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 ...
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).
Recently, there has been an effort in the computer vision community to handle such optically complex scenes by re-designing the illumination patterns. [6] These methods have shown promising 3D scanning results for traditionally difficult objects, such as highly specular metal concavities and translucent wax candles. [7]
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.
The model describes the process of forming the shape of an object. The two most common sources of 3D models are those that an artist or engineer originates on the computer with some kind of 3D modeling tool, and models scanned into a computer from real-world objects (Polygonal Modeling, Patch Modeling and NURBS Modeling are some popular tools ...
In computer vision, 3D object recognition involves recognizing and determining 3D information, such as the pose, volume, or shape, of user-chosen 3D objects in a photograph or range scan. Typically, an example of the object to be recognized is presented to a vision system in a controlled environment, and then for an arbitrary input such as a ...
Once the objects are given, either by modeling (computer-aided design), by scanning or by extracting shape from 2D or 3D images, they have to be simplified before a comparison can be achieved. The simplified representation is often called a shape descriptor (or fingerprint, signature).
Simplygon is 3D computer graphics software for ... 3D CAD, 3D scan, ... An aggregation process combines all geometry and materials in a scene into one single object.
