Now days Hawk Eye technology mostly uses in sports like cricket, tennis, snooker etc. If we think sports like tennis or cricket, this technology use to identify the route of the ball, fault service or not (Tennis), LBW (cricket) like facts. So if umpire has done any mistake Hawk Eye technology solve the problem.  The bunch of Engineers in Rock Manor Research Institute in United Kingdom is the founders of this technology. After that this Hawk-Eye becomes popular in the world. Actually Hawk-Eye is just a commercial name of this technology. Lets we look at how this technology works?

                                                                I’ll explain it by using sports (Tennis or cricket). First the technical team of Hawk Eye create a “3 Dimensional Model” of the play ground in the computer. Then they setup 4 high speed cameras around the ground (Actual Play ground) (In cricket it covers the pitch, in tennis it covers the court) and mark that actual camera positions in 3 Dimensional Model also. The important thing is these high speed cameras do not change its positions throughout the match (Else all calculation will go wrong).
