Scene setup

Set the projectors and camera as follow:

  • Video projectors need to cover the entire dome, and have enough overlap between each other to get a seamless projection
  • The calibration camera needs to be as aligned as possible with the top-middle of the dome

The resulting setup should be similar to the following schematic

A schematic depicting a typical setup for autocalibration

The projection should look like similar to this:

An example of projectors setup for autocalibration

We can see here that the entire projection surface is covered by the video projectors and that we have enough overlap between each projector.

Prepare the environment

  • Any light – natural or artificial – should be off or hidden
  • Any reflection in the room can mar the autocalibration operation

Prepare the video projectors

Take care that the following settings are setup in your projectors:

  • All projectors are connected with a video cable to the V-Node server whose outputs are running autocalibration

Prepare the camera

Take care that the camera :

  • is connected to your POE Switch with the appropriate lens
  • can see the entire projection zone
  • has its aperture fully open. (manual setting on the lens)

Depending on the surface you are projecting on, you may need a different lens for the camera.

In this example we are projecting on a dome so the camera is equipped with a wide angle lens.

Configuring the camera software

Depending on the camera you are using, follow one of these guides to setup the camera on the Kinetic Designer workstation:

We are now good to open Modulo Player software.
