If you have the Computer Vision System Toolbox, see this link on camera calibration:

With one camera, you may be able to compute the distance if you have a calibrated camera, and you know the actual size of the object. If you do not know the size of the object, then you would need a calibrated stereo camera, or an RGB-D camera.
