Abstract
A method and system for computer assisted site navigation includes capturing an image of a scene for providing real-time image data, calibrating a camera and localizing the image by utilizing the image data and retrieved marker registration and floor-map data for providing position and orientation data, transmitting the data to a web server, utilizing the image data and information on the scene retrieved from a database for deriving an augmented view, and displaying the augmented view.
Claims13
A method for computer assisted site navigation, comprising the steps of:
- capturing an image of a scene for providing real-time image data;
- calibrating a camera and localizing said image utilizing said image data and retrieved marker registration and floor-map data for providing position and orientation data;
- transmitting said data to a web server;
- utilizing said image data and information on said scene retrieved from a database for deriving an augmented view;
- and
- displaying said augmented view.
A method for computer assisted site navigation, comprising the steps of:
- capturing an image of a scene including markers on a video camera for providing real-time image data;
- processing said image data for providing feature extraction and marker detection data;
- utilizing said feature extraction and marker detection data and stored information including marker registration and floor-maps for calibrating said camera, localizing said image, and computing coordinates for deriving position and orientation data;
- displaying said position and orientation data;
- transmitting said data to a web server;
- utilizing said image data and information on said scene retrieved from a database for deriving an augmented view;
- and
- displaying said augmented view.
