摘　　要：古建筑测绘是保护和传承历史文化遗产的重要工作之一。针对古建筑测绘中单独采用三维激光扫描技术或者无人机倾斜摄影测量难以采集到完整的古建筑数据的问题,本文协同三维激光扫描与倾斜摄影测量技术开展古建筑测绘。首先,利用三维激光扫描仪对古建筑进行全方位的快速采集,获取建筑物的三维点云数据;然后,通过无人机进行倾斜摄影,获得建筑物外部的高分辨率影像;最后,将这两种数据进行融合处理,实现对古建筑的全方位、精准测绘。试验结果表明,基于三维激光扫描与无人机倾斜摄影的古建筑测绘方法具有较高的测绘精度和效率,能够为古建筑的保护和修复提供重要的参考依据,在古建筑测绘领域具有良好的应用前景和推广价值。Surveying and mapping of ancient buildings are important tasks for protecting and inheriting historical and cultural heritage.In response to the difficulty in collecting complete data of ancient buildings by using three-dimensional(3D)laser scanning technology alone or unmanned aerial vehicle(UAV)oblique photogrammetry in surveying and mapping of ancient buildings,3D laser scanning and oblique photogrammetry were jointly used to carry out surveying and mapping of ancient buildings.Firstly,a 3D laser scanner was used to quickly collect the 3D point cloud data of ancient buildings in all directions.Secondly,a UAV was used for oblique photography to obtain high-resolution images of the exterior of the buildings.Finally,by integrating these two types of data,comprehensive and accurate surveying and mapping of ancient buildings were achieved.The experimental results show that the surveying and mapping method of ancient buildings based on 3D laser scanning and UAV oblique photography has high surveying and mapping accuracy and efficiency,which can provide an important reference for the protection and restoration of ancient buildings.It has good application prospects and promotion value in the field of surveying and mapping of ancient buildings.
