Making a 3D-model of a Viking belt buckle using a hand held VIUscan 3D laser scanner. 3D scanning is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color).
Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in which case it is known as lidar scanning or 3D laser scanning, a special combination of 3-D scanning and laser scanning. [3] Lidar has terrestrial, airborne, and mobile applications. [4] [5]
Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
3D laser scanners for accurate 3D measurement; Laser line levels are used in surveying and construction. Lasers are also used for guidance for aircraft. Extensively in both consumer and industrial imaging equipment.
The laser scanner is the main component of LiDAR. Lasers with a wavelength of 550-600 nm are used on a ground-based system (handheld laser scanning and terrestrial laser scanning), whereas airborne systems use lasers with 1000-1600 nm wavelength. [19] Laser calculates the reachable range by the following formula: [19]
DAVID Laserscanner is a software package for low-cost 3D laser scanning. It allows scanning and digitizing of three-dimensional objects using a camera (e.g. a web cam), a hand-held line laser (i.e. one that projects a line, not just a point), and two plain boards in the background. The software generates 3D data in real time and shows them on ...
