摘要
本文采用机载LiDAR与倾斜摄影技术融合方式进行村落现状信息的采集工作。机载LiDAR技术能够快速有效地采集测量区域的点云数据,为倾斜摄影提供控制点,对部分由于遮挡而生成的倾斜摄影点云空洞进行点云补充,进而提高三维模型质量。机载LiDAR技术可以部分穿透植被,得到植被下点云数据,进而可生产高精度的DEM数据。对于较为狭窄的房屋间空隙,机载LiDAR点云可以为倾斜模型修复提供数据支撑的同时也可以作为房屋立面测量的基础数据。通过机载LiDAR技术与倾斜摄影技术的融合,为美丽乡村建设村落现状信息的获取提供新的方法。
Airborne LiDAR and tilt photography technology were used to collect the information of village status.Experiments show that airborne LiDAR technology can quickly and effectively collect the point cloud data in the measurement area,provide control points for tilt photography,repair the point cloud holes in tilt photography partly due to occlusion,and improve the quality of 3 D model.Airborne LiDAR technology can partially penetrate the vegetation to obtain the point cloud data under the vegetation,and then produce high-precision DEM data.For relatively narrow spaces between houses,airborne LiDAR point clouds can provide data support for tilt model repair and also serve as basic data for building facade measurement.Through the integration of airborne LiDAR technology and tilt photography technology,this will provide a new method for obtaining information on the status quo of beautiful rural construction villages.
