devices. It connects with a push and a

twist. Also see LEMO® connector.

BOB Break Out Box. A hardware unit in

Vicon V-series systems used to connect

one to three cameras to a single port on

the Datastation. Also referred to as a

Camera Interface Unit. Also see

Datastation.

BodyBuilder Vicon application software

for kinematic and kinetic modeling, which

reduces complex 3D vector algebra into a

simple scripting language, called

BodyLanguage. Also see BodyLanguage,

Pipeline, Plug-in Modeler, and

Workstation.

BodyLanguage A scripting language

used in BodyBuilder to create

biomechanical models. Also see

BodyBuilder.

Bones See Segment.

Bounding box A semitransparent 3D

box drawn around each segment defined

in the kinematic model for a subject (as

specified in the .vsk or .vst file). This

display is optional and is used for

visualization purposes only. Also see

Subject, .vsk file, and .vst file.

Burn-in window See Video Burn-in

window.

C

.c3d file A binary file with extension

.c3d, which contains among other details,

the 3D reconstructions of video data,

unlabeled trajectory data, analog data,

and parameters. Vicon application

software creates .c3d files when it

reconstructs and saves video data

captured by the Vicon system. By default,

.c3d files are saved to the active Session

folder of the open database. This is a

public domain file format that also can be

read and written by third-party

applications (for further details, visit

http://www.c3d.org/

). Also see Analog,

Eclipse database, Label, Reconstruction,

and Trajectory.

Cadence A temporal parameter used in

gait analysis for the number of strides the

subject takes per minute. Also see Gait

analysis.

Calibration See Autolabel calibration,

Camera calibration, Floor plane

calibration, and Subject calibration.

Calibration health check The process

by which some Vicon application software

determines the state of each camera,

provides information about possible

reflections in a camera’s view, and

identifies any cameras whose calibration

may need to be repaired. Also see

Camera calibration and Camera

calibration repair.

Calibration kit A collection of

specialized Vicon calibration objects for

use in the Dynamic Calibration (DynaCal)

process for calibrating Vicon systems and

cameras. Also see Calibration object and

Camera calibration.

Calibration object A specialized piece

of equipment used to calibrate the

capture volume and Vicon cameras.

There are two basic types of calibration

object: a frame and a wand. Both types

are typically made of metal and have

retroreflective markers attached.

The Vicon application software uses the

known physical dimensions and distance

between the markers on a calibration

object to calculate calibration

parameters. Also see Calibration kit,

Calibration wand, Camera calibration,

and Static calibration object.

Calibration reference object file See

.cro file.

Calibration volume The three-

dimensional area of the capture space
