| Outline of Final Research Achievements |
In this project, we developed several methods for in-situ AR system including methods for object/environment reconstruction, methods object/environment authoring, photometric registration, and so on. To actualize editable AR environment, we developed not only the methods to estimate geometric properties including shape of an object and camera position and position but also the methods to estimate optical properties including texture of an object and lighting environment. In addition, we developed user interface for editing those properties. As a result of these development, the stability of the estimation of camera position and pose or reconstruction of environment decreases with time because real environment is constantly changing. Especially optical variation is critical for the feature point tracking. Therefore we tackled to develop a feature point tracking method robust for lighting variation.
