从高度扫描激光扫描

Laser scanning has revolutionised the surveying profession in the recent years. With the possibility to capture large amounts of data in a relatively short time,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。

As processes digitise and businesses digitalise, surveyor firms around the world, like扫描和去，正在调整新技术，为客户提供更好，更快，更专业的服务。与Leica Geosystems合作，Scan＆Go是地形领域和3D高清调查领域的意大利公司领导者，对其车辆/三脚架安装进行了功能测试，用于使用该工具进行3D激光扫描Leica RTC360 3D激光扫描仪。

实现faster and more effective use of terrestrial laser scanners，扫描和GO创建可以安装在任何类型的车辆或气动杆上的系统，以便在扫描课程之间轻松移动并确保更大的测量范围。

Mounted on the Scan&Go System, the RTC360 captured at2 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。其余的三个扫描是在6-metre altitude from the ground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，”Scan＆Go销售经理Cristina Valchuk解释说。“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。”

The aim of the test was to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系统仪器安装在车辆上。扫描与GO团队也想测试correct functioning of the Visual Inertial System (VIS), performing the automatic point-cloud registration in the field, with speeds higher than those achieved by foot. The point cloud collected at a车速范围从10到20公里并实时注册使团队感到惊讶。

“The results obtained with the RTC360 are very good. During the scans, the system is very stable ensuring maximum measurement accuracy,”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.”

From raw data to smart data

点云只是空间中的一组数据点，直到利益相关者可以可视化和与之交互。从点云获得的3D模型有助于告知对现实的感知，并为操作提供了地理价值的数字基础。扫描和GO为客户创建3D模型，以便他们可以记录，管理，续订或维护任何资产或环境。在处理后处理之后旋风寄存器360，专家创建了Castelvetro Di Modena的3D模型。

Designed with simple and highly automated workflows in mind, theRTC360 solution uses edge computing to stream scan data to a tablet in real timeand automatically processes the scan data to provide实时质量控制and data registration in the field.

和自动预注册, high-quality point clouds were immediately available for the Scan&Go team. Quality assurance and completeness checks were also done in the field with the Cyclone FIELD 360 mobile application running on a tablet.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.
