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 a precise as-built conditions that require a thorough building survey before design work commences. In the past, measurements were typically taken with a tape measure, paper and pencil. Fast forward to 3D laser scans, this provides a better way to quickly and accurately capture as-built conditions for building documentation.

3D laser scanning is a powerful technology that captures measurements with incredible precision and detail. When a 3D laser scanner is used, it sends out laser beams in a sweeping motion over the object or environment being scanned. These laser beams bounce back to the scanner, and the device calculates the distance traveled by each beam to create a detailed point cloud representation of the surface. By capturing millions of these points, the scanner is able to create a highly accurate and detailed 3D model of the scanned area. This technology is able to capture measurements quickly and efficiently, providing detailed information for various applications such as architecture, engineering, construction, and more. 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.

Coverting a point cloud into a Revit model, several steps must be followed. Initially, the point cloud data must be registered and stitched together. This data typically comes from HDR 3D laser scanning devices or similar technologies that contain millions of points representing the surfaces of the scanned object or space. Once imported, the point cloud can be used as a reference to create Revit elements such as walls, floors, ceilings, and other building components. By carefully aligning the Revit model with the point cloud data, precise measurements of the details can be captured to create an accurate representation of the scanned environment. The rich visual information from the point cloud helps in creating a detailed and realistic Revit model that can be further developed for design, analysis, and documentation purposes. The 3D scanners also capture’s remarkable photograph data that requires a combination of technical skill, artistic vision, and attention to detail.

Our desire is to provide detailed geometric data for architects, design professionals, engineers, and builders. Most of the buildings have already been built, but is poorly documented, that is where LNE Surveys comes in with 3D imaging. This provides the best foundation to start your projects, understanding what is existing and to help the professionals design the changes they want.

Three Dimensional Scan’s are essential, the swift capture of the 3D 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 the process. Similar to a camera, a laser scanner is a “line of sight” device: it sees what the viewer observes -it cannot see through objects. Dark, shiny surfaces do not scan as well as lighter, non-reflective materials.

Once the point cloud data is consolidated, traditional deliverables; 2d plans, elevations, and sections can be readily extracted, or used for fly-throughs and contextual purposes. While 3D modeling (BIM) is simplified using the point cloud data as the initial reference, the point cloud by itself can serve an architects main purpose, saving many hours of digital model building.

Additionally, 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 in most cases.
