laser scanners. Both affordable and easy to use, the PS-Series scanners enable users to quickly scan complex
textures and geometric data from any object. The USB-interfaced system creates a 3D digital model, which can be
easily manipulated with optional scan processing software from Raindrop Geomagic. The Geomagic software
performs editing and model-building functions including scaling, smoothing, point cloud editing, STL model generation,
surface modeling, and stitching together of the data from multiple scan orientations to efficiently and accurately create
3D digital models. These models are then easily imported into popular CAD/CAM and 3D graphic software programs.
The PS-Series scanners use Laser Triangulation, an active stereoscopic technique where the distance of the object is
computed by means of a directional light source and a video camera. A laser beam is deflected from a mirror onto a
scanning object. The object scatters the light, which is then collected by a video camera located at a known
triangulation distance from the laser. Using trigonometry, the 3D spacial (X-Y-Z) coordinates of a surface point are
calculated. The CCD camera's 2D array captures the surface profile's image and digitizes all data points along the
laser. Generating more than 100,000 polygons in a single scan, the PS-
