Laser scanning from heights

近年来，Laser扫描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激光扫描仪是收集数据的必备仪器，以产生从简单的地形调查到3D模型的输出，以保留文化遗​​产。

随着流程数字化和企业数字化数字化，世界各地的测量师公司都像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.

安装在扫描和GO系统上，RTC360捕获在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距地面6米使用扫描和GO车辆安装。

“扫描仪的高度允许克服存在的障碍物，并增加扫描范围及其测量准确性，”explained Cristina Valchuk, sales manager at Scan&Go.“所有扫描都是完美平整的 - 这消除了垂直变化。我们对测试的满意度很高。这种方法可确保操作员的安全性和仪器在现场的安全性，并提高RTC360的生产率。”

测试的目的是验证新的RTC360的潜力，并结合用于移动“停止”和“ GO”模式的激光扫描的扫描和GO系统with the instrumentation installed on the vehicle. The Scan&Go team also wanted to test the视觉惯性系统的正确功能（VIS），在现场执行自动点云的注册，其速度高于步行的速度。点云收集在车速范围从10到20公里并实时注册使团队感到惊讶。

“使用RTC360获得的结果非常好。在扫描过程中，系统非常稳定，可确保最大的测量精度。”瓦尔丘克说。“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，RTC360解决方案使用边缘computing to stream scan data to a tablet in real time并自动处理扫描数据以提供实时质量控制和该领域的数据注册。

和自动预注册，扫描与GO团队立即可立即使用高质量的点云。质量保证和完整性检查也在现场进行，使用平板电脑上的Cyclone Field 360移动应用程序。这降低了现场数据捕获过程的复杂性，并在现场和办公室中节省了团队成员的时间由于他们能够离开项目站点的预注册，可以在Cyclone寄存器中最终确定比原始扫描数据更快。Scan＆Go知道，节省时间，工作流程简化和生产力的提高会自动转化为增加的利润和加速投资回报。
