Larger values will result in greater search areas,
which will take a longer time to search. Typically this
parameter is set two to three times the size of the initial
image template (defined in pixels). When initiated, the
software will automatically find and track the template
region as it progresses through each frame.
Manual Tracking requires the analyst to select every point
being tracked for each frame. With either method all
tracked points are logged to a measurement file that can
be used to generate a coordinate, speed, or acceleration
spreadsheet easing report generation.
Data Acquisition
To investigate the effect environmental conditions may
have on the recorded data, a National Instruments
™
USB- or M- Series Data Acquisition (DAQ) module
can also be used to acquire data from a wide range
of sensors, and synchronize it with slow-motion video
images recorded on a Phantom camera, using Phantom
Camera Control (PCC) software.
