Optimize the calibration with the parameters

After the calibration, we might observe that one or several projectors’ pictures are not perfectly adjusted with the others.
First, check that there was no undesirable lights and nothing moving in front of the camera while you were performing the autocalibration.

*We highly recommend you to change parameters values one by one, and check the result by operating a calibration.

If one video projector is not well adjusted with the other projectors

• On the Output page, click on the Autocalib. button

• Select the group you were working with, and then click on Next until you reach Step 5.
• Adjust the Exposure parameter to get a better contrast

!We highly recommend you to let the Gain parameter to its default value 2.

If the overlapping area between two projectors is visible (highlight)

• Adjust the Exposure parameter to get a better contrast

• Perform a new calibration
• If the result is the same, go to Step 9 and check that you set up well the Binarization Threshold for the concerned Output(s)

If we observe that the calibration is not good enough between two projectors

• Go to Step 6 and adjust the Pattern size. You can increase it a bit

• Perform a new calibration
• If the result is the same, go to Step 7 and change the Deformation Tolerance from Normal to High

*Because theses steps are empirical, we recommend to adjust one parameter at a time, and directly perform an AUTOCALIBRATION.
