摘　　要： 以浑河流域模型为例,介绍利用三维激光扫描仪扫描模型获取点云的外业和内业工作,合理地选择和布设测站,并在各个测站对模型进行扫描以获取点云数据,对各个测站扫描的点云进行预处理,删除多余的孤立噪声点,将不同视图的点云进行拼接与配准,最后在同一空间坐标系内进行匹配。针对整体数据匹配,分析并应用基于闭合导线条件的整体误差分配计算方法。 Taking the model of Hunhe River as an example, the outaoor ano muoot w,, 5 sional laser scanner to get the whole landscape of point cloud of the river was introduced. First of all, choose and layout the survey stations reasonably. Then use three-dimensional laser scanner to obtain the data of point cloud on the surface of the river and delete unnecessary isolated point so as to simplify and pretreatment the point cloud. The images of different views were stitched in the same coordinate system. At last the views mentioned above were registered in the absolute coordinate system completely so as to reconstruct the model of the river.

关 键 词： 激光扫描 河道 点云 配准 匹配
