From tape to point cloud

Author:Arno Kijzerwaard

To measure is to know。

This phrase is the basis on how we acquire knowledge and improve any method. This phrase, eventually, is also used by people with dimensioning-related professions, such Pascal Groothedde, owner of the engineering company Groothedde in the Netherlands.

Groothedde专门研究建设，项目管理，建筑检查和预算。公司从事的项目通常从事零售业务（商店构建）或与建筑建设有关的项目。bob综合app赌博现实捕获已经花了Groothedde来扩展其业务组合，与传统方法相比，提供3D模型和CAD图纸。

From point-to-point, to millions of points

In the past, when dimensions were needed, the measuring tape was used. The tape measure was later replaced by a laser distance metre. Since Groothedde works often by himself, a Leica DISTO^TM值S910激光距离米缓解了工作。作为projects gained complexity, the DISTO^TM值with 3D measurement technology proved to be the right tool. With point-to-point measurement technology, Groothedde could capture accurate measurements in 3D from one single tripod position in, for example, old buildings, measuring the walls and ceilings, which not always are perpendicular to one another.

The DISTO^TM值当客户只需要一些尺寸时，仍然使用S910，但是最近，Groothedde投资于Leica BLK360成像激光扫描仪，为他的公司开辟了新的机会。

Using the 3D imaging laser scanning, Groothedde discovered a快速且简单的方法来捕获测量和产生的信息。With the BLK360, combined with an iPad Pro with Recap PRO mobile, an有效的工作流程is in place to make 2D floorplans, cross sections and 3D models.

“It is always a challenge to capture the right information for each project. You want to measure as much as possible on site to make sure you have everything you need when you arrive at the office, but you can only work within the possibilities of the equipment you have. Previously, the projects were measured with a traditional DISTO^TM值。

由于目前在3D激光扫描中的发展以及BLK360的发布，我们决定投资于成像激光扫描仪。由于BLK360的测量每秒高达360,000点，因此我们不必担心是否在现场测量了足够的积分。我现在可以比以往任何时候都接受不同，更复杂的项目，并且更好地满足了客户的需求。”said Groothedde.

Small device, big projects

One of the first projects where Groothedde used the BLK360 was an architectural masterpiece of the Tilburg University in the Netherlands. With almost no straight surfaces and curved walls, the BLK360 proved immediately its strength.

BLK360还被公司使用来捕获零售建筑的现实。老城区中心的商店有一个复杂的布局，通常在内部没有直墙和直线。使用BLK360，Groothedde不仅在荷兰Nijverdal中心捕获了一套商店，而且对企业造成了较少的干扰。捕获的点云为承包商生成了2层计划。过去一个项目过去每天花费的项目，现在已经完成了现实捕获bob综合app赌博一两个小时。

The 3D imaging laser scanner also made it possible to scan from the outside a4750立方米building to be remodelled in a luxurious apartment. The owner needed dimensions for the planning, and thelightweight, 1-kilogram事实证明，BLK360足够大了。

“由于小尺寸和60-metre响了e of the laser scanner, it was possible to get in the smallest spaces. Even a few scans from the gutter, at 31 metres above ground level, were made due the small size of the scanner. On the other hand, it was possible to measure the façade from ground level,透明said Groothedde.

展望未来

With a DISTO^TM值S910 and the BLK360, Groothedde covers most of his building construction and retail project needs. Projects can be done faster, and the point cloud data can easily be used to make 2D floorplans, cross sections and complete 3D models in, for example, AutoCAD or Revit.

“The BLK360 offers excellent value for money. In combination with the iPad Pro, it gives immediate feedback in the field – with the tablet you can instantly see what you captured, what you need, and if the scans have enough overlap,”said Groothedde.

在未来，Groothedde希望通过提供更高的精度和云共享详细的点云来发展其3D测量业务。
