Laser Scanning or 3d object scanning as it is
sometimes known is a quick way of getting objects from the real world
into a computer for a variety of uses.
3d Laser scanning lends itself particularly well to several
fields including the Film and Television Industries, Sculpting, Modelmaking, Jewellery making, Marketing and Media
projects, Web Visualisation, Rapid prototyping (RP) and Reverse
engineering.
The procces is actually called laser stripe scanning because of the methods
used to capture the object geometry. A laser light is split into a fine line
and shone at the obect revealing a stripe that a camera then captures and
turns into digital data. This happens at a rate of between 25 to 30 stripes
per second.
The data is then collated into a replica of the subject. Colour information is captured
at the same time and complex objects are scanned from several different angles
of multiple scans to build the entire object.
