%0 Journal Article %T Tracking Chessboard Corners Using Projective Transformation for Augmented Reality %A Salim Malek %A Nadia Zenati-Henda %A M.Belhocine %A Samir Benbelkacem %J International Journal of Image Processing %D 2011 %I Computer Science Journals %X Augmented reality has been a topic of intense research for several years for many applications. Itconsists of inserting a virtual object into a real scene. The virtual object must be accuratelypositioned in a desired place. Some measurements (calibration) are thus required and a set ofcorrespondences between points on the calibration target and the camera images must be found.In this paper, we present a tracking technique based on both detection of Chessboard cornersand a least squares method; the objective is to estimate the perspective transformation matrix forthe current view of the camera. This technique does not require any information or computation ofthe camera parameters; it can used in real time without any initialization and the user can changethe camera focal without any fear of losing alignment between real and virtual object. %K Pinhole Model %K Least Squares Method %K Augmented Reality %K Chessboard Corners Detection. %U http://cscjournals.org/csc/manuscript/Journals/IJIP/volume5/Issue1/IJIP-314.pdf
