into some Vicon application software.
Also see Marker and Trajectory.
Trial The result of data capture in a
Vicon system. The two basic types of data
capture are dynamic trials and static
trials. Trial data can be saved to file types
appropriate for the stage of processing.
Also see .c3d file, Dynamic trial, Static
trial, .trial file, .tvd file, and .x2d file.
.trial file A binary file with extension
.trial, which contains all data from a
motion capture trial (e.g. unprocessed 2D
camera, rigid body, virtual point, and
kinematic data). This file can be created
when the real-time stream is acquired by
Vicon motion capture systems and when
offline data is processed in some Vicon
application software. By default, .trial
files are saved to the active Session
folder of the open database. Also see
Data capture, Kinematic model, Motion
capture, Rigid body, Trial, and Virtual
point.
.TrialType file An XML file with
extension .TrialType, which contains
configuration settings for motion capture
trial setups created in the Capture tool
pane in Vicon Nexus. Also see Nexus.
Trigger A specified event that initiates
or terminates remote data capture or
synchronization in a Vicon system. This
can be when a specific level either in
increasing or decreasing signal is reached
or at a specified point of an incoming
analog signal. Also see Post-Triggering,
Remote triggering, and Timecode
triggering.
Truck The moving of a camera side to
side along a horizontal axis (truck left or
truck right). Also see Dolly, Pan, and Tilt.
.tvd file A binary file with extension
.tvd, which contains 2D camera data
previously captured in a Vicon V-series
system. By default, .tvd files are saved to
the active Session folder of the open
database. Also see Eclipse database and
Vicon V-series system.
V
.vad file Vicon Analog Data file. A
binary file with extension .vad, which
contains unprocessed data from analog
data capture. By default, .vad files are
saved to the active Session folder of the
open database. Similar functionality is
provided by the .x1d file in Vicon Nexus.
Also see Analog and Nexus.
VCam A small format, wide-angle lens
CMOS digital sensor camera used in a
Vicon V-series system. This type of
camera is the same specification as an
SV Cam camera with a standard body
and strobe size. Also see CMOS, SV Cam,
and Vicon V-series system.
Vector A quantity that has both
direction and magnitude. For example,
velocity is a vector quantity whose
magnitude is a body’s speed and whose
direction is the body’s direction of motion.
Vicon application software uses vectors to
describe and analyze elements of
kinematic models of subjects or objects
whose motion is being analyzed. Also see
Kinematic model.
Vicon application software Software
for motion capture, processing, and
analysis by Vicon systems. A range of
software is available for use in a variety
of engineering, entertainment, and life
sciences applications. Also see
BodyBuilder, Plug-in, Polygon, Tracker,
Vicon iQ, and Workstation.
Vicon iQ Vicon application software
used for tracking and automatically
processing complex multiple-character
capture scenarios. Vicon iQ is the core
integrated motion capture and processing
software for entertainment applications.
