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
