摘　　要：简要介绍了现行的部分国内外多波束测深数据异常值检测算法,比较和分析了算法的各自优缺点,包括中值滤波、基于趋势面的测深异常检测、抗差估计异常值检测。总结得出,通过综合利用以上各种算法,能有效提高测深数据的异常值检测效果。The paper introduces the current algorithms of processing outliers of multibeam bathymetry data both here and abroad. The algorithms are compared and analyzed. They include median filtering, trend surface detection, and robust estimator. The wavelet transformation steps are advanced and analyzed in feasibility. At the end of paper, the summary that synthesizing some algorithms above will improve the effect more obviously is got out.
