What is
Laser scanning constitutes the deflection of laser beams.
3D Scanning involves the process of analyzing real-world object for collecting data of shapes and appearance. The collected data is then used for constructing digital 3D Models, consisting of a polygon mesh or point cloud of geometric samples on the surface of the object. These points are then used to extrapolate the shape of the subject called reconstruction. The volumetric technique helps multi-sampling and data compression.
Laser Scanning?
Scanned laser beams are used in: 3D printers Rapid prototyping Material processing Laser engraving machines Ophthalmological treatment of presbyopia Confocal microscopy Laser printers Laser shows Laser TV Barcode scanners
Purpose of Using Laser Scanning Technology Manage, synchronize & supervise data Obtain verified & reliable data in real time Plan ahead & optimize building performance Maintain project progress as per construction schedule
Benefits of Scan to BIM Technology Accuracy - Accurate 3D Model Creation for renovation & extension, allowing reliability & quality assurance Efficiency - Improved platform for preparing detailed design work Reducing Rework - Elimination of work stoppage & rework, saving project time & money
Technology Used for Laser Scanning Scanning mirrors: Moveable light-weight mirrors for steering laser beam, with reflectivity of 99.5%, mounted on galvanometer Scanning refractive optics: A laser beam gets scanned when optical lenses are moved or rotated against each other Material effects: Used by special laser scanners to enable highest scanning frequencies Phased array scanning Utilized for scanning radar beams without moving parts
