When using width to approximate distance, the width gets smaller at an angle, decreasing the accuracy. Yardstick) that you hold up in the video frame, or markings on the ground a known distance apart. Distance (cm/inches/etc.) =( known width * focal length) / pixel width.

Instead of measuring the distance using stereo vision with two cameras, i want to do it using a single camera. You can put camera almost straight to the item, (considering item and camera in same room or at least such that you can put them in. Possible but you should know several things. Say you know hight of object h, and you need to find distance d from camera.
