ACCURATE POSITIONING OF AUGMENTED REALITY CONTENT

摘要

The present disclosure describes a multilevel system for accurately positioning Augmented Reality (AR) content within a coordinate system such as the WGS84 (World Geodetic System 84). AR content is tethered to Trackables. As the system is used, each mobile devices calculates and compares relative positioning data between Trackables. As measurements are made between Trackables, the system connects and groups the Trackables hierarchically. As additional measurements are made of Trackables in a group, the relative position data is improved using statistical methods. The present disclosure further describes a method for accurately associating AR content with physical location(s). The method uses trackable features of the environment and GPS coordinates to accurately position the AR content. Using information regarding the relative positions of the trackable features, gathered from user devices, the method further improves the accuracy of the position of the AR content over time.
