Introduction to data processing

After the capture is finished the data must be processed in QTM to get 3D data, 6DOF data and force data. Some functions in QTM, such as AIM and exports, can also be performed in processing. The processing can be done automatically after the capture, manually in the current capture file, see chapter Reprocessing a file, or automatically on saved files by using Batch processing, see chapter Batch processing.

The settings of the automatic processing, which are the same for the processing directly after capture and batch processing, are specified on the Processing page in the Project options dialog. The only exception is the Auto backup option which is only available when making a measurement and batch process.

The following processing steps are available on the page:

• Auto backup, see chapter Auto backup.
• Pre-process 2D data, see chapter Processing 2D data.
• Track the measurement
  • 3D, see chapter 3D tracking measurements.
  • 2D, see chapter 2D tracking of data.
• Merge with Twin slave, see chapter Working with QTM twin files.
• Gap-fill the gaps, see chapter Trajectories.
• Apply the current AIM model, see chapter Automatic Identification of Markers (AIM).
• Calculate 6DOF, see chapter 6DOF tracking of rigid bodies.
• Solve Skeletons, see chapter Tracking of skeletons.
• Apply SAL, see chapter How to use SAL.
• Calculate force data, see chapter Force data calculation.
• Calculate gaze vector data
• Export to TSV, see chapter Export to TSV format.
• Export to C3D format, see chapter Export to C3D format.
• Export to Matlab file, see chapter Export to MAT format.
• Export to AVI, see chapter Export to AVI file.
• Export to FBX file, see chapter Export to FBX file.
• Export to JSON file, see chapter Export to JSON file.

The settings of each processing step can be found in the tree to the left in the dialog. For information about the settings, see chapter Project options.
