== Calibration ==
'''Summary'''
:* Calibration determines each camera's location and orientation of the 3D Workspace so that the location of each marker can be obtained.
:* Calibration should be performed frequently.
:* Two types of calibration must be done:
:# [[#Dynamic calibration | Dynamic calibration]]
:# [[#Static calibration | Static calibration]]

If you reposition even one camera, follow these steps before calibration:
# Select '''Setup''' [[image: Vicon2.gif | 600px]] 
# Select '''Mask''' tab on the right
# Click '''Start Recording Background'''
# Click '''Stop Recording Background'''

=== Dynamic calibration ===
'''Summary'''
:* Calculates the relative positions and orientations of the cameras
:* Linearises the cameras
:* Tool required: 240mm calibration wand

'''Steps'''
# Click '''Calibrate''' [[image: Vicon4.gif | 600 px]] 
# Change the viewing pane to '''Camera''' (right below '''Setup''')
# Click '''connect/disconnect''' button (two red arrow heads pointing at each other) to connect to the Datastation. '''DataStation Connected''' and '''RealTime Connected''' icons should turn green from blue. If it turns yellow, check if the Datastation is turned on. [[image: Vicon12.gif | 700px]] 
# Make sure '''240_mm_Wand''' is selected
# Click on the first camera (1) and Shift-click on the last (12). This should show small camera views for all of the cameras
# Click '''Start Wand Wave''' [[image: Vicon8.gif | 300px]] 
# Move the calibration wand throughout the whole volume ('''important!''')
##Start on the outside of the volume, facing inwards
##Wave the wand in a vertical figure of eight in front of you while moving around the outside of the volume
##After a circuit, move inwards and continue spiralling
##Finish by crouching in the center, waving the wand in circles near the floor and spiralling up to head height '''Calibration screen-shot (you should be able to see it on the projector during the calibration)''' [[image: Vicon6.gif | 400px]] '''Camera positions''' [[image: CameraPosition.gif | 300px]] 
# Click '''Stop Wand Wave'''
# The calibration results will be shown in '''Status Report''' (''Awesome!'' is the best result, followed by ''Excellent!'', ''Good'', and then ''Bad''). All of the cameras should be in the ''Excellent'' or better. [[image: Vicon19.gif | 300px]] 

=== Static calibration ===
'''Summary'''
:* Calculates the origin or center of the capture volume and determines the orientation of the 3D Workspace
:* Tool required: L-Frame calibration object

'''Steps'''
# Place the L-Frame calibration object at the center of the capture volume or wherever you'd like the origin of your floor to be. The side of the L-Frame with two markers at the end is the X-axis, and the Z-axis is perpendicular to the floor.
# Click '''Track L-Frame''' [[image: Vicon11.gif | 300px]] 
# After a few seconds, click '''Set origin''' [[image: Vicon9.gif | 300px]] 
# Now you can save out your calibration

== Capturing a range of motion (ROM) trial ==
'''Summary'''
* A '''range of motion (ROM)''' trial is used to change the proportions of a basic/generic skeleton template (VST) that has generic marker positions to the physical dimensions of the captured subject (VSK)
* Basically, VSK file is a customized VST file. You can use one VST to create any number of customized VSK files; one VST can be used to create different VSKs to match different subjects' body proportions. The VSK file will make labeling much easier.
* VST files can be created using VICONiQ's '''Modeling''' mode. [[#Create a VST file | How to create a VST file]]

'''Steps'''
# Go back to '''Data Management''' and make sure you are in the session you want to be.
# Select '''Capture''' and then '''Live 3D workspace'''
# Type in a file name
# Select '''Type 2D Camera Data''' but not Realtime Output
# Click '''Start''' to start capturing a subject's movement [[image: Vicon10.gif | 500px]] 
# Have the subject start with a '''T-pose''', rotate all joints (wrist, lower and upper arms, shoulders, back, neck, head, etc.) one by one, and end with a '''T-pose'''.
# Click '''Stop''' to finish capturing
# Click '''Load Into Post'''; doing so will automatically select '''Post Processing''' mode [[image: Vicon13.gif | 200px]]

== Create a calibrated subject ==
=== Data Reconstruction ===
'''Summary'''
* Reconstruction turns the 2D camera data from all cameras into one 3D data file
* Poor calibration causes a poor 3D data

'''Steps'''
# Select '''Pipeline''' tab. If you don't see the tab, select '''Post Processing'''
# Double click on '''CircleFit, Reconstruct, Trajectory''' option. If the option is not available, click on the add button [[image:ViconIcon7.gif]] and double click on the '''CircleFit, Reconstruct, Trajectory''' option.
# Set the two parameters as follows:
## Min. Cameras to Start Trajectory: '''2'''
## Min. Cameras to Reconstruct: '''2''' [[image: Vicon14.gif | 300px]] 
#Then, select '''Show Advanced Parameters''' from the pop-up window. This should show additional parameters. Try the following:
##Delete single frame trajectories: '''Yes'''
##Min circle diameter: '''1'''
##Max circle diameter: '''30 to 100'''
##Circle fitting error: '''1.3 to 1.5'''
##Minimum circle fitting quality: '''0.45 to 0.5''' [[image: Vicon15.gif | 300px]] You may try different numbers depending on capture conditions and quality of the calibration 
#Right-click on '''CircleFit, Reconstruct, Trajectory''' and select '''Run Selected Op''' [[image: Vicon16.gif | 300px]] 
#Now you can see the markers in motion through the timeline.

=== Labelling ===
'''Summary'''
:* Labeling is basically the assigning of specific names to specific markers; you need to label markers since VICONiQ doesn't know which marker belongs to which part of a human body
:* If the movement is simple, you usually need to label markers in a single frame
:* There are 4 different modes for labelling, but you need to know only two:
:#'''Single''' allows you to assign just one marker at a time
:#'''Sequence''' allows you to sequentially select markers and identify which ones they are
:* There are also 4 different rules for how the label is assigned to the marker through time:
:#'''Forward''' assigns the markers from the current frame
:#'''Backward''' is the opposite of Forward
:#'''Whole''' assigns the entire markers as long as they exist. Useful if markers don't swap or get confused with one another
:#'''Range''' labels a range of markers

'''Steps'''
# Select '''Post Processing''' and select '''Subjects'''
# Click '''Create Vicon Skeleton Template (VST)'''
# Select a VST file (for a full-body capture, choose '''iQ_HumanRTKM_V1.vst''' under C:\Program Files\Vicon\Models\VICONiQ2.0) and type in a name [[image: Vicon17.gif | 300px]] 
# Select '''Labelling''' and click '''Sequence''' and '''Whole''' [[image: Vicon18.gif | 200px]] 
# In '''3D Workspace''', manually label markers as follows (for the labels, please refer to '''"Where to place markers"''' on '''p.28''' of VICON System Manual)
##Select a label (LFHD, RFHD, etc.) from the list
##Click a corresponding marker (white dot) in '''3D Workspace'''
#Go to '''Pipeline'''
#Make sure to set the current frame to the frame that was labeled in the previous step.
#Right-click on '''Autolabel Range of Motion''' and select '''Run Selected Op''' (if the operation is not available in the list, add the operation by clicking [[image:ViconIcon7.gif]]) This will auto-label the rest of the frames in the ROM trial.
#Also run '''Delete Unlabelled Trajectories'''
#You can check trajectories continuity by looking '''Continuity Chart'''

=== Subject calibration ===
'''Steps'''
#Make sure you are in a T-pose frame. Select '''Subjects''' tab
#Make sure that the '''Active Subjects''' box is on '''Edit''' mode.
#Select '''G''' button and then '''T''' button. Now you should see a blue T on the timeline.
#Click a small button next to '''Calibrate Subject''' button.
#In the option window, set '''Calibration Quality''' to '''Medium'''. Also, if you set '''Autosave''' to '''Yes''', then VSK will be saved automatically; otherwise, export VSK manually later.
#Finally, click '''Calibrate Subject'''. You should see your "sticks and boxes" subject model (if you don't see this, go to the '''View Options''' tab on the left and make sure the '''subjects''' box is checked).

== Capture ==
'''Summary'''
*Capture is the same as what you did for the [[#Capturing a range of motion (ROM) trial | T-pose]].
*Make sure that the range of motion (ROM) trial is in a good quality. If not, re-calibrate the system and re-capture a ROM trial.

'''Steps'''
# Go back to '''Data Management''' and make sure you are in the session you want to be.
# Select '''Capture''' and then '''Live 3D workspace'''
# Type in a file name
# Select '''Type 2D Camera Data''' but not Realtime Output
# Click '''Start''' to start capturing a subject's movement
# Click '''Stop''' to finish capturing
# Click '''Load Into Post'''; doing so will automatically select '''Post Processing''' mode

== Process and edit the data ==
'''Summary'''
*At this point, you should have the VSK file created for the subject, so you do not need to manually label all the markers for each trial.

'''Steps'''
# Select '''Pipeline''' tab. If you don't see the tab, select '''Post Processing'''
# Double click on '''Load Subject(s)''' option. Check if the VSK file that you created in the subject calibration step is selected as '''Input File Name(s)'''. If not, click on the browse button and find the VSK file. Set '''Yes''' to '''Use File Name''' option.
#Right-click on '''Load Subject(s)''' and select '''Run Selected Op.'''
# Double click on '''CircleFit, Reconstruct, Trajectory''' option. If the option is not available, click on the add button [[image:ViconIcon7.gif]] and double click on the '''CircleFit, Reconstruct, Trajectory''' option.
# Set the two parameters as follows:
## Min. Cameras to Start Trajectory: '''2'''
## Min. Cameras to Reconstruct: '''2'''
#Then, select '''Show Advanced Parameters''' from the pop-up window. This should show additional parameters. Try the following:
##Delete single frame trajectories: '''Yes'''
##Min circle diameter: '''1'''
##Max circle diameter: '''30 to 100'''
##Circle fitting error: '''1.3 to 1.5'''
##Minimum circle fitting quality: '''0.45 to 0.5'''
#Right-click on '''CircleFit, Reconstruct, Trajectory''' and select '''Run Selected Op'''
#Also right-click on '''Trajectory Labeller''' and select '''Run Selected Op'''. This automatically labels all markers by using the VSK file.
#Check if markers are labeled correctly. If not, correct labels using '''Single''' and '''Forward''' under '''Labelling'''. '''Continuity Chart''' is again helpful.
#Go to '''Pipeline''' and run the following operations in the order by right-click and selecting '''Run Selected Op'''
##'''Trim Tails''' will remove unreliable trajectory data
##'''Filter Using a Butterworth Filter''' will remove frequencies that are inconsistent with the markers
##'''Fill Gaps using Splines'''
##'''Kinematic Fit''' will fit the kinematic skeleton into the markers using the VSK file
##'''Fill Gaps using Kinematic Model''' will filing in missing data from occluded markers
##'''Delete Unlabelled Trajectories''' (note: run this operation only if you don't have any mislabeled trajectories, that is, '''Trajectory Labeller''' operation has been successful)

== Export the data ==
'''Steps'''
# Select '''Pipeline''' tab under '''Post Processing'''
# Run one of the following operations by right-click on the operation and selecting '''Run Selected Op''':
:*'''Export data to C3D file''' for use with MotionBuilder
:*'''Export motion to V-file''' for use with Maya or MotionBuilder
:*'''Export data to CSM file'''; doing so will produce xyz marker coordinate values and export to a single file.
:*'''Export data to CSV file'''; doing so will produce all joint parameters and gait parameters. You can directly load them into Excel.
:Note: if the operation you need to perform is not available, click on the add button [[image:ViconIcon7.gif]] to add the operation

== Create a VST file ==
'''UNDER CONSTRUCTION'''

'''Summary'''
:* VST files can be created using VICONiQ's '''Modeling''' mode
:* You are creating bones and joints by creating segments.

'''Steps'''
# [[#Capture | Capture]] a trial.
# After selecting '''Load Into Post''', go to Pipeline and run '''CircleFit, Reconstruct, Trajectory''' and '''Export data to C3D file'''
# Go to '''Modeling'''
# Go to '''File''' and select '''Clear'''
# Import C3D file which you exported
# Choose '''No''' for T-Pose, and enter a single frame #.
# On the '''Outlier''' tab, click '''Root'''
# Click '''Manipulate''' and move a small box with three arrows. This is your first joint, so place it at an appropriate position. You can click-drag the screen to change the view.
# Make a segment that connects two joints by doing the following:
## Click '''Select''' and click the joint (Joint A)
## Click '''Segment''' and click anywhere to create a new joint (Joint B)
## Click off '''Segment'''. Now you see a new segment that connects Joint A to Joint B.
## Click '''Manipulate''' and move Joint B to an appropriate place. You may also want to change the joint type (Free, Hinge, Rigid, etc.)
# Repeat the previous step to create all the remaining segments
# You also need to create markers:
## Click '''Select''' and then '''Marker'''
## Click on the screen to create a marker. You'll see all newly created markers under '''ModelMarker''' of '''Outlier'''. You should always rename markers so it is easy to identify them later.
## Click off '''Marker'''
## Click '''Manupulate''' and marry the marker you created with the real marker captured by the cameras.
# Repeat the previous step to create all the remaining markers.
# Go to '''File''', select '''Save as''' and save your VST under the correct directory.

'''TIPS'''
:* Use '''Alt''' key and mouse to rotate the view
