6. Load the test snapshots, and perform the necessary 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 24.
7. 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 27.
2.3.4 GOOD SNAPSHOTS OF THE PLAYFIELD
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
For the main camera used for the live tools, you need to take three snapshots
corresponding to each camera angle:
• Left angle
• Center angle
• Right angle
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.
