uses a Cyberware 3030RGB laser scanner
mounted on a PS rotating platform for the capturing of three-dimensional
form data of objects. During digitizing of an object, a safe,
low-intensity (grade 1) laser is projected onto the object to
create a highlighted profile. A high-quality video sensor captures
this profile from two viewpoints. The system digitizes hundreds
of these profiles in a few seconds to capture a three-dimensional
(3D) replica of the object in space. Simultaneously, a second
video sensor captures colour information of the object. The
addition of colour information to 3D digitizing provides nearly
all the information a graphics application requires to fully
describe an object. In addition to enhancing realism in graphic
models, colour denotes boundaries that are not obvious from
shape alone. The digitized and colour data are transferred to
a graphics workstation for immediate viewing and modification.
An object (of a maximum size of W 300 mm x H 300 mm) can be
digitized and displayed on the graphics workstation in less
than half a minute. Digitized objects will have a spacial resolution
of between 0,1 mm and 2 mm depending on object size, and can
be exported in 3D studio, ASCII, dxf, iges (106, 124, 128),
inventor, obj, ply, scr, stl and vrml file formats to be imported
directly into a number of CAD or computer animation packages.
