The new FastSCAN
CobraTM 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.

| FastSCAN
Cobra is designed to scan non-metallic, opaque objects.
The scanner works by casting a fan of laser light over the
object, while the camera on the wand views the laser to record
a cross-sectional profile of the object. The embedded FASTRAK
is used to determine the position and orientation of the wand,
enabling the computer to reconstruct the full three-dimensional
surface of the object. Moveable objects may be scanned by
attaching a second receiver to the object.

New Stylus Marker Functionality
Option
Once initialized, pressing the stylus button generates a position
and orientation marker within the tracker's spatial system.
These coordinates are recorded by the FastSCAN Cobra software
and displayed on the screen. Digital reference markers provide
an indication of the exact position and orientation of the
marked point. The digital reference can then be exported.

| Two exports of the
same surface at different export smoothing parameters. The
Export Smoothing parameter controls how much smoothing FastSCAN
Cobra uses when merging sweeps. A low value creates a more
detailed surface, but will fail to merge more widely separated
sweeps. A higher value will merge sweeps better, but will
remove more surface details. |

Scanning
People
The handheld laser scanner can
be used to digitize a human shape for animation,
multimedia, custom apparel design, biomedical research,
forensics, etc. The following example demonstrates
the scanner's ability to:
|
·Scan
a human subject rapidly while subject remains still
·Use the second receiver
on a headband to track involuntary movement of the subject
·Scan a complicated surface
with convolutions that would normally be obscured from
a conventional
turntable-based laser scanner
|
|
| Scanning
Objects The handheld laser scanner can be
used to digitize the surface of objects for animation,
rapid prototyping, 3D measurement, archiving, etc.
The following example demonstrates the scanner's ability
to: |
·Rapidly
digitize the complete 3D surface of an object
·Save
the data in industry standard formats to be used by
other programs |
