NRL continues trialing Hawk-Eye technology to aid video referees

NRL set to introduce Hawk-Eye technology for second half of season
by Andrew Webster

The NRL is set to usher in revolutionary Hawk-Eye technology that will allow the Bunker to determine if players are offside from kicks - and possibly as soon as this season.

In the game's most significant technological advancement since the introduction of the video referee two decades ago, it can be revealed that officials have been secretly trialling the system in the early parts of the season, including at the Auckland Nines.

If it is convinced the system is 100 per cent accurate, it is likely to be in place by round 13.

The innovation is different to the much-hyped 10-metre offside line proposed by Fox Sports, which has now abandoned the idea.

Fox Sport's virtual line would have shown if players were offside in general play and in try scoring situations.

In essence, it was for entertainment purposes only as part of the network's new dedicated rugby league channel launched earlier this year.

But the NRL wants its system to become a cornerstone of its decision-making process.

As it stands, the Bunker cannot rule on players standing offside but can rule them offside from kicks when tries are scored, however, standard camera angles are often misleading and unreliable. Given how prominent the cross-field kick has become as an attacking weapon, this is a significant development.

The problem rests with the various shapes and sizes of the humble footy ground.

Most are not flat, meaning the technology isn't completely accurate when regular television cameras are used.

So the NRL has been laser-scanning grounds to take into account uneven surfaces. At WIN stadium, for example, there is a substantial mound in the middle of the ground.

When headquarters is convinced the system is foolproof, NRL chief executive Todd Greenberg will make a decision on whether to introduce it to the Bunker.

All concerned parties were reluctant to speak about the story when contacted on Thursday, but it comes at an interesting time.

Hawk-Eye's goal-line technology has been used in many European leagues - including the Premier League - for several years.

But, earlier this week, Hawk-Eye technology was used in a football friendly between France and Spain at Stade de France to determine off-side.

It was the system's most high-profile test to date and it worked spectacularly.

It ensured that Antoine Griezmann's goal for France was correctly denied for offside while Gerard Deulofeu's strike for Spain was correctly given. The second decision took the video referee just 40 seconds.

The next day, the Premier League declared it wouldn't use the technology until at least the 2018-19 season, although it could be used in FA Cup matches from next year.

I hope that is of assistance.

Haven't seen it mentioned anywhere until this. Totally agree with Keary, totally against Hawkeye in our game. I would say I can't believe they're considering it but it is the NRL we're talking about.

https://www.foxsports.com.au/nrl/nr...s/news-story/3d816d69ccaf5c2d82b5796d17ac0bbf

After Round 19 was dominated by contentious forward passes the NRL has vowed to adopt new hawk-eye technology to give fans more of a definitive response to rulings on the field, according to News Corp.
However Roosters playmaker Luke Keary believes the move will lead to more stoppages that will ruin the spectacle of the game.

“I’m a no. The technology doesn’t suit us,” Keary said.

“We are just a natural kind of game. If you slow down every try and say he has thrown it here and caught it in front.

“People don’t understand when you are running fast the ball is sometimes going to travel forward, but you have thrown it back out of the hands.

“It just brings in a whole other grey area. Then people start complaining that the game is slowing down because they are going up to the video referee to look at it.

“I’m happy to live with it. Over the course of your career they are going to go both ways. It is just the way the cards fall. It is our game. We’ve all grown up with it. Just get over it.”

A number of contentious rulings in Round 19 had fans venting their frustration over the inconsistency with technology in the game.

The Warriors were robbed against the Eels, when Roger Tuivasa-Sheck was called for a forward pass in the build-up to a potential matchwinning try.

The Storm’s golden point loss to Manly was decided by a forward pass, which led to Daly Cherry-Evans kicking the match-winning field goal in the next set.

Braidon Burns’ pass to winger Campbell Graham in the Rabbitohs win over the Dragons was questionable at best and Roosters coach Trent Robinson was dumbfounded Cooper Cronk was denied a try after James Tedesco’s last pass was ruled forward in their win over the Bulldogs.

The NRL are keen to introduce hawk-eye technology to track the movement of the ball as it leaves the player’s hands during a try-scoring moment.

The technology will be similar to that used by tennis for close line calls, the EPL for off-side play and lbw decisions in cricket.

“The only way we can be 100 per cent certain and consistent with forward passes is with this hawk-eye technology,” NRL head of football Graham Annesley said.

“The company’s engineers have told us they can develop a system where it can identify even in the closest margins if the ball has been thrown backwards or forwards from a player’s hands.”

Keary leapt to the defence of the referees, despite another weekend full of controversial moments.

“As a game we tend to just bag them,” Keary said.

“They are humans and they make mistakes. The players make mistakes. The coaches make mistakes.

“The referees are going to make mistakes, but we seem to higlight their mistakes more than the players. It is going to happen and it is part of the game.

“It gives us something to talk about on Monday, but I think they are doing a good job. You can have all the technology you want and they will still make mistakes because they are human.

“I think as a game we need to relax a little bit and let them relax and they will probably do a better job.”

The Warriors forward pass and Souths non-call for a forward pass will normalise refereeing mistakes to the point, that when the finals come around, betting on matches will be a killing for the lucky few.

The way to go is to put GPS in the ball.............
A tracking device in each end of the ball (if possible) would indicate the orientation of the ball which may be useful. Since they're already on the players as well:
  1. Take a reading of the forward velocity of the player and the ball immediately leading up to and at release
  2. If the net difference exceeds a small margin of error it alerts the bunker
  3. Bunker reviews and notifies on-field ref at their discretion
  4. The RL community continues to shout the house down when an imperfect system occasionally fails

Given that Bunniesman is a member of MENSA - he should be able to do all of these calculations in his head.

Now just try running with a ball in your arms

You naturally swing you arms as you run. So the ball is moving backwards and forwards as you are running in a forward direction

You could only sync forward momentum of the ball carrier to a players GPS at the back of his neck

Against

The ball once it leaves the hands and is floating in the air

You would have to measure a players velocity in his last 1 to 2m of running

And you could only use 1 to 2m of ball travel as well

But as it happens so fast and so many match day passes it could only be judged by a computer in realtime

I think 0% forward tolerence would be fine. 5% would already be a obvious forward pass

Not sure how a spinning ball would effect things if the chip is on its surface

In all seriousness surely we have the technology that when a pass is thrown it can be determined if it went backwards by how many likes it receives on Facebook.

I had velocities leading up to the pass in mind as players can get hit on passing which brings things to a halt. The tolerance would be affected by the position of the ball in the hands relative to the back GPS sensor, and could bring up endless false positives if detected by computer. Maybe a system where the bunker ref spots a suspect pass, picks the pass out of a replay and the computer adjudicates on the relative velocities based on a human selected time-stamp. Or perhaps its time to enforce GPS gloves.

Pretty sure soccer uses GPS technology for the ball in-goal, so I'd imagine that the technology can account for the ball's rotation.

Yes because f**k me if we can't actually hire and train some competent sideline officials who know the difference between backwards and forwards.

C'mon, this is the NRL we are talking about. We'll be lucky if they even put $100 towards this

Save money and fitness by having touch judges at every 10 metre interval so that the lazy, inept, wankers don't have to move. Kinda like Pride MMA in Japan where the ring was surrounded by refs who could push the fighters back into the ring if they fell out.
