| 摘 要： | 根据海道测量定位数据后处理的要求,对定位数据后处理中的拟合算法进行了研究,提出了一种基于多面函数拟合的后处理方法,并给出了相应的数学模型。实例结果表明,后处理中采用多面函数拟合法处理测线定位数据可提高定位数据的可靠性,拟合精度可将精密动态定位控制在厘米级。上述方法有利于提高海道测量中海上定位成果的质量。 |

| Abstract: | In terms of the requirement on the positioning data post-processing in hydrographic survey,a new method for the positioning data post-processing,based on multiquadric fitting,is presented in this paper.The results show that,in the data post-processing,the quality of the positioning data can be improved by the multiquadric fitting and the precision can achieve the center meter level.The implement of new method is in favor of improving quality of the positioning achievement for hydrographic survey. |
| Keywords: | hydrographic survey post-processing multiquadric fitting node selection |
