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). The collected data can then be used to construct digital 3D models. A 3D scanner can be based
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.
Compared to 3D laser scanning, structured-light scanners can offer advantages in speed and safety by using non-coherent light sources like LEDs or projectors instead of lasers. This approach allows for relatively quick data capture over large areas and reduces potential safety concerns associated with laser use.
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]
The most notable are the laser range-finding system created in 1992 for the DANTE walking robot that explored Mount Erebus in Antarctica as part of a NASA sponsored competition [18] and the 360-degree phase-based 3D laser scanner named SceneModeler created in 1997.
Laser Design Inc. is a company headquartered in Minneapolis, MN that designs, manufactures, and sells 3D laser scanners used to digitally capture the shape of physical objects such as free-form surfaces and geometries.
