3D Optical Digitizers
Patterned light is projected onto subjects; deformation is recorded by an off-set camera. Triangulation calculates a 3D mesh. Fast, accurate and adaptable for human portraiture.
3D Laser Scanners
A laser line moves over subjects' surfaces; an off-set camera records deformation. Triangulation calculates a 3D mesh. Slower, but higher accuracy enabled for static objects.
3D Mechanical Digitizers
Mechanical arms physically probe objects, guided by the user; points are recorded on the surface of subjects. Intuitive but slow. Unsuitable for delicate objects.
3D Scanning software
View, edit and export scan data efficiently and accurately. Triangulation, registration and merging algorithms, polygon editing, CAD conversion, model export for web viewing.

Polhemus FastScan Cobra/Scorpion - Handheld
3D Laser Scanners
The new FastSCAN Cobra™ is 30% less expensive
and 50% smaller than ever, while retaining all functional capability, allowing
continued ease of use and greater portability. FastSCAN Cobra instantly acquires
three dimensional surfaces by gathering measurements made by smoothly sweeping
a handheld laser scanning wand over an object - in a manner similar to spray
painting. The object's image instantly appears on your computer screen and the
finished scan is processed to combine any overlapping sweeps, significantly
reducing the time to develop surface models of virtually any object with little
or no metal content. The three-dimensional data can then be saved in industry-standard
formats for loading into other programs.
Polhemus FastScan Cobra
As the industry's most portable and lightweight
handheld scanner, FastSCAN Cobra allows you to go where no scanner has gone
before - on archaeological digs, directly to the plant floor, and in to sensitive
areas such as medical examination rooms. Significantly speeding up the modelling
process, FastSCAN Cobra instantly stitches together an exact replica of the
object while it is being scanned. Measurements are made by smoothly sweeping
the FastSCAN Cobra Wand over the object - in a manner similar to spray painting.
Just like magic, an image of the object appears on your computer screen and
the finished scan is processed to combine overlapping sweeps. Exports to Industry
Standard Graphics Applications This three-dimensional data can then be saved
in industry-standard formats for loading into a host of popular 3D modelling,
graphics and CAD programs.
FastSCAN Cobra works by projecting a fan of
laser light on the object while cameras on the Wand view the laser from either
side to record the 3D surfaces of the object. Its magic comes from incorporating
Polhemus patented FASTRAK® motion tracking technology in the wand itself.
The magnetic tracker is used to determine the position and orientation of the
Wand, enabling the computer to reconstruct the full three-dimensional surface
of the object. You can also scan objects that are prone to movement - head and
hands, for example. Just attach a second Tracker Receiver to the object. Since
FastSCAN Cobra uses electromagnetic technology to create its magic, you'll find
it ideal for scanning non-conducting, opaque objects. For the ultimate in 3D
scanning, experience the revolutionary FastSCAN Cobra Handheld 3D Laser Scanner
for yourself.

FastRBF Extension
With new FastRBF extensions, FastSCAN now represents
a complete rapid prototyping solution in a single package.
The automatic hole-filling and smooth extrapolation
of incomplete surface data that the FastRBF extensions provide saves many hours
otherwise spent laboriously repairing holes and defects in scans. All this is
done without compromising the high detail of the original scan. FastRBF, however,
also offers advanced smoothing and noise rejection techniques along with sophisticated
mesh simplification that exploits the unique mathematical function that FastRBF
uses to model the scan data. Consequently, surfaces simplified with FastRBF
are more faithful to the raw scan data than other traditional methods. The FastRBF
plug-in also guarantees that a water tight, manifold surface is exported from
the scanner - an essential consideration for rapid prototyping and a unique
capability in a laser scanner. With the FastRBF extensions, all this capability
is now available to the user at the time of acquisition.
FastRBF surface extrapolation and mesh simplification
This example demonstrates FastRBF hole
filling, surface extrapolation and mesh simplification in order to create
a water tight model suitable for manufacture by rapid prototyping. The complete
task is solved within the scanner software at the time of acquisition. FastRBF
is used to create a smooth water tight surface from the raw laser scan data
of the bust scanned above. Holes are automatically filled and the surface
smoothly extrapolated to a user-defined bounding box, the very fine mesh derived
from the Radial Basis Function (left) was then simplified prior to exporting,
while still maintaining the high detail of the original scan (right).
The FastRBF extensions offer key scanning improvements:
Automatic hole filling
Smooth extrapolation
of surfaces
Mesh simplification
while preserving scan detail
The export of guaranteed
closed water tight meshes
Meshes characterized
by more uniform triangles
Low pass filtering
(smoothing) of scans
Error-bar fitting
for noisy data - just specify a fitting tolerance
FastScan Scorpion
The Scorpion uses the same technology as the Cobra, casting
a fan of laser light over the object, to produce a scan. The Scorpion has two
cameras allowing for more detailed scans. While scanning an object the cameras
on the wand view the laser from either side to record cross-sectional profiles
of the object.
