By calibrating the camera I was able to guess the xyz(world point) value.

But I want to match this coordinate with the robot.

Please tell me how

And are the TCP coordinates absolute?

The process for communicating between a vision system and the robot is greatly dependant on the brand of camera and the communication interface it uses. I would suggest going back to the manufacturer/supplier of the camera for further advice.
