How Reality Capture is Improving Accuracy in the Design & Construction Industry

December 11, 2018

Scan with Accuracy, Design with Confidence

Having a comprehensive scan of the entire site can help you detect issues earlier than traditional surveying methods and often give an “under the hood” or “up close” insight into potential problems you may run into. Issues that can cause serious rework or halts in a project’s timeline include:

●  Structural issues like bowing, buckling, or deflection.

●  Thermal changes to the site or structure from freezing or thawing during seasonal changes.

●  Effects of façade treatment on environmental quality of a building’s interior.

●  Incorrect installation of mechanical, electrical, plumbing and other complex building systems.

●  Geotechnical or topographic issues.

●  Inaccurate mapping of utility placements or other hidden site elements.

●  Inability to measure earthwork and site changes over time.

Accuracy is Everything

With all these potential issues that could arise, accuracy in reality capture is extremely important. With reality capture technology today, we’ve eliminated the need for out-of-date 2D blueprints or fussing with tape and distance meters at site visits to validate existing conditions. We’ve also removed the need for more return trips to double or triple check measurements. With photo-to-point cloud creation or laser scanning, you can gather millions of points simply by taking photos with a camera-equipped unmanned aerial vehicle (UAV), hand-held device, or laser scanning device. You can combine this captured data from both sources, if needed. Reported accuracy for most terrestrial laser scanners currently in market is 3 mm.7 With the ability to take such exact measurements, your projects and sites, large or small, can be captured with an amazing level of detail.

This scanned data is actionable combined with a digitized 3D model in the software of your choice. Each point captured is mapped onto an XYZ coordinate system, providing a more intelligent survey output to export for use.

Rework is eliminated, because scanning technology uses information from hundreds of photos or scanned points within seconds of capture time. You can accurately pinpoint buried or hidden infrastructure if it’s captured during installation, preventing unnecessary revisions later.

You won’t have to go back to the site to remeasure and double check the initial survey measurements. Just place your laser scanner on a tripod or set a UAV with LiDAR scanner on a defined flight pattern. The technology takes over from there to create a superior 3D model with millions of scanned data points and laser accuracy from the first site visit.

You can measure the model, view and analyze data in elevation maps, organize
and clean up regions within the point cloud, create a mesh, and manipulate the model.
