Method for advanced imaging in augmented reality
First Claim
1. A method for using advanced image information to increase the quality of an Augmented Reality (AR) image comprising the image from a camera combined with computer-generated graphics to create an AR display, and for using a motorized camera mount for the camera in a tracking system for AR, the method comprising:
- capturing an image or view of the real world with a camera having a lens, the camera being moved by a motorized camera mount;
obtaining one or more imaging parameters of the camera and camera lens, the imaging parameters selected from the group consisting of focus, aperture, field of view, exposure time, light sensitivity setting and measured light level;
determining at least the orientation of the camera by using a computer to obtain information from the motorized camera mount;
in response to at least the camera orientation received by the computer from the motorized camera mount, using the computer to control the aim of the camera by sending control signals to the motorized camera mount to move the camera to a specified orientation, wherein the control signals cause the motorized camera mount to move the camera to the specified orientation, to thus accomplish a feedback-based camera position control system;
in response to the camera orientation received by the computer from the motorized camera mount and in response to the obtained imaging parameters, using a computer to render a graphical image representing unseen information that corresponds to the known orientation of the camera viewpoint, wherein the unseen information is rendered such that it is visually consistent with the obtained imaging parameters, and the orientation of the camera;
augmenting the image or view of the real world with the computer generated image; and
presenting the augmented image or view to the user.

Abstract
The invention is a method for displaying otherwise unseen objects and other data using augmented reality (the mixing of real view with computer generated imagery). The method uses image parameters (such as field of view, focus, aperture, and shading) that affect the real world view as captured by a camera. The camera may have a motorized camera mount that can report the position of a camera on that mount back to a computer. With knowledge of where the camera is looking and the additional image parameters, the computer can precisely overlay computer-generated imagery onto the video image produced by the camera such that the appearance of computer-generated imagery is consistent with the image of the real world. The method may be used to present to a user such items as existing weather conditions, hazards, or other data, and presents this information to the user by combining the computer generated images with the user'"'"'s real environment. These images are presented in such a way as to display relevant location and properties of the computer-generated imagery to the system user. The primary intended applications are as tools for training and monitoring of surveillance systems, disaster command and control response training and operations, and any application in which it is desired to have realistic imagery that corresponds to the real world.
