A method for measuring object distance on the plane based on monocular vision

摘要

Plane measurement is an important task in image processing and computer vision. In this paper, we present a kind of plane measurement method for monocular vision, which calculates the image magnification by controlling the camera movement, the height of object and camera focal length. We can finally get the measurement results. Experimental results show that the proposed method can measure the distance more accurately. What's more, it has the advantages of high universality, simple steps and small error.
