摘　　要：受到周边环境的遮挡与影响,导致传统的建筑立面提取方法存在提取数据丢失以及提取效率低的问题,为此提出基于大功率激光投影的建筑立面提取方法。首先分析建筑立面结构,确定立面提取目标。安装大功率激光投影设备,并利用该设备采集建筑立面点云数据,根据激光的特殊性质解决环境遮挡的问题。对初始点云数据进行预处理,并从轮廓边界、立面高度等方面得出建筑立面的提取结果。通过对比实验得出结论:与其他两种方法相比,设计方法提取数据的完整性提高了1.3%,且消耗的提取操作时间较少。Due to the occlusion and influence of the surrounding environment,the traditional building facade ex-traction method has the problems of data loss and low extraction efficiency.For this reason,a building facade extraction method based on high-power laser projection is proposed.First,analyze the building facade structure and determine the facade extraction target.Install high-power laser projection equipment,and use the equipment to collect point cloud data of building facades,and solve the problem of environmental occlusion based on the special properties of the laser.The initial point cloud data is preprocessed,and the extraction result of the building facade is obtained from the outline boundary and the elevation height.Through comparative experiments,it is concluded that compared with the other two methods,the designed method improves the data integrity by 1.3%and consumes less extraction operation time.
