从磁带到点云

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激光距离仪表简化了工作。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。借助点对点测量技术，Groothedde可以从一个单个三脚架位置（例如旧建筑物）测量墙壁和天花板的一个三脚架位置中捕获3D的准确测量值，这并不总是彼此垂直。

The DISTO^TM当客户只需要一些维度时，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。With the BLK360, combined with an iPad Pro with Recap PRO mobile, an有效的工作流程可以制作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,”格罗省说。

Small device, big projects

Groothedde使用BLK360的第一个项目之一是荷兰蒂尔堡大学的建筑杰作。BLK360几乎没有直表面和弯曲的墙壁，立即证明了其强度。

BLK360还被公司使用来捕获零售建筑的现实。老城中心的商店的布局复杂，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亚博ag真人规律一个或两个小时。

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 thelightweight, 1-kilogram事实证明，BLK360足够大了。

“由于尺寸很小和激光扫描仪的60米范围，因此有可能进入最小的空间。由于扫描仪的尺寸较小，也进行了排水沟的几次扫描。另一方面，可以从地面测量立面，透明格罗省说。

Looking ahead

有一个散开^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提供卓越的价值。在c语言中ombination 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,”格罗省说。

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