VZAnalyzerTM works in conjunction with VZSoftTM
to provide motion measurement feedback for real-time or offline motion
control or data analysis applications. It imports the captured motion
data generated by VZSoftTM
into a graphical user environment in which the 3D motion measurements can be
processed by numerous scientific functions to extract higher-level motion
information. Applications of VZAnalyzerTM
include Gait Analysis, Neuroscience, Physical Medicine and Rehabilitation, Sports Medicine
and Performance, Structural and Vibration Analysis, Robotic Control, as well as reverse
engineering. Below introduces some of its functions. Please contact PTI for the complete
set of functions.
Compare Multiple Takes
Multiple takes of captured 3D motions can be compared in
VZAnalyzerTM. This can be used to analyze the
differences between the golf swing of a coach and that of a student,
or the before-treatment and after-treatment motions of a
rehabilitation patient, for example.
Rigid Body Function
"Rigid body" is also referred to as an "optimal-pose extrapolation
function". Through this function the VZAnalyzerTM can
compute the positions of occluded markers by making use of the
positions of visible markers which have been defined by you as
belonging to the same rigid-body as the occluded one(s).
Tracing and Graphing Motions
For better visual understanding of the captured motion, you can
graph or trace in 3D the motions of a marker, the center of an object
or a rigid body, or a line between two markers.
Define Virtual Markers
Virtual markers (also called 'Objects') can be defined to be anywhere
relative to groups of physical markers. These can be used to provide
position measurements of points that physical markers cannot be
directly attached to, such as the center of a limb or skull, or
a point outside the capture area.
Import Solid Objects
Solid Objects ('Polygons') made up by points can be imported into
the VZAnalyzerTM to create a scene for motion analysis.
These objects can be manipulated and/or driven by physical markers.
Thus they can be used, for example, to replicate the sports equipment
in a sports motion analysis application.
Create Video Clips
Motion displays within the VZAnalyzerTM can be
converted into a *.avi video clip and Saved with the take.
Conversely, a video recording can be imported into a take for
replaying in parallel with the motion capture data for comparison
