At the same time it is important that synthetic elements are rendered and aligned in the scene in an accurate and visually acceptable way. In order to address these issues a real-time, robust and efficient 3D model-based tracking algorithm is proposed for a 'video see through' monocular vision system. The tracking of objects in the scene amounts to calculating the pose between the camera and the objects. Virtual objects can then be projected into the scene using the pose. Here, non-linear pose computation is formulated by means of a virtual visual servoing approach. In this context, the derivation of point-to-curve interaction matrices is given for different features including lines, circles, cylinders and spheres. A local moving edge tracker is used in order to provide real-time tracking of points normal to the object contours. A method is proposed for combining local position uncertainty and global pose uncertainty in an efficient and accurate way by propagating uncertainty. Robustness is obtained by integrating an M-estimator into the visual control law via an iteratively re-weighted least squares implementation. The method presented in this paper has been validated on several complex image sequences including outdoor environments. Results show the method to be robust to occlusion, changes in illumination and mistracking.","PeriodicalId":296266,"journal":{"name":"The Second IEEE and ACM International Symposium on Mixed and Augmented Reality, 2003.

Over the past year our research has focused on the creation of this toolkit that can be used by technologists, designers, and students alike to rapidly prototype AR applications. Current approaches to AR development involve extensive programming and content creation as well as knowledge of technical topics involving cameras, trackers, and 3D geometry. The result is that it is very difficult even for technologists to create AR experiences. Our goal was to eliminate these obstacles that prevent such users from being able to experiment with AR. The DART system is based on the Macromedia Director multimedia-programming environment, the de facto standard for multimedia content creation. DART uses the familiar Director paradigms of a score, sprites and behaviors to allow a user to visually create complex AR applications. DART also provides low-level support for the management of trackers, sensors, and camera via a Director plug-in Xtra. This demonstration will show the wide range of AR and other types of multimedia applications that can be created with DART, and visitors will have the opportunity to use DART to create their own experiences.","PeriodicalId":296266,"journal":{"name":"The Second IEEE and ACM International Symposium on Mixed and Augmented Reality, 2003.
