摘要
对CUBE算法自动处理多波束测深数据的模型建立、格网节点的多重估计和最优估值选取准则进行了详细介绍,深入分析了多重估计的实用性,并通过实测数据对该算法进行实现。利用了抗差Kalman滤波改进CUBE算法。通过模拟数据对改进的CUBE算法进行实验,验证了算法改进的必要性。
The CUBE algorithm in automatic processing multibeam bathymetry data is introduced in detail by its model construction,multiple estimations of grid node and the rules of selecting best available estimation.The efficiency of multiple estimations is analyzed intensively,and the algorithm is implemented using multibeam real data.The Robust Kalman filter is presented to improve the CUBE algorithm.The improvement of the algorithm is compared by the experiment of synthetic data,and its necessity is showed.
