从磁带到点云

要衡量。

该短语是我们如何获取知识和改进任何方法的基础。最终，这句话也被具有尺寸相关职业的人使用，例如荷兰工程公司Groothedde的所有者Pascal Groothedde。

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.

从点对点到数百万分

过去，当需要尺寸时，使用尺寸胶带。磁带量后来被激光距离计替换。由于Groothedde经常独自工作，所以一个左撇子^TMS910 laser distance metre eased the job. As projects gained complexity, the DISTO^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。

散落^TMS910 is still used when a customer only needs a few dimensions, but recently, Groothedde invested in the Leica BLK360 imaging laser scanner, opening new opportunities for his company.

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efficient workflow可以制作2D平面图，横截面和3D型号。

“捕获每个项目的正确信息始终是一个挑战。您想在现场进行尽可能多的测量，以确保到达办公室时拥有所需的一切，但只能在设备的可能性内工作。以前，这些项目是通过传统散布来衡量的^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。

小型设备，大项目

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.

The BLK360 is also used by the company to capture the reality of retail buildings. Shops in old city centres have a complex layout and are often built with no straight walls and straight lines in the interior. Using the BLK360, Groothedde was not only more efficient capturing a set of stores in the centre of Nijverdal, Netherlands, but also caused less disturbances to the businesses. The captured point clouds generated 2D floor plans for the contractor. Where a project in the past used to cost a day, now reality capture is done inone or two hours。

3D成像激光扫描仪也使您可以从外部扫描4750-cubic-metres建筑物将在豪华公寓中进行改建。所有者需要规划的尺寸，以及轻量级，1公斤BLK360 proved to be big enough for this task.

“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,”格罗佩德说。

Looking ahead

有散开^TMS910和BLK360，Groothedde涵盖了他的大部分建筑建设和零售项目需求。可以更快地完成项目，并且可以轻松地使用点云数据来制作2D平面图，横截面和完整的3D模型，例如AutoCAD或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.
