Hand System


The hand is probably the most complex human body part to acquire
in 3D. InSpeck’s Hand system is a specific configuration adapted
to digitize the particular physical attributes of a hand. This intricate
part of the human anatomy is best digitized by using multiple units
configured to work together as a Multi Head system.

A clear advantage provided by hese systems is that the acquisition
time is reduced from a few minutes (single) to as little a second
(Multi Head). The speed users get by combining multiple units
together allows them to digitize a hand even though it’s difficult
to keep a hand perfectly still. 


WHAT CONFIGURATION IS RIGHT FOR YOU? 

One of InSpeck’s digitizer’s great advantages is their configuration
flexibility due to its Multi Head systems. Users can either use 
them in single or multiple camera configurations.

SINGLE: One digitizer can effectively be used to capture one 
view of a hand. However, it quickly becomes difficult to get 
good results if a complete hand acquisition is needed, as the
subject cannot keep his/her hand completely still during the 
time it takes to capture the many views required.

MULTI: A multiple digitizer configuration consists of 2 or more 
3D Capturor digitizers linked together.  A single shot is 
needed to capture data and it is not necessary to have overlap
between cameras because of the calibration process that is 
done before digitizing. There is also no need for registration and
alignment due to previous calibration. 
Note: Calibration only needs to be done when configuration setup 
is changed.

Users will appreciate the time saved using Multi Head configurations 
and the scalable aspect of InSpeck’s systems. If the user has 
budget issues, InSpeck offers a modular approach consisting of 
purchasing one digitizer at a time and scaling up afterwards. 
Another benefit for users is that not only can they use their 
digitizers together but also individually depending on their projects.


SPECIFIC CONFIGURATION EXAMPLES

Two views:  Two digitizers is the ideal configuration to 
capture 85 to 90% (approx.) of the hand. It is the quickest and most 
affordable way to acquire the hand’s 3D geometry and texture. 
Thanks to the calibration target, the two views are already aligned 
together making the merging process a breeze. The EM software’s 
advanced mathematical algorithms will intelligently interpolate data 
that was not scanned following the natural shape of the hand
leaving a seamless surface geometry. 
Acquisition time: Less than one (1) second.

Three or more views:  When different hand positions are 
required, a configuration with more than 2 digitizers can be beneficial. 
Acquisition time: Varies depending on the number of systems used.

The digitizer type to be considered in the Hand system configuration is
[Small Field]. The [Small Field] has the advantage to give the highest
resolution of the hand. The digitized data of the hand can be used for
anthropometrics measurement, the design of custom gloves and the
creation of hand orthotics.
