How to use Robotino camera for object tracking

edit

Hello,

In my project, I am required to use the robotino to track the movement of an object using a camera and then make the robotino follow it. How should I go about it? I am thinking the first step would be to figure out how to extract the image from the camera, then map it to some coordinate system, obtain a new image in which the object has moved and set the laserrangefinder to the new position, where the new position would be the navigation goal. Can somebody help?
