    Digitizing New Data
  1. Click "Initialize". The control will prompts you for the number of cameras that are being used. For almost all XROMM applications, the answer is 2.
  2. You will be prompted for Camera 1 and Camera 2 UNDTFORM files.
  3. Next, you will be prompted for two movie files. The two videos will appear in the video window.
  4. The program will ask if the cameras are calibrated via DLT. Assuming that they have been created, pick the DLT coefficients file (the merged file DLTcoefs.csv for all cameras). You are now ready to digitize.
A window will open with all camera views for the video sequence loaded. In the example below, two cameras were loaded with camera 1 in the left panel and camera 2 in the right.


 

Identify the frame you would like to begin digitizing and navigate to that frame by typing in the number into the Frame number box or by sliding the scroll bar.
To track a single point manually:
  1. Choose the autotrack mode desired. Pick "off" or "auto-advance" to manually digitize the point. "Off" requires to user to manually advance frames, while "auto-advance" will advance to next frame once the point is manually clicked.
  2. Make sure the point you are tracking is selected in the Current Point drop down menu.
  3. Click the point in one camera view. A blue line should appear in all other views and should be running through the same point in the other camera views.
  4. Click the point in a second camera view. A green diamond should appear over the red circle in all camera views. The red circle is the value recorded as position data in the spreadsheets generated.
  5. Advance to the next frame a repeat.
To track a single point automatically:
  1. Choose the autotrack mode desired. Pick "automatic" or semi-automatic" to automatically digitize the point. "Automatic" will autotrack the point for as long as it can and will automatically advance frames, while "semi-automatic" requires input from the user to advance the frame.
  2. Make sure the point you are tracking is selected in the Current Point drop down menu.
  3. Click the point in one camera view. If autotracking, the program should automatically follow the point just clicked. If the red circle goes off the point or the user desired to stop autotracking, pressing "x" will stop the tracking.
  4. Once sequence is completely autotracked in one camera view, return to the beginning of the sequence and autotrack in the next camera view.
To track multiple points automatically:

Multi will automatically track multiple points simultaneously. This option will automatically track multiple points simultaneously.

  1. Select multi.
  2. Create and click all of the points you want to track.
  3. Hold SHIFT and click or middle mouse click anywhere on the image.
  4. Release the SHIFT key. Pressing "x" will stop the autotracking midstream.
