Measuring distance of an object using 2 stereo vision cameras

Given two cameras. I have to first detect an object using the 2 stereo vision cameras. Then I will have to calculate the distance of the object from the cameras using the camera calibration parameters. Finally I have to display the object encircled by a reactangle which says "Object 1" and also displays its distance from the camera in terms of the world units (mm here). It will be of great help if someone can give the code for the above.

Do you have the Computer Vision Sytem Toolbox? If so, use the camera calibration functionality. See the links on the right hand side of this page.
