MAIN CAMERA CALIBRATION
You need three calibration shots to calibrate the central camera:
• Left penalty area
• Central circle
• Right penalty area
Important
Keep the following in mind when you select the frame you will use:
• A playfield is naturally curved, whereas the Epsio virtual field is made
up of straight lines.
• A very wide shot is very likely to distort the image, which will intensify
the curved effect of the field.
Goal Area Calibration
The snapshots for the goal area of the main camera should show the following
elements:
• the central line
• the whole left/right penalty area (depending on the shot)
The shot should be as close as possible while containing the above-mentioned
elements.
