摘　　要：本文总结分析了CUBE(Combined Uncertainty and Bathymetry Estimator)算法的关键步骤和基本理论模型,实现了基于CUBE算法的多波束水深异常值剔除,并针对中国某海区的多波束实测数据,通过构建海底DTM(Digital Terrian Model)图,对比分析了CUBE算法与传统的手工作业方法的性能差异。实验证明:与手工作业方法相比,CUBE算法具有工作效率高、不受人为因素影响等优点。This paper summarized and analyzed the key steps and the basic theoretical model of the CUBE algorithm,eliminated outliers of Multibeam Echosounder(MBES) data based on the CUBE algorithm.The performance differences between the CUBE algorithm and the traditional manual approaches were compared utang seabed DTM constructed by MBES data in a sea area of the China Sea.The experiment showed that the CUBE algorithm was significantly faster and less subjective than the manual approaches.
