无人船测深系统在浅水河道测量中的应用

针对传统测深方法在浅水区测量实施困难的问题,基于无人船测深系统的组成及原理,重点研究了无人船姿态对测深的影响、测深数据粗差探测与滤波方法。分析得出:无人船姿态在浅水区对测深的影响有限,可采用中值滤波、加权平均法、趋势面滤波方法进行测深数据粗差处理。结合项目应用,证实无人船满足浅水河道测量需求、测深精度满足规范要求,可为类似工程提供借鉴。

Application of unmanned boat sounding system in shallow water channel survey

For the difficulty of the traditional sounding method in shallow water areas, based on the composition and principle of the unmanned boat sounding system,we studied the influence of the attitude of the unmanned boat on the sounding,and the method of gross error detection and filtering of sounding data. The analysis shows that the influence of attitude in shallow water area on depth sounding is limited,and medium filtering method,weighted average method,and trend surface filtering method can be used to process the gross error of sounding data. Combined with the application of the actual project,it is proved that unmanned boat systems can meet the demand of shallow water channel surveys and the accuracy of sounding can meet the specification requirements,which can provide a reference for similar projects.
