3d Laser scanning
Accurate measurements have always been a crucial element in the design process, from initial design studies through final construction documents. This is especially true for as-built surveys that require a detailed survey before design work commences. In the past, measurements were typically established using the total station.
Now 3D laser scanning provides a better way to quickly and accurately capture as-built conditions for building documentation. 3D laser scanning captures as-built conditions rapidly and precisely. Once assembled, the scanned images reveal building relationships in ways difficult to imagine, let alone measure. ADB3D provides detailed spatial information to architects, design professionals, engineers, and builders.
Laser scanning is essentially the precise capture of three-dimensional information reflected from an object or surface to a light sensor. It creates a 3D construct called a “point cloud” made from multiple scans that have been unified through a process of “registration”
Once the point cloud data is consolidated, traditional deliverables, 2d plans, elevations, and sections can be readily extracted. BIM models, fly-throughs and point clouds are used for contextual purposes.
Precise measurements can be taken between individual scan points, edges, and planes. Laser scanning reveals deformation from poor construction or the cumulative effects of time. After the scans are registered, a three-dimensional database is established that can be used throughout the building’s lifecycle, or to aid in reconstruction should damage occur in the future.
remarkably sharp and descriptive photographic data is fused with the point cloud and can be easily viewed as dynamic panoramas. These images are dimensional and can be annotated and modeled to suit your project.
