.csm file

Vicon MX Hardware System Reference Glossary-7

contains configuration entries for each of

the calibration objects supplied in the

Vicon calibration kit, so they can be

selected in Workstation application

software. These .cro files are installed in

the Vicon Calibration Objects folder (by

default, C:\Program Files\Vicon\System

\CalibrationObjects). Also see Marker,

Calibration kit, and Calibration object.

.csm file Character Studio Motion

capture file. A text file with extension

.csm, which contains capture data from a

Vicon system in a format that can be

used by 3D Studio Max. This file is

created by a pipeline operation in some

Vicon application software and saved in

the active Session folder of the open

database. Also see Capture data and

Pipeline.

D

Data acquisition The process by which

Vicon motion capture and analysis

systems convert information from real-

world sources to digital form in which it

may be stored, manipulated, analyzed,

and displayed. Also see Data streaming

and Motion capture.

Data capture See Motion capture and

Movie capture.

Data file Related pieces of data

organized in a specific manner. Data files

contain information but not instructions

or programs.

Data streaming The passing of real-

time motion data from some Vicon

application software to Vicon or third-

party visualization software. Also see

Data acquisition, Motion capture, and

Visualization software.

Datastation In Vicon V-series systems,

a Vicon hardware unit that captures and

synchronizes all Vicon camera and analog

data. This unit provides the link between

the Vicon cameras, the host PC running

the Vicon application software, and any

third-party analog devices. Also see

Analog, Host PC, and Vicon V-series

system.

DCAM Instrumentation and Industrial

Control Working Group (IIDC) 1394-

based Digital Camera Specification. A

standard for digital cameras that output

uncompressed image data without audio

and are to be connected to a computer

using an IEEE 1394 connector. The Vicon

Reference Video option supports the

Basler range of DCAM cameras. Also see

IIDC 1394 and Reference video.

Degree of freedom (DOF) An

indication of how freely a joint is able to

move (translate or rotate) in respect to

its parent segment. This is expressed as

the minimum number of coordinates

required to completely specify the

rotational (Rx, Ry, and Rz) and/or

translational (Tx, Ty, Tz) movement of the

joint.

0 DOF indicates a fixed joint with no

rotational or translation freedom. 1 DOF

indicates a hinge joint with rotational

freedom around a single axis. 2 DOF

indicates a universal joint with two

rotational degrees of freedom around two

orthogonal axes. 3 DOF indicates a ball-

and-socket joint with full rotational (but

not translational) freedom. 6 DOF

indicates a free joint with full

translational as well as rotational

freedom. Also see Rotation and

Translation.

Depth of field The distance between

the nearest object in focus and the

furthest object in focus within a scene as

viewed by a particular camera lens.

Outside this area, moving towards or

away from the lens, the focus becomes

progressively less sharp and the image

appears out of focus. Depth of field varies
