Abstract This paper describes a methodformeasuringthe ,intrinsicparameters of a camera. If aspect ratio is already known, the method requires two images of a plane; if aspect ratio is not known, the method requires three images of the plane. (Equivalently, one image of n planes could be used instead ofn images of one plane). The plane must be marked with four points in known configuration.

    • ...How can we enforce this constraint? Should a separate variable for the position of the horizon be introduced? It turns out [21] that under our assumption about internal camera parameters (square pixels and known principal point) this is not necessary...

    • ...After that, Beardsley et al. [28] developed a method for measuring intrinsic parameters using vanishing points from one image of model planes, and Cipolla et al. [29] proposed a method to compute both intrinsic and extrinsic parameters from three vanishing points and two reference points from two views...

    • ...For example, in [4], [6], [7], [8], [9], [11], [20], [31], [32], vanishing points (VPs) and vanishing lines have been used to compute intrinsic and rotation parameters in a first stage, while the remaining parameters can be computed by solving a system with reduced degrees of freedom in a second stage...
