摘要
基于Arcgis软件的3D Analyst功能,探究无人船在水下地形测量中最优航带设计方案。使用克里金插值法模拟水下三维地形,用实测数据对不同航带宽度的模型结果进行精度分析,通过计算发现,无人船航带宽度为20m、30m、40m在实际工程应用中较为适用。结果表明,无人船水下地形测量可根据精度要求和工程预算选择40m以内合适宽度的航带。同等航行里程,常规航带比井字形航带的模型精度更优。
Based on the 3D Analyst function of Arcgis software, the Kriging interpolation method is used to simulate the underwater three-dimensional terrain, and the measured data is used to model the different belt widths. The results of the accuracy analysis, through calculations found that the unmanned ship’s voyage width is 20 meters, 30 meters, 40 meters is more suitable in practical engineering applications. The results show that the underwater terrain measurement of the unmanned ship can select a suitable width of the navigation belt within 40 meters according to the accuracy requirements and the project budget. With the same sailing mileage, the conventional navigation belt has better model accuracy than the well-shaped navigation belt.
