In vision-based augmented reality systems, the relation between the real and virtual worlds needs to be estimated to perform the registration of virtual objects. This paper suggests a vision-based registration method for video see-through augmented reality systems using binocular cameras which increases the quality of the registration performed using three points of a known marker. The originality of this work is the use of both monocular vision-based and stereoscopic vision-based techniques in order to complete the registration. Also, a method that performs a correction of the 2D positions in the images of the marker points is proposed. The correction improves the registration stability and accuracy of the system. The stability of the registration obtained with the proposed registration method combined or not with the correction method is compared to the registration obtained with standard stereoscopic registration.
