摘要
为快速、准确地同步采集陆地及水下三维点云,构建船载激光三维扫描系统,集成三维激光扫描仪、多波束测深仪和光纤罗经等设备,介绍系统组成及其工作原理,总结了系统的关键技术,应用于北江某河段三维一体化测量,获得了精细的陆地水下一体化点云模型,与常规测量进行对比并统计了数据精度。结果表明,船载激光三维扫描成果精度满足规范要求。
In order to quickly and accurately collect data on land and underwater synchronously, a ship-borne 3D laser scanning system has been built which integrates three-dimensional laser scanner, multibeam echosounder and optic fiber gyro compass and so on.components, working principles and key techniques of the system are introduced delicate integrated point cloud model is got, and data collected by this system are compared with data collected in normal way. Finally, statistical data shows that the former data accuracy meets requirements of related specifications.
