ADDITIONAL TIPS
Here are the following tips to help you in this step:
• Once you have selected a virtual point, you can adjust its position using the
arrows on your keyboard.
• The four anchor points you use to calibrate a camera angle should not be
aligned.
• Always match the points to the same edge of the lines.
• You can use more than 4 points to perform the calibration.
• If the 2
nd
and 3
rd
tests of the goal area calibration for a given camera are
excellent, you can use the position parameters (x,y,z) of this camera angle for
the central circle calibration of the same camera.
2.3.6 TESTING YOUR CALIBRATION
GENERAL TEST
Once you have calibrated all your camera angles, it is recommended to test them
using test snapshots of the playfield.
A general and quick test consists of drawing an offside line, and rolling it over the
calibration shots, to ensure that the offside line matches the following lines of the
field:
• the 16-meter line
• the 6-meter line
• the half-way line
Systematic tests based on test snapshots are explained in details below.
TESTING THE GOAL AREA
1
st
Test
Using the same view as your calibration shot, take an offside shot.
Check that the 16-meter line and 6-meter line are correctly matched.
If necessary, reposition the faulty anchor points.
