On the Output page click on Autocalib.

The autocalibration process has 10 clear steps, click on Next when you get ready.

Step 2 : Create a group of projectors

  • Add a Group, you can rename it
  • Select it to highlight the group and click on Next

Step 3 : Add Outputs to the group

  • Drag & Drop each output from the right part to the left part which is the Group
  • When it’s done, click on Next

Step 4 : Assign the camera

  • On the right side you should see the camera we prepared
  • Drag & drop the camera from the right side to the left side called “Current Camera
  • Click on Next

Step 5 : Adjust the camera position and its aperture

  • This window give you a middle cross to set the camera position/orientation in the center of the dome
  • You can check again as well if your projectors have enough overlapping area between each other
  • Adjust the aperture on the camera to get the best constrast (not too bright, not too dark)
  • If needed, move the Exposure cursor to be more precise. This parameter needs to remain an additional setting to the aperture setting.

  • Adjust the Image crop parameters to fit to the interested area of the projection surface

Step 6 : Adjust the Pattern size that will be used for the calibration

  • Depending of your projection distance and the projection surface dimension, you’ll have to adjust this parameter.
  • Generally we recommend to move the cursor until you get around 20 points per projector.

Step 7 : Select the type of your projection surface, and the degree of Deformation

  • In this exercice we project on a dome so we chose this type here
  • For the Deformation tolerance we usually start with the default value which is Normal

  • Depending of the result of the first calibration, we could increase the Deformation tolerance to High for a second calibration

Step 8 : Define the mask around the projection surface

  • Use the tool + to add points around the surface
  • To acchieve a curved surface like our dome, keep your click on if will create a curved shape

  • Then, you can adjust/move/these points thanks to the other tools of the panel

Step 9 : Adjust the Binarization threshold to make in indicate in blue what the projector see

  • Adjusting the Binarization threshold defines what the calibration will consider on the picture for each projector
  • The blue color represents what each projector can project on the dome, basically we need to fill in blue what the projector sees.

Step 10 : Autocalibration is running

  • In this final step, Kinetic Designer displays pictures on each projector one by one
  • The camera record these pictures
  • At the end of this step, you should have a Success pop-up, click OK

  • All the projectors of your group should be now calibrated

How to adjust the perspective of the calibration deformation ?

Once the calibration is done, you could need in some cases to warp the entire picture of your group of projectors.

  • To do so we click on Global Warp

  • Go now to the Shape tab and then click on ON in order to enable the warping

  • As you use to do with usual Warping, by click on Configuration you can add columns and rows if needed
