In Defense of Traditional 3D Laser Scanning


With rapid developments in 3D scanning technology over the past thirty years, reality capture is now faster and easier than ever, taking form in high definition terrestrial systems, aerial photogrammetry systems, handheld infrared systems, and everything in between. In this article, Tucker Cedarleaf of Cedar+Mac, who has been working with laser scanning equipment and software for over 10 years, debunks the assumptions many users make that all reality capture is equal and that it’s as simple as taking photographs. He shows how and why traditional laser scanning tied to survey control is the only method of 3D capture that produces baseline data of the quality and reliability required for AEC industry use.
