无人机倾斜摄影辅助三维激光扫描技术在厂房改造中的应用研究

Research of UAV Tilt Photography Aided 3D Laser Scanning Technique Applied in Factory Building Reconstruction

为解决厂房改造中站式扫描仪获取点云缺漏的技术难题,本文提出三维点云融合技术,采用站式扫描仪采集厂房墩柱、横梁、门窗的点云数据,同时使用无人机倾斜摄影获取建筑外立面信息,将两种测量成果进行融合得到厂房完整三维点云数据。实验表明,该三维点云融合技术提高点云数据的完整性,让设计图件绘制容易判读、尺寸更准确。

In order to solve the technical problem of point cloud acquisition by station scanner in plant reconstruction,this paper proposes three-dimensional point cloud fusion technology.The station scanner is used to collect the point cloud data of pier,beam,door and window of the plant,and the UAV tilt photography is used to obtain the building facade information.The two measurement results are fused to obtain the complete three-dimensional point cloud data of the plant.The experimental results show that the 3D point cloud fusion technology improves the integrity of the point cloud data,and makes the drawing of design drawings easier to interpret and the size more accurate.
