Abstract	In augmented reality systems, the three dimensional registration technology based on artificial markers has been widely used. The registration algorithm based on artificial markers is divided into two steps: (1) marker detection and recognition, (2) estimation of camera pose. In this paper, a novel marker is designed based on projective invariants principle, such as collinearity between points and cross-ratio. Compared with the markers used in the ARToolkit, our new marker can greatly reduce the storage space of marker templates. And based on this marker, a new detection and recognition algorithm is proposed. By using the algorithm, the registration in AR system still can be successfully completed even when the marker is occluded by 62.5%, which greatly improves the robustness of the registration algorithm. The experimental results show that the marker and the algorithm posed in this paper are effective.
