Configuration 23
The camera angles defined in Epsio are now associated to snapshots of the real
playfield and saved in a configuration file. You can load them back via the File >
Load menu. See also the section 2.1.3 ‘Saving and Managing the Configuration’,
on page 10.
7.
Use varied test snapshots to make sure the calibration is acceptable as a whole. If
necessary, perform some adjustments by repositioning only the anchor points
initially matched in step 3.
For more information on the calibration tests, see the section 2.3.6 ‘Testing your
Calibration’, on page 32.
8. On a shot that includes the 16-meter line, and part of the central circle, add virtual
points for offside shots where playfield lines would not be visible.
For more information on additional virtual points, see the section 2.3.7 ‘Adding
Virtual Points’, on page 35.
2.3.4 Snapshots for Calibration
16-Meter Camera Calibration
Introduction
For each 16-meter camera used for the offside feature, you need to take two snapshots
corresponding to each camera angle:
•
Goal area
•
Central circle
Warning
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 snapshot for the goal area of the left or right 16-meter camera should show:
•
the whole left or right penalty area (respectively) with the 16-meter and 6-meter lines
•
the goal line along the goal area,
•
part of each touchline on both sides of the playfield.
Warning
The touchlines should be parallel to the horizontal borders of the frame, and
the zoom should keep the distortions of touchlines as low as possible.
