长测程地面三维激光扫描仪在古建筑物特征信息提取中的应用研究

Application of Long Range Terrestrial 3D Laser Scanner in Extracting Feature Information of Ancient Buildings

针对传统古建筑测量方式存在的效率低、精度差以及无法可视化等问题,将长测程三维激光扫描仪应用于古建筑测绘工作中,同时获取古建筑物表面海量的三维坐标数据、材质信息和纹理信息,作业时无需接触古建筑实体表面,能够有效保护作业人员以及古建筑本身结构的安全,避免古建筑本体二次损害,为古建筑的底图存档、改造修缮提供全方位立体式测量模式。

Aiming at the problems of low efficiency,poor accuracy and inability to visualize in the traditional measurement methods of ancient buildings.In this paper,long-range 3D laser scanner is applied to the surveying and mapping of ancient buildings.It can simultaneously obtain massive 3D coordinate data,material information and texture information on the surface of ancient buildings.There is no need to touch the solid surface of ancient buildings during operation,which can effectively protect the safety of operators and the structure of ancient buildings and avoid secondary damage of ancient buildings.It provides a comprehensive three-dimensional measurement mode for the archiving,renovation and repair of the base map of ancient buildings.
