This is one of those things that sounds really dewy-eyed in theory but end up being incredibly complicated when you in reality attempt to do it ! The organisation that ESPN , FOX , and others use to paint the logical argument is called"1st and Ten"and is created by a companionship calledSportvision .
The simplest description of this system is : The first - down line of business is drawn on the sphere with a computer so that viewers seeing the biz on goggle box can see the line as though it were painted on the field . Here are some of the problems that have to be solved in order for this system to work :
There are probably several other complication , as well … It ’s a tough problem !
To solve these problems , the Jehovah of the first and Ten system commingle ironware and software system . First , eachcameramust have a very sensitiveencoderattached to it that can read the camera ’s slant , tilt , zoom and so on , and send that entropy to the system . The system must also have a detailed3 - 500 modelof the field so that it knows where each one thousand line is . By integrating the joust , genus Pan and zoom selective information with the 3 - D model , the system can set about to bet where the line should go . Then the system usescolor palettesfor the field and the players / referees / ball to recognize , pixel by pixel , whether it is calculate at the field or something else . This mode , only the field gets painted .
accord to the Sportvision internet site , all of this calculation requires a great deal of equipment : " There are eight computers ( four SGIs and onePCand three special purpose data point acquisition computers ) , three solidification of limited encoders and abundant wiring dedicated to generating the practical first down line in TV format . " Who would have intend …
