摘要
针对带GPS三维激光扫描仪在数据采集过程中,受到信号干扰的影响,无法完整准确获取三维数据的问题,文章采用不同设备相同数据源格式进行三维数据采集。结合手持三维激光扫描仪(BLK2GO)和移动背包扫描系统(Pegasus Backpack)对昆明市盘龙区双龙街道哈马者小组房屋进行三维数据采集。以移动背包扫描系统点云数据为基础,融合手持三维激光扫描仪点云数据,得到测区目标物完整的三维点云,并进行数字化成图。实践证明,这两种系统的结合可为GPS信号弱的测区类似工程的数据采集提供参考。
In view of the problem that the 3D laser scanner with GPS is unable to obtain 3D data completely and accurately due to the influence of signal interference in the process of data acquisition,this paper adopts the same data source format for 3D data acquisition with different devices.Combined with handheld 3D laser scanner BLK2GO and mobile backpack scanning system Pegasus Backpack,the 3D data collection of house information in Hamazhe group,Shuanglong Street,Panlong District,Kunming City is carried out.Based on the point cloud data of mobile backpack scanning system and the point cloud data of handheld 3D laser scanner,the complete 3D point cloud of target in the survey area is obtained and digitized.Practice shows that the combination of these two systems can provide some references for data acquisition of future similar projects in the survey area with weak GPS signal.
