Problems solved by technology

[0006] Although there may be some instances of real-world objects with fiducial markers, these markers are difficult to identify
Identifying fiducial markers is especially troublesome at medium and long distances
Furthermore, traditional fiducial markers cannot store large amounts of data that can be converted to or used to generate computer-generated content in augmented reality applications

Abstract

Fiducial markers for augmented reality are provided. A fiducial marker can be located on an object in the environment and includes retroreflectors that reflect light back towards the source of the light. A portion of the fiducial marker is masked or obscured to form a pattern in the fiducial marker including a reflective portion and a less or non-reflective portion. The pattern of the reflective portion and the less or non-reflective portion stores data that can be read by a reading device and used to generate computer-generated content that is included in an augmented image.

Description

Background technique [0001] Augmented reality generally describes views or images of real-world environments that have been enhanced with computer-generated content. Combining real-world imagery with computer-generated content has proven useful in many different applications. Advertising, navigation, military, travel, education, sports and entertainment are examples of areas where augmented reality could be used. [0002] Merging images of real-world environments with computer-generated content results in enhanced images. However, the successful merging of real-world images with computer-generated content often depends on how well real-world images are recognized. For example, successfully enhancing an image of a monument may depend on whether the device displaying the image of the monument recognizes the monument. More specifically, incorporation of computer-generated content (eg, monument's name, location, founder, etc.) may depend on whether the monument is identified in...
