Calibration Procedure
Perform 2D camera calibration and laser calibration independently.
• In order to perform the calibrations, users can follow step (1)~(11) as indicated
below.

• If only 2D calibration to be performed, execute step (1)~(6). If the calibration
result is not good, repeat 2D Resolution and Camera Rotate steps several times
until the [OK] message appeared.
• Execute step (7)~(11) for laser calibration.
2D Camera Calibration
1. 2D Resolution: Calibrate 2D camera resolution approximately.
2. Fiducial Setting: Set up Fiducial Mark.
3. Dot Board Rotate: Rotate calibration board if necessary.
4. Camera Rotate: Rotate 2D camera if necessary.
5. 2D Resolution: Calibrate 2D camera resolution precisely.
6. Camera Rotate: Re-confirm 2D camera angle.
Laser Calibration
7. 2D Offset: Align the coordinates of X-ray tube, scanned image and 2D image.
8. Amplifier: Set up amplifier to increase the accuracy of laser detection.
9. Laser offset: Use square hole’s position for laser positioning.
10. Zero Shift: Set up zero height for all Laser Sensors and Amplifiers.
11. Laser Sensor: Input the information of Laser Sensors and Amplifiers to registries.
Start the Calibration
Input the calibration board into the machine manually. Put tape on the calibration board
(as shown below) by leaving one row circle and one column circle at the upper-right
boundary. Make sure that the calibration board surface is clean.
