摘　　要：多波束测深系统采集的是点云数据,数据量浩大,实际应用中一般只需要提取特征点数据。为了提高多波束数据筛选效率,使用ArcGis Engine平台编写程序进行二次开发,先利用点云数据建立高程模型,再套用历史或任意断面线(航线),在模型中自动按点距提取断面线(航线)中三维点,并对关键拐点加点,按单波束水下测量模式快速提取地形点,可方便绘制水下地形图和断面图。Multi-beam sounding system collects point cloud data with huge amount of data.Generally,only feature point data need to be extracted in practical application.In order to improve the efficiency of multi-beam data filtering,this paper uses ArcGis Engine platform to write programs for secondary development.First,we build an elevation model using point cloud data.Secondly,we apply historical or arbitrary section line(route)to automatically extract three-dimensional points from the section line(route)by point distance in the model,and add points to key inflection points to quickly extract terrain points according to single-beam underwater measurement mode.It is easy to draw underwater topographic and sectional maps.
