Fully automated and stable registration for augmented reality applications 完全自动化和稳定的注册增强现实应用程序

{"title":"Fully automated and stable registration for augmented reality applications","authors":"V. Lepetit, L. Vacchetti, D. Thalmann, P. Fua","doi":"10.1109/ISMAR.2003.1240692","DOIUrl":"https://doi.org/10.1109/ISMAR.2003.1240692","url":null,"abstract":"We present a fully automated approach to camera registration for augmented reality systems. It relies on purely passive vision techniques to solve the initialization and real-time tracking problems, given a rough CAD model of parts of the real scene. It does not require a controlled environment, for example placing markers. It handles arbitrarily complex models, occlusions, large camera displacements and drastic aspect changes. This is made possible by two major contributions: the first one is a fast recognition method that detects the known part of the scene, registers the camera with respect to it, and initializes a real-time tracker, which is the second contribution. Our tracker eliminates drift and jitter by merging the information from preceding frames in a traditional recursive tracking fashion with that of a very limited number of key-frames created off-line. In the rare instances where it fails, for example because of large occlusion, it detects the failure and reinvokes the initialization procedure. We present experimental results on several different kinds of objects and scenes.","PeriodicalId":296266,"journal":{"name":"The Second IEEE and ACM International Symposium on Mixed and Augmented Reality, 2003.

Immersive evaluation of virtualized soccer match at real stadium model 虚拟足球比赛在真实体育场模型下的沉浸式评价

The user sees the soccer field model in front of his/her eyes from the viewpoint through head-mounted display, while the images of players and a soccer ball are also rendered onto the display. For geometric registration between the soccer field model in the real world and the dynamic soccer scene in the rendered images, the viewpoint position of the user is computed by using only natural feature lines in the HMD camera image. Since it is difficult to strongly calibrate the HMD camera and the multiple cameras that capture the real soccer scene, we employ projective geometry for the registration and the rendering. For demonstrating the efficacy of the proposed system, video images of soccer matches taken at real stadium are rendered onto the HMD camera images of a tabletop stadium model. This is a completely new challenge to apply augmented reality to a dynamic event in a large-space.","PeriodicalId":296266,"journal":{"name":"The Second IEEE and ACM International Symposium on Mixed and Augmented Reality, 2003.
