Hi,To find the an object distance (working distance) in an image, I can do this
object distance = focal length*((1/magnification) + 1)

Currently I do not see the relation between your question and Matlab. Because this is a Matlab forum, your problem might be off-topic.

hi, first Your question is not clear? second, on a single image you can not extract object distance,=> you need stereovision, or other techniques like depth from focus or special cameras( Time Of Flight) I suppose you refer to the thin lens equation but this is only for an object in focus

@Thomas: Please read the text of the posted link again. The term "camera distance" is defined and in the previous chapter you find "image distance" also.
