测量点云...与GNSS Rover

我们测量点云。
This is the slogan from JTRS Registered Surveyor, a professional land surveying company in Singapore that provides 3D laser scanning, land survey, aerial mapping and inspection, photogrammetry and imaging services. JTRS is continuously looking for innovative and creative ways to improve the surveying services the company provides.
该公司的最新技术飞跃能够衡量地理位置的点云和积分与其全新技术获取 - 该Leica GS18 I GNSS RTK Rover。
“在单个仪器中使用实时定位捕获图像的能力，真正改变了我们进行测量的方式 - 它是现实捕获概念”bob综合app赌博jimmy tan，在jtrs上的所有者。
此外，随着倾斜补偿，它有助于获取RTK观察和录制，这在夜间工作时很有用，如我们必须在机场跑道或MRT高架桥工作。我不需要额外的双手握住枪光灯，在杆子升级时在泡沫中发光。“
除了测量点云之外，GS18 I具有强大的JTR，具有功能强大的RTK流动站，可在一个工具中结合快速的RTK初始化，倾斜补偿测量和视觉定位。使用GS18我添加到他们的投资组合，JTR已经能够提供新的服务并改善公司的当前服务。
防弹工作流程
JTRS主要使用GS18 I进行控制调查和施工项目中的调查和质量检查。紧凑的精度为50mm至100mm，在40mm内为大多数QC项目。对于每个项目，具有此多功能RTK GNSS Rover的工作流程是：
- Capturing the data using either the pole tip or Visual Positioning with the GS18 I and徕卡迷人现场软件
- 带Office软件的数据处理徕卡无限
- 创建带有：无限远的可交付成果（处理图像到点云），Leica Jetstream.（发布点云）和3D Reshaper.(to do mesh modelling based on point clouds).
在棕褐色的话语中，"With the GS18 I, I just need to point the camera onto the subject that I want to capture while walking. For example, in one of my projects, the time taken to survey the trial pit with the GS18 I was no more than five minutes. The time taken to post-process in the office using Infinity software was 30 minutes. I can produce true colourised point clouds, which I can export to orthophotos and also create digital surface models. It is also possible to create hundreds of topo points from the georeferenced images quickly and efficiently."
试用坑和竣工沟渠调查中的安全和速度
进行试井或竣工沟调查can be very challenging. Surveyors usually need to follow the site contractors' workflow and schedule as the trench needs to be backfilled, and the road lane needs to be re-opened as quickly as possible.
当JTRS有一个公用事业沟槽文档时，他们认为它是将新GNSS流动者陷入真正测试的机会。除了做出的试坑和地下实用程序的竣工调查外，GS18我允许它们创建3D点云并将其序列到3D网状模型中。
使用杆子尖端和视觉定位在现场测量和使用简单工作流程进行办公室的自由度，推动jtrs对另一个级别的测量边界。
质量控制检查调查中的信心和准确性
For a building and scanning project that included the 3D scanning of 1,200 blocks, JTRS carried the quality check of the georeferenced scanned data with the GS18 I. Once again, the tilt and Visual Positioning technologies on the sensor made it possible to access previously unreachable points.“在我们的HDB（住房开发委员会）的项目中，我能够使用视觉定位在我散步期间捕获的点坐标。通过GS18 I，调查方便，我可以获得即时结果离开网站。
当不可能使用极端尖端时，因为它太靠近建筑边缘并且RTK信号无法初始化，我们使用了视觉定位方法并远离有RTK信号的建筑物进一步走动。大多数情况下，如果网站条件使我们能够这样做，我们将使用这两种方法，“描述了棕褐色。
更平滑的工作流程+更高质量的交付成果=自信的客户
JTRS现在能够更安全并节省人力的成本，因为GNSS天线仅由一个人运营。要准备好使用GS18 I在现场上，该团队无需培训，只需要一个简短的介绍如何处理无穷大的图像。
"Clients are more confident in the quality of the deliverables. With Infinity, I am able to process the images into true point clouds with accurate georeferencing. With Visual Positioning, I can capture two images per second as I walk, and each image comes with global coordinates from a single source – the GS18 I. It is like flying the drone installed with a GNSS antenna and camera, except we are walking,"sustains Tan.

通过测量点云开辟新的机会
JTRS specialises in reality capture through 3D laser scanning and photogrammetry. The GS18 I adds to the company's motto of "measuring the point cloud" with an antenna that allows surveyors to capture sites freely and safely, carry QC for almost all its data and create multiple deliverables.
"We can further develop point clouds into a 3D mesh model – that's reality capture and it is very helpful in visualisation – many times better than a single point, single line or a 2D drawing. With Infinity you can also create Digital Surface Models. This is good for engineers or designers who can use this TIN model in their design work and easily extract heights and contours, water flows and more."谭说。
GS18我不仅有助于改进当前的服务JTR，而且帮助公司提供新服务。能够更快地创建多个可交付成果，并且资源较少导致更多的项目机会。

环境，社会和治理影响：工人安全
工人安全可以是特定测量任务的主要关注点。例如，在沟渠中或靠近沟渠（可能是危险的：风险包括落入沟槽，接触有毒烟雾，与埋地的服务线接触，由机械击中。任何需要更少人员和更少时间的技术有助于让工人安全。GS18我专为想要快速捕获环境的测量师而设计。他们可以在稍后决定在办公室中衡量并这样做的点，从而节省昂贵且可能有风险的现场时间。
