Measure What You See — How New GNSS Technology is Helping Surveyors Improve Efficiency

作者：安妮·皮特卡宁（Anne Pitkaenen）

Many variables can complicate a surveyor’s job. Measuring a point where the view to the sky is limited can be difficult. Surveyors often face a race against time to survey a site before the first foundations are laid.

提高效率通常是迈向更有利可图的业务的第一步。无论您在现场面临什么挑战，依靠快速准确的测量设备都可以轻松克服障碍。

Capturing hard-to-access or obstructed points

难以访问的点是测量师工作的一部分，就像硬帽子和高VIS服装一样。解决它们通常需要其他设备，这会使事情变得复杂并减慢您的速度。

You might, for example, need to map a point of interest on the other side of a busy road. Crossing roads safely is difficult, and blocking the traffic consumes time at the site. Another common challenge is obstructed points. Take, for instance a point under an overhanging canopy. Without a view to the open sky, measuring with a traditional GNSS rover will be a challenge.

In most cases, and with most conventional RTK rovers, you have little choice but to measure the point using additional equipment such as a total station or a DISTO™.

There’s nothing wrong with this approach. It works. But the additional equipment needed means more to transport between sites, longer set-up and processing times and extra costs — all of which slows you down.

With its integrated camera, the newLeica GS18I makes this process far simpler. When faced with a hard-to-reach point, like our canopy example, there’s no need to try and reach it with other means. The GS18 I allows you to walk alongside the structure capturing images as you go. These images are used to measure survey-grade points, which can be further processed into a point cloud. Also, the GS18 I automatically defines the position and orientation of the images, making them ready to use for measuring instantly in the field.

在几分钟内测量数百分

准确地绘制数百个点，无论是建筑物的整个立面还是在沟渠中穿过的几根管道，都可以耗时。如果您使用的工具可以逐点测量结构，则尤其如此，就像某些常规的RTK流浪者一样。

The GS18 I is capable of capturing the site in images as you walk. These images can be used in the field or office for measuring points in them. This means even vast structures, which would typically have taken hours to measure can be captured much more quickly and efficiently. Also, you never miss measuring a point.

您无需返回站点即可测量其他点，因为即使出现新的点需求，也可以从图像中测量它们。

In the office, points can be measured with Leica Infinity office software conveniently on a larger screen. Office time is, in general, less expensive than time on site — there are no disturbances and frustrations from weather and fewer risks.

在网站上查看数据

Some imaging GNSS systems don’t allow you to review what you are doing on site. Those systems that use a GNSS together with a camera but don’t have Visual Positioning technology, like in the GS18 I, often require processing back at the office before it can be used for measuring. This means waiting to return to base to check whether you’ve captured everything correctly.

This just isn’t practical. If you’re visiting multiple sites in a day, you need to be able to review and upload work on the go and ensure you have everything you need before continuing to the next job. Anything else risks multiple site visits to correct errors, having a negative impact on your productivity.

GS18我更有效地处理了这一点。当您使用GS18 I的视觉定位时，它会自动定义图像的位置和方向，从而准备好用于测量。另外，无需在多个图像上选择一个点 - GS18我会自动匹配该点。您需要做的就是选择点并点击度量以立即计算坐标。

This means no waiting until you’re back at base to check whether you have mapped everything you need and the quality matches the project requirements. With the GS18 I, everything is available instantly. So, you can access the quality of the results on-site and leave the rest of the measuring for the large screens back at the office.

可以在现场审查积分，从而减少了错误的风险。您无需返回站点即可纠正错误或在等待返回办公室时延迟项目。

GNSS赋予您的业务能力

Surveyors will probably always face complications in their projects, but the right technology certainly makes things easier. Visual Positioning technology is providing access to many points that were previously unreachable with a conventional GNSS rover alone. And, with the GS18 I, surveyors now have a simpler, faster more efficient tool for handling whatever they encounter on site.

Tackling inefficiency in your surveying business starts with your equipment. And the GS18 I provides an answer to many of the common problems that cause it. Get everything you need to start transforming your business in a single, easy-to-use device.

什么是Leica GS18 i？

Leica GS18 I是最通用的测量级GNSS RTK ROVER，使您可以测量与图像的遥控点或用极尖端测量的遥控点。它具有与GS18 T相同的功能，但具有添加的视觉定位技术。视觉定位技术，将GNSS，IMU和相机组合的传感器融合，使用户可以安全有效地达到以前无法访问或阻塞点。
