摘　　要：为消除水下冲刷多波束数据的显示隐藏问题,提出一种结合区域隔离和调整数据色谱阈值的模型尺度调整算法,并给出基于该算法的数据处理方法。实例分析表明,采用基于模型尺度调整算法的数据处理方法,可使多波束数据成像显示效果提高3~5倍,从而解决水工建筑物水下冲刷数据的显示隐藏问题。To reduce the data-hidden issue for multi-beam data of underwater scour region,a new model-dimension adjustment algorithm was introduced,in which the regional isolation and data chromatography threshold adjustment was combined,and the postprocessing method was also provided.Casestudy indicates that this new approach can improve the imaging performance for multi-beam bathymetry surveying data 3 to 5 times.Therefore,the hidden phenomenon of underwater scour datafor hydraulic structures is solved.
