摘要
现有多波束测深系统采用RTK三维水深测量时,一般都是使用HYPACK、PDS2000、EVA、QINSY等商业软件进行外业采集后,内业通过CARIS、HYPACK、QINSY等软件自动进行潮位改正。商业软件在RTKS三维水深测量时外业设置比较烦琐容易出现问题,不易在后处理进行纠错改正,同时内业RTK水位异常检查也不方便、直观。本文通过外业直接采集RTK的WGS-84三维坐标数据,内业以Visual C#为开发工具,实现自动生成水深基准转换方案、RTK水位编辑处理及自动转换生成动态潮位文件,使用此动态潮位文件按照单站改正方式对多波束水深进行潮位改正,从而便捷、准确地实现多波束测深系统的RTK水位改正。此技术成功用于连云港赣榆10万吨级航道检测测量,从而进一步验证了此技术的可靠性。
Existing multi-beam sounding system using RTK three-dimensional depth Survery are generally use HYPACK,PDS2000,EVA,QINSY business software such as field collection,by data processing in the office through the CARIS,HYPACK and QINSY software automatically tidal correction. When the business software is used in RTK-DGPS 3 D water depth measurement,the external setting is rather complicated and is easy to appear problem.,not easy to correct errors in post-processing,RTK water level anomaly inspection in the industry also not convenient,intuitive. In this article,through field direct acquisition of RTK WGS-84 3 D coordinate data,based on Visual C# development tool in the industry,realize automatic generation of depth datum transformation scheme,RTK level editing process and dynamic water level automatic conversion generated file,use the dynamic water level documents in accordance with the single stand correct way of multi-beam sounding tidal correction,which is convenient and accurate implementation of the multi-beam sounding system of RTK level correction.This technique successfully used in Lianyungang Gan Yu-channel supervision inspection,further verify the reliability of this technique.
