From tape to point cloud

要衡量。

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 specialises in construction, project management, architectural inspections and budgeting. The projects the company undertakes are often in the retail business (shop-fitting) or related to building construction. Reality capture has taken Groothedde to expand his business portfolio, delivering 3D models and CAD drawings much faster and detailed than with traditional methods.

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^TMS910激光距离表减轻了工作。随着项目的复杂性，散布^TM用3D测量技术被证明是正确的工具。通过点对点测量技术，Groothedde可以从一个单个三脚架位置，例如旧建筑物，测量墙壁和天花板，在3D中捕获3D的准确测量，这些位置并非总是彼此垂直的。

The DISTO^TM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。

使用3D成像激光扫描，Groothedde发现了一个fast and uncomplicated way to capture measurements and as-built information。与Blk360一起，与iPad Pro一起使用Recap Pro Mobile，一个有效的工作流程is in place to make 2D floorplans, cross sections and 3D models.

“这一直是一个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。

Due to the current developments in 3D laser scanning, and the release of the BLK360, we decided to invest in the imaging laser scanner. Since the BLK360 measures up to 360,000 points per second, we don’t have to worry if we have enough points measured on site. I can now take on different and more complex projects than ever before and better meet the needs of my customers,”格罗佩德说。

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-cubic-metresbuilding to be remodelled in a luxurious apartment. The owner needed dimensions for the planning, and the轻量级，1公斤事实证明，BLK360足够大了。

“Due to the small dimensions and the 60-metre range 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,透明格罗佩德说。

Looking ahead

With a DISTO^TMS910 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.

“ BLK360物有所值。结合iPad Pro，它可以立即在现场提供反馈 - 使用平板电脑，您可以立即看到您捕获的内容，需要的内容以及扫描是否足够重叠，”格罗佩德说。

For the future, Groothedde wants to grow his 3D measurement business by delivering higher accuracy and cloud sharing detailed point clouds.
