摘　　要：针对常规测绘手段采集异型建筑物特征效率低、表达不完整的缺点,以南通某幢高层异型建筑物为例,采用三维激光扫描仪作为施工轴线检测数据采集设备,通过控制点布设、点云外业采集及点云内业处理对异型建筑物进行了施工轴线检测,并对其精度进行了评估,验证了三维激光扫描技术应用于异型建筑物施工轴线检测的可行性。Aiming at the disadvantages of low efficiency and incomplete expression in the collection of heteromorphic buildings' features by conventional surveying and mapping methods,this paper takes a tall and heteromorphic building in Nantong as an example. The 3D laser scanner is used as the data acquisition equipment to detect the construction axis by setting control points, collecting point clouds outside of the door and processing the data inside of the door. The accuracy is evaluated.As a result, the feasibility of 3D laser scanning technology in detecting the construction axis of heteromorphic buildings is verified.
