3D BIM Laser Scanning Vs. Photogrammetry – Choose the Right Technology for Construction Today, it’s difficult to envisage the world without digital technology. Nevertheless, the physical world is getting designed & constructed using conventional 2D blueprints, which is yet to be seized in a digital setup. This creates a challenge for the AEC (Architectural, Engineering & Construction) professionals to integrate the as-built designs into renovation projects. Conventional Imaging Technique – Photogrammetry: Conventional imaging techniques like Photogrammetry facilitated this process by letting engineers reconstruct photographs of as-built situations and weave in GPS (Global Positioning System) coordinates for creating collaborative 3D models. Photogrammetry indeed allows you to encompass a considerable amount of ground, but it does with low accuracy. 3D Laser Scanning for Building Renovation & Retrofitting: 3D laser scanning consists of a smaller footprint of data, collected to a higher level of accuracy. Laser scanners collect surface data through a laser beam pointed at the surface. The technology often uses drones or UAVs (eradicating expensive LiDAR assembly methods) and transforms that data into a point cloud. Then the point cloud data gets imported into tools like Autodesk ReCap, transforming it into a 3D model or 2D drawing equipped for additional design in just a matter of minutes. Besides laser scanning, Autodesk Recap converts aerial as well as to object photographs of 3D models. Why should you consider 3D Laser Scanning to BIM Technology?
