Image-based geometric measurement is getting more attention in machine vision field due to its contact-less and low-cost characteristics. Here the measurement of single image with the rectangular structure is studied, in which only one side length of the rectangle is known, and the coordinates of points in the measured plane are obtained. The intrinsic parameters of the camera are calibrated firstly by using the three vanishing points of mutually orthogonal directions. Then the homography between the image plane and the model plane which the rectangle structure belongs to is derived, and the plane measurement method of the latter is described in details. Furthermore, the measurement experiment is done with the single image taken by the camera, and the validity of the proposed method is verified by comparing with real data.
