2.3 CALIBRATING THE CAMERAS
2.3.1 I
NTRODUCTION
In Epsio, calibrating the cameras consists of positioning a virtual playfield in a 3D
environment to match the position of the actual playfield used for a given event.
You calibrate the cameras in the Calibration tab in Epsio.

ALIBRATION
When you use the offside line tool, you usually calibrate two 16-meter cameras for
an event: a left-angle camera and a right-angle camera. However, Epsio allows
you to use other cameras.
You calibrate each 16-meter camera on two angles: looking at the goad area, and
at the central circle.

ALIBRATION
When you use the live tools, you calibrate the camera that is directly connected to
Epsio via the IN2 Connector. For this physical camera, you will calibrate a main
camera in Epsio. The three angles (left, center and right) are automatically added
to the Camera Angle List when you add a main camera in the Calibration tab.
Important
Only calibrate your cameras when you have validated the camera
position, height and orientation. These should no longer change after the
calibration.
