Why can I get the right position of the robot?

[GoogleCodeExporter]

What steps will reproduce the problem?
1.only operate as the rules 

What is the expected output? What do you see instead?
I expected an exact position of some robot.
But I get the  projected position of the robot.

What version of the product are you using? On what operating system?
r194 ubuntu 9.10

Please provide any additional information below.

If the position which I get  is exactly the projected position,why does the 
SSL-Vision need a robot Height?
Can The SSL-Vision tell me the var "z" of the struct of SSL_DetectionBall as 
below?

ps:
message SSL_DetectionBall {
  required float  confidence = 1;
  optional uint32 area       = 2;
  required float  x          = 3;
  required float  y          = 4;
  optional float  z          = 5;
  required float  pixel_x    = 6;
  required float  pixel_y    = 7;
}

well,I mistook the rules.
Now ,can you tell me how I can get the height of the ball when the ball is 
flying.
As usual,I get the number "Nan".

Thank you~

ssl-vision does not (yet) provide the ball height for chip kicks. One possible 
approach to tracking chip kicks, which you could implement in your system's 
tracker is described in the following paper:
