Here’s some good news for all the fools who thought 3D TV was going to be the next big thing back in 2013. Researchers at MIT have developed a system that converts 2D video into 3D. The resulting 2D video can be played on an Oculus Rift, a Google Cardboard, or even that 3D TV sitting in the living room.
Right now, the system only works on 2D broadcasts of football, but this is merely a product of how the researchers solved this problem. The problem was first approached by looking at screencaps of the game FIFA 13. Using an analysis tool called PIX, the researchers both stored the display data and extracted the corresponding 3D map of the pitch, players, ball, and stadium. To generate 3D video of a 2D football broadcast, the system then looks at every frame of the 2D broadcast and searches for a 3D dataset that corresponds to the action on the field. This depth information is then added to the video feed, producing a 3D broadcast using only traditional 2D cameras.

The [Fédération Internationale de Football Association] is joining the growing list of professional sports that is adopting technological means in an attempt to help the human referees. After a botched call in 2010 the organization called for a system that would work day or night, with 100% accuracy and the ability to report to the Refs in less than 1 second. The applicants have been weeded out and it comes down to two systems, both of which use a piece of personal hardware we’re quite familiar with. [Fe80], who sent in the tip, recognized the TI Chronos eZ430 watch in the image above.
The two systems both use the watch as an interface, but work very differently. The first, called GoalRef, uses a sensor suspended inside the ball. This detects a magnetic field made up by the goal posts. We’d guess it’s an inductance sensor that is triggered when it passes a coil in the goal posts (we didn’t find much in the way of technical info so please do your own speculation in the comments). The second system is very familiar. It’s the Hawkeye camera system used by the APT (Tennis) in all the major tournaments.
