....and acts to reduce the effects of outlier data introduced in the tracking process. Real time 3D tracking. The most common geometric features used in pose computation which are suitable for AR applications include indoor fiducial marker based [3, 18, 24, 29, 31] and outdoor fiducial marker based [30], the latter shows how the size of the marker contributes to robustness and ease of use. In the related computer vision literature geometric primitives considered for the estimation are often points [13, 7] segments [9] lines [19] contours or points on the contours [20, 23, 10] conics [25, 6] ....

....their accuracy. The main drawback is that they may be subject to local minima and, worse, divergence. Let us note that other approaches to on line augmented reality do not rely on pose estimation but on relative camera motion [5] planar homography estimation [27] or optical flow based techniques [30]. These methods have been shown to work in real time and in outdoor environments, however, they are restricted to planar surfaces which may be problematic in complex environments. Statistically robust tracking. To handle occlusion, changes in illumination and misstracking a statistically robust ....

....and working range of such devices is insufficient for most AR applications. Research is now focussing on computer vision based methods. Currently, the most successful ones track optical markers in indoor demonstrations, using video input from a mobile camera to determine the user s position [12, 16, 18]. Yet, marker based approaches are unlikely to be extensible to AR scenarios requiring users to operate in very large environments, e.g. a big industrial plant. New approaches are now exploring vision based approaches which track naturally occurring landmarks in the scene [19, 16] thus getting ....

....position [12, 16, 18] Yet, marker based approaches are unlikely to be extensible to AR scenarios requiring users to operate in very large environments, e.g. a big industrial plant. New approaches are now exploring vision based approaches which track naturally occurring landmarks in the scene [19, 16], thus getting by without requiring major modifications of the environment. But such systems require exponentially growing computing power when supplied with increasing numbers of natural features to be tracked. The initial question where am I requires that a set of currently seen landmark ....

....degrees of freedom (6DOF) tracking require ments for these forms of applications must be addressed. We require a low cost, moderately accurate 6DOF tracking system. T rac king is required for indoor and outdoor environments oer large areas, for example our usual testing environment is our campus [7]. GPS positional error has a less noticeable effect for the registration of augmented realit y information at distance, but xe need to address positional error when registering augmented information at close distances ( 50 m) Such a tracking system could be used for other applications, such as ....
