ABSTRACT

The inconvenient of the marker-based alternative are the sensitive to the occlusion and the environment adaptation. This work introduces a novel estimation technique to compute camera translation when a marker is partially occluded. The approach has two main advantages: 1) only one marker is necessary; and 2) it has a low computational cost. As a result of the second feature, this proposal is ideal for mobile devices. To construct the estimations, the information calculated by ARToolKit is used and no image processing and analysis is added. Our method improves the robustness with occlusions and doesn’t incorporate any extra marker.
