### How to calibrate camera
1. Prepare the checkerboard
- Print out "checkerboard.tif" found in "tahomastuff/library/camera calibration".
- It would be better to paste the checkerboard pattern on some flat panel like cardboard.
2. Capture the pattern
- In the Stop Motion Controller's "Settings" tab, enable "Calibration" box
- Click "Start calibration".
- Take 10 snapshots of the checkerboard pattern in various positions and angles.
- Once the capturing is done, calibration will be automatically applied whenever the "Calibration" box is checked.
3. Export & load calibration settings
- Calibration settings will be saved under "tahomastuff/library/camera calibration" with name "[MACHINENAME]_[CAMERANAME]_[RESOLUTION].xml"
- The settings file will be overwritten after finishing the new calibration.
- You can export the file for backup, or load it afterwards.
