摘　　要：三维激光扫描技术能快速、大面积地获取被扫描物体表面的三维点云数据,具有高效率、高精度的独特优势。借助某工程模型试验,将该技术应用于模型库区泥沙冲淤形态的测量,克服了常规地形测量方式的局限性,在保证测量精度的同时节省了时间和人力。同时,结合后处理软件,实现了等高线绘制、冲淤形态对比和排沙量计算等试验数据分析及成果展示。3D laser scanning technology has advantages in collecting three-dimensional point cloud data from the surface of the scanned objects with high efficiency and precision. So any small changes of objectssurface can be reflected accurately. It used this technology to overcome the limi-tations of common measuring methods in topographic survey of sediment erosion and deposition. It saved much time and manpower with holding the measurement accuracy. Meanwhile,with the help of various post-processing software,it provided more comprehensive and diverse way of data anal-ysis and presentation,like drawing contours,contrast of scouring and silting,calculating sand discharge capacity and so on.
