| 摘 要： | 受声线弯曲的影响,多波束测深的边缘波束的数据质量较低,而单波束测深受声线弯曲的影响比较小。结合多波束覆盖面大和声速剖面误差对单波束影响相对较小的特点,研究了多波束和单波束的测深数据融合方法,利用同一位置单波束和多波束测深数据的差值,拟合一个与坐标位置相关的误差模型,并利用该误差曲面对多波束测深数据进行综合改正,从而提高多波束测深的数据质量。

| Abstract: | Affected by the acoustic wave bending,the marginal beam data quality of the multi-beam system is low,but the influence of measurement by single-beam acoustic wave bending is relatively small.This paper studies a data fusion technique to fuse both the multi-beam and single beam data,combining the characteristics which has minor influence of multi-beam system coverage and sound velocity profile error on single beam,fitting out a coordinate position relevant error model,and utilize it to correct the surveying data and improve the data quality of the multi-beam bathymetric. |
