Goal Line Technology in NHL

[nturn06]

Honestly how accurate/precise do you think this tool is?

It can measure the actual possition of the puck to within 1 mm (+/- 2 m).

Im assuming that +/- 2m is a typo? Did you mean mm?

If the error is 2 mm, then how can you say it measures the position of the puck to 1mm?

Any source for this claim? Not being a dick but I'd like to read more about it.

The reality is that given the puck velocity, and the fact that it is not a ball, the error of puck tracking technology is likely worse than the current eye test.

And, I think that relying on it would open a new can of worms: what if it is clear that the puck did not cross the line, but the puck tracking technology says it is a goal?

Puck would need a gyroscope in it, to figure out the axis of the puck.

If it’s so easy, then design an economical system and sell it to the league.

If they contracted me to design it, I would.

If the NHL had even the slightest desire in implementing this technology, it would have already been developed, which tells me that they have no interest in it. As a result, I have no interest in developing a technology that has little to no marketability.

I do have my own businesses though that do very well for themselves, so don't cry for me.

Watching refs taking 7 minutes to decide if its a good goal or not by Perfetti, if soccer can implement goal line technology why NHL do not have this technology yet, since we already have puck tracking technology its baffling they are unable to say if a puck cross the line completely, its 2025 and refs watching an ipad trying to toss a coin if puck is in or not is hilarious and so outdated, this is what happens when league is run by dinosaurs lol

What do you suggest could be used to determine all of the puck completely crossed the goal line? Puck sensors are inside the puck, so that’s not providing a 100% accurate account of where exactly the edges of the puck is.

Width and height of the puck is already known, all you would need to know is angle. Sensors do not need to be wired or electrically embedded sensors, so they can be placed on the very leading edge around the perimeter of the puck without concern of a failure due to impact. Then it is just a matter of generating an algorithm to determine position relative to angle of the puck and compare spatially to the interior boundary of the goal line, or if used for high sticks, set a pre-determined height (or heights since we have shoulder height for high sticks, and cross bar for deflections), etc.

It's more complicated than that, but it isn't difficult to create a relatively accurate 3 dimensional model of the puck in space as long as you have a few key variables. We don't need visible markers to do this, and this can be proven by the fact that Hollywood no longer requires optical technology for their motion capture.

The biggest challenge I would see is not disrupting the feel and game behavior of the puck. The players have such an acute feel for how the puck provides feedback off their blade, the boards, and even deflections. It would have a profound effect on the game if those attributes aren't preserved.
