三维激光扫描仪在特殊地貌测量中的应用研究

The Application Research of Terrestrial 3D Laser Scanner for Special Landforms Mapping

三维激光扫描仪作为一种非接触数据采集设备,在特殊地貌的大比例尺地形测绘中有着广泛的应用前景。本文以草原石城景区为例,阐述了三维激光扫描仪在这种特殊地貌测绘中的应用原理,数据拼接和配准的方法,并与全站仪全野外数字采集的成果进行了高程和平面坐标的比对,证明了使用三维激光扫描仪测绘特殊地貌精度高、速度快,地貌表达逼真,为特殊地貌区域的大比例尺地形图测绘提供了新的技术手段。

As a non- contact data collecting instrument,terrestrial 3D laser scanner can be applied in special landform mapping and be broad prospects. The paper elaborates principle of special landform mapping and method of data merging and matching in the special landform mapping. The accuracy of result is compared in Height and Coordinate between terrestrial 3D laser scanner and total station. It proves that special landform mapping can be completed and expressed real topography with high accuracy and quick speed by terrestrial 3D laser scanner. A new technic is provided for large- scale mapping of special landform area.
