Capturing the Heat of the Sports Moment

It looks like television has discovered thermal imaging technology. Last post we reported on how NBC News used a thermal camera to illustrate how much heat can escape from even the warmest winter clothing during the “Polar Vortex”. Well, on February 2, also known as Super Bowl Sunday, Fox Sports hopped  on board the thermal  imaging train.

Thermal Imaging Cameras At Super Bowl XLVIII
 In addition to the 79 cameras that brought viewers action on the field, they installed  one more, a high-definition, military grade thermal imaging camera to demonstrate just how much body heat players were losing to the field, and how wind chill affected their flexibility, range of motion, and stamina.

IR Cameras at The World Series
Super Bowl XLVIII was not the first time Fox Sports has called in thermal imaging. Last year, during the World Series, they also used  the technology to see temperatures in warm weather. IR cameras caught the heat of the friction generated when bat collides with ball, or ball with a player or his protective gear. 

The way Fox set up the cameras – one on each side of home plate to cover right-handed, as well as left-handed batters, plus one in the front, it’s not a stretch of the imagination to see how thermal imaging might pick up things an umpire’s vision could miss. For instance, whether the pitch that almost hit the batter's arm wasn't an almost at all. Friction is friction and the camera would pick it up. So, might thermal imaging be part of  the instant replay of the future?
Take a look at this sequence of pictures capturing Adrian Beltre "striking out."  When it careened toward third base, both the umpire and Fox announcer Joe Buck agreed it was a strike. But watch the IR friction-heated ball as it leaves the bat. 







 Was it a strike or did he foul it off his foot?

Thermal Cameras at the Daytona 500

It certainly would seem that when Fox latches on to a technology it likes, it spreads the wealth. The network first brought thermal imaging cameras to NASCAR races in 2011 at the Daytona 500 with the intention of illustrating that the heat from the engines of a pack of cars  forces the cars behind to back off a bit lest their engines overheat.

But let's here it in their own words as found in their Daytona 500 on Fox Broadcast Guide

Infrared Cam
Introduced in 2011 during Fox Sports Coverage of the 53rd Daytona 500, the network unveiled an infrared cam , a special camera designed to register variations in the heat signature of objects in its line of site. A unique feature during the race-cast demonstrates extreme temperatures that develop during typical racing conditions. Additionally, the Fox Sports infrared camera can reveal  the on-track grooves cars are using, as well as the difference between tires about to be changed compared to fresh replacements.






IR Cameras and Security

But there’s a time for fun and games and a time for safety and security, and this is where IR cameras come in to their own. Since they rely on heat rather than light they are perfect for monitoring dark areas and serve as a perfect companion to your conventional IP camera surveillance system.

Let's pause for a review.

The Electromagnetic Spectrum

Not all energy in the electromagnetic spectrum is visible to the human eye, only visible light. Light is actually energy, and although all light travels at the same speed, 186,000 miles per second, wavelengths and frequencies differ, accounting for the different levels of energy in each of the seven divisions of the spectrum.
Visible light is but a small portion of the entire spectrum, radiating about midpoint between Gamma Rays , X-rays, and Ultra-Violet light, all having shorter wavelengths and  longer frequencies. On the other side we have Infrared light, Microwaves, and Radio waves all with increasingly longer wavelengths and shorter frequencies.  Infra-red’s longer  wavelengths and  shorter frequencies lack energy sufficient to stimulate the cones in our eyes, responsible for processing visible light.

A conventional IP cameras is similar to the human eye. Its lens works only with visible light, capturing and focusing it on the image sensor which processes a digital image  But an Infrared camera is able to detect heat or thermal energy, convert it to an electronic signal and process it into a thermal image that  shows a range of temperatures. And it bears mentioning that everything on the planet gives off a degree of heat.

An  IR illuminator is used in conjunction with infra-red cameras and serves a dual purpose. It floods the dark area with sufficient infra-red light needed by the camera’s IR len and IR sensor, and thanks to IR light's invisibility as far as the human eye is concerned, allows surveillance monitoring operations to remain covert.
