Laser scanning from heights

激光扫描在近年来彻底改变了测量专业。有可能在相对较短的时间内捕获大量数据，3D激光扫描仪必须是用于收集数据的工具，以产生从简单地形调查到3D模型的输出，以保护文化遗产。

作为流程数字化和企业数字化，世界各地的测量师公司，喜欢Scan&Go, are adapting new technologies to offer better, faster and more specialised services to their clients. In collaboration with Leica Geosystems, Scan&Go, an Italian company leader in the field of topography and 3D high-definition survey, performed a functional test of its vehicle/tripod installation for 3D laser scanning using theLeica RTC360 3D laser scanner。

实现A.更快，更有效地使用陆地激光扫描仪, Scan&Go creates systems that can be installed on any type of vehicle or on a pneumatic pole to allow easy movement between scan sessions and ensure greater measurement range.

安装在扫描＆go system上，rtc360捕获2 million points per secondthe centre of Castelvetro di Modena, Italy, in only a few minutes. The Scan&Go team mounted the RTC360 on Scan&Go’s level lift roof and automatic LP16R leveller. For the first scan, the team captured the centre of Castelvetro di Modena from a3米高。The remaining three scans were done at a从地面6米的高度使用扫描和转向车辆安装。

“扫描仪的高度允许克服存在的障碍物并提高扫描范围及其测量的准确性，”explained Cristina Valchuk, sales manager at Scan&Go.“所有扫描都是完美的升级 - 这消除了垂直变化。我们对所做测试的满意度非常高。这种方法确保了操作员的安全和现场仪器，并提高了RTC360的生产率。“

测试的目的是验证新RTC360的潜力与移动“停止”和“GO”模式中的激光扫描的扫描和转储系统相结合with the instrumentation installed on the vehicle. The Scan&Go team also wanted to test the纠正视觉惯性系统的功能（VI），在现场进行自动点云注册，速度高于步行脚的速度。点云收集在一个车速范围从10到20公里在实时注册的团队令人惊讶。

“用RTC360获得的结果非常好。在扫描期间，系统非常稳定，确保最大测量精度，“瓦丘克说。“It is very fast because the 3D laser scanner is mounted on the vehicle and you do not have to disassemble anything during the movements between one scan and the other.”

从原始数据到智能数据

Point clouds are only a set of data points in space until stakeholders can visualise and interact with them. 3D models obtained from the point clouds help to inform the perception of reality and provide a georeferenced digital base for operations. Scan&Go creates 3D models for their clients so they can document, manage, renew or maintain any assets or environments. After post-processing data with旋风寄存器360.，专家创建了Castelvetro di Modena的3D模型。

考虑到简单且高度自动化的工作流程设计RTC360解决方案使用边缘计算将扫描数据流在平板电脑上实时流and automatically processes the scan data to provide实时质量控制和该字段中的数据登记。

和自动预注册，高质量的点云立即可用于扫描和去团队。在平板电脑上运行的Cyclone Field 360移动应用程序也在现场进行质量保证和完整性检查。这减少了该字段中数据捕获过程的复杂性，并在现场和办公室中保存了团队成员时间since they were able to leave the project site with a pre-registration that can be finalised in Cyclone REGISTER 360 much more quickly than raw scan data. Scan&Go is aware that time savings, workflow simplifications and productivity gains automatically translate into increased profits and accelerated paybacks.
