2.3.3 How to Calibrate the Cameras

Note

The calibration steps explained in the sections below illustrate the calibration

of the two 16-meter cameras used with the offside line tool. However, the

same procedure applies to the calibration of the free camera for the live

tools.

Once Epsio is open, you calibrate the various cameras in the

CALIB

tab, in the following

way:

Add a virtual camera for each physical camera to be calibrated, by clicking the

Add

button corresponding to the requested camera in the

Creation

area:

The camera angles to be calibrated for the corresponding camera preset are added

as frames including the virtual playfield in the Camera Angle list:

Using the Preview channel, make snapshots of the real playfield corresponding to

each calibration angle in the following way:

In the Camera Angle list in Epsio, click the camera angle to which you want to

associate a snapshot.

Pause on the requested frame in the preview channel.
