Abstract
Fiducial markers are printed patterns detected by algorithms in imagery from image sensors for applications such as automated processes and augmented reality graphics. The present invention sets forth extensions and improvements to detection technology to achieve improved performance, and discloses applications of fiducial markers including multi-camera systems, remote control devices, augmented reality applications for mobile devices, helmet tracking, and weather stations.
Claims23
An augmented reality system comprised of:
- capture means for capturing at least one video or still image, said capture means having a display screen;
- fiducial marker patterns located on one or more objects within view of the capture means;
- recognition means for recognizing said fiducial markers in the at least one video or still image;
- calculation means for calculating a mathematical transform between the display screen of the capture means and arbitrary world coordinates of the fiducial marker patterns;
- graphic drawing means for placing overlay drawings and graphics on the display screen;
- transmission means for transmitting the at least one video or still image to a remote location;
- and
- receiver means for receiving other overlay drawings and graphics from the remote location;
- wherein the mathematical transform is a ‘homography’ matrix, ‘projection matrix’, or a representation of euclidean rotation and translation.

An augmented reality system comprised of:
- fiducial marker patterns located on one or more objects or locations of interest at a remote location;
- capture means for capturing at least one video or still image of the fiducial marker patterns, said capture means having a display;
- recognition means for recognizing said fiducial markers in the at least one video or still image;
- transmission means for transmitting the recognized fiducial marker patterns to a central location;
- and
- receiver means for receiving visually displayed information associated with the remote location from the central location;
- wherein the visually displayed information is shown on the display;
- wherein the visually displayed information includes information from a security camera display or information pertaining to an industrial automation system.
