2.6 Saving and Restoring Parameters
All of the parameters that control the operation of the SVS Stereo Engine can be saved to a file for
later use. Parameter files can be loaded and saved using the File menu: Load Param File and Store
Param File.
The file data/megad-75.ini contains a sample file for a 7.5 mm lens on the MEGA-D stereo rig.
It serves as an example of the settings available through parameter files. In practice, these settings are
usually computed using the calibration program, and then saved to a file for later use. But, it is also
possible to change the settings directly in the file.
