VIRTUAL OFFSIDE LINE
TECHNOLOGY TO ASSIST OFFICIATING
WHAT IS THE CURRENT STATE OF VOL?
Virtual Offside Line Technology
-
Is a manually controlled, replay-only system
-
Uses a VAR system to manually review and replay multiple game camera POVs from a central repository
-
Uses 3-D, virtual, broadcast enhancement technology to manually insert virtual reference lines in a static video image
The VOL Process
-
Manual STEP 1: Find the POV and video frame when the offside pass originated.
-
Manual STEP 2: Find the best POV(s) showing the atttacker and defender at the moment the pass originated.
-
Manual STEP 3: Select and click on the relevant body parts of the attacker and defender in the video frame.
-
Automatic STEP: SMT-VOL instantly produces a graphically enhanced VOL image for review.
-
Manual STEP 4: The offside decision is rendered based on analysis of the VOL image for review.

HOW CAN VOL IMPROVE?
Execution Time
-
VOL process requires four manual steps and thus takes an indeterminate amount of time to execute.
-
VOL processing time can negatively impact the flow of the game.
Precision
-
VOL produces a result that is precisely accurate.
-
VOL produces a result that is precise beyond what humans can achieve in a live scenario.
-
VOL produces a result that is precise beyond the original intent of the offside rule.
WHERE CAN VOL GO IN THE FUTURE?
Can the Manual, Replay, VOL Officiating Assistance process be improved by introducing state-of-the-art live broadcast enhancement concepts from other sports around the world?

VOL through the Lens of OASIS


AUTOMATED, LIVE VOL OFFICIATED SYSTEM
Steps to an automated live VOL
-
Adopt an OASIS Approach to the On-Site and Centralized Architectures
-
Mandate minimum certification standards for Live, Real-time, Computer Vision Tracking of the Ball (3-D), and Players (2-D)
-
Incorporate an Eventing Intelligence Engine (EIEIO) for Live Computer Algorithm Event Detection of Ball Possession and Pass Initiation
-
Adopt an "Automated Offside Rule Set"
Steps to a live, real-time, automated offside-detection system
-
To call Offside behind the scene and assist game Officials with audible tones
-
To call Offside and to visually display Offside status in the stadium
-
To enhance broadcast video with a moving and color contextual Offside line for fan engagement
-
To automatically call Offside live in a match
