Abstract

In this article, we present a technique for self-calibration of a CCD camera with constant focal distance using a planar scene. The particularity of our technique is the use of triangle equilateral which two vertices are defined from the matches detected in images taken by the camera. Using these vertices to estimate all the projection matrices which are operated with homographies between the images to estimate the intrinsic parameters of the camera. Experimental results show the robustness of our algorithms in terms of stability and convergence.
