| Problem: Together with the LANTISS (Laboratoire des nouvelles technologies de l’image, du son et de la scène, i.e. Laboratory of new image, sound and theatre technologies), the Computer Vision and Systems Laboratory is developing a tool for collaborative theatre productions. This tool involves two components: i) a real castelet, i.e. a type of miniature theatre enabling producers to work with a miniature stage and ii) a virtual castelet, which is a virtual representation of the real castelet. The virtual castelet presents the advantage of allowing several users to modify the contents of the electronic castelet from a distance, via the Internet network, and thus collaborate in the theatre production. In these situations, it is important that there be a harmonious relationship between the contents of the real castelet and those of the virtual castelet. This problem will be addressed in the present research project. |
| Motivation: This research project will be devoted to three aspects of the electronic castelet project. The first aspect involves the tracking, via 2D cameras, of objects moving around within the real castelet. The objective of this part of the project is to estimate the position and orientation of objects in a 3D Cartesian space and to transmit this information to corresponding objects in the virtual castelet. The second part of the project will be devoted to moving the objects within the virtual castelet (the objects are viewed in 3D using stereoscopic glasses) and, via a 3D interface, allow the user to move the objects within the real castelet so that their position and orientation correspond to those of the objects in the virtual world. Artificial vision will serve as an interface with the virtual world. The third aspect of this project consists in rendering the real-virtual interactions mentioned above collaborative. This implies that the virtual environment be shared by several users and that these users can work in collaboration on the theatre production via the network, while maintaining a replica of the real castelet which perfectly matches the virtual castelet. |
| Approach: The main steps of the project are the following:
1. Familiarisation with the algorithms for 3D object tracking using 2D cameras (exploitation of ARToolKit);
2. Familiarisation with 3D graphic visualisation tools in virtual environments (VTK);
3. Familiarisation with virtual environment interaction tools (spacepuck, VR glove);
4. Implementation of the algorithms for 3D tracking using 2D cameras and transfer of the position and orientation to their corresponding counterparts in the virtual world. |
