摘要
目前海底浅层声学剖面系统获取的空间数据成果缺乏直观、形象的表达方式,仅以二维图表形式提供海底浅层沉积物信息,文章结合相关可视化技术,基于浅地层声学剖面空间数据特征,提出了基于IDL体绘制的海底浅层空间三维可视化方法,取得了较好的表达效果。
The spatial result data acquired by marine sub bottom profiler lacks of intuitive representation method,and only could provide the information about marine sediment in two dimensional graphic.Combined with the related visualization technology and based on the characteristics of sub bottom acoustic profile spatial data,a 3D representation based on IDL volume rendering were proposed,which has gotten a good rendering results.
