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.
Claims18
A system comprising:
- a helmet containing a display visible to a users' eyes;
- several image sensors in a multi-camera array that is within the helmet, said image sensors attached together rigidly in a single frame, with each aimed at a different outward facing direction, for measuring position and orientation of the frame relative to an environment by detecting markers in the environment;
- an ad hoc arrangement of fiducial marker patterns mounted in the environment;
- wherein the display shows virtual computer-generated imagery either to replace or to augment real imagery;
- and
- wherein the multi-camera array comprises multiple outwards facing cameras that cover some or all sections of a complete spherical view.
3 more elements
A system comprising:
- a collection of several image sensors attached together rigidly in a single frame, with each aimed at a different outward facing direction, for measuring position and orientation of the frame relative to an environment by detecting markers in the environment;
- and
- wherein the several image sensors are a multi-camera array that is used for the navigation of a mobile robot within an environment with markers mounted as navigation landmarks.
