pipeline surveying and mapping internal inspection checkpoint measurement method and system based on RKT. The measurement method comprises the following steps: step 1: obtaining the coordinates of a base station, analyzing the coordinates, and transmitting the result to a mobile station; step 2, when the distance between the base station and the mobile station exceeds anRTK measurement range, obtaining high-precision coordinates of the base station again by using the synchronization technology of the base station and the mobile station, and continuing the RTK measurement, wherein the step further comprises: causing the base station to move to the position of the mobile station; performing a synchronous positioning operation of the RTK when the distance between the base station and the mobile station is very small, and causing the base station to position its own coordinates again by using the current high-precision coordinates of the mobile station; and causing the mobile station to move to the next location to be measured after the synchronization; and step 3, obtaining the coordinates of the mobile station. By adoption of the pipeline surveying and mapping internal inspection checkpoint measurement method and system based on RKT disclosed by the invention, the coordinate measurement precision is ensured, it is ensured that the coordinates of the positioning points of the entire pipeline are located in a unified precision interval by using the synchronous moving technology, and a relatively high excavation positioning recurrence rate is guaranteed.
