Abstract:
A system for accurately positioning augmented reality (AR) content within a coordinate system such as the World Geodetic System (WGS) may include AR content tethered to trackable physical features. As the system is used by mobile computing devices, each mobile device may calculate and compare relative positioning data between the trackable features. The system may connect and group the trackable features hierarchically, as measurements are obtained. As additional measurements are made of the trackable features in a group, the relative position data may be improved, e.g., using statistical methods.

Claim (Index 1):
A computer-implemented method for accurately locating augmented reality (AR) content, the method comprising:\n measuring, using one or more sensors of a computing device, a first six-degree-of-freedom (DOF) vector between a first vantage point of the computing device and a first trackable feature in a first sensor range of the computing device; measuring, using the one or more sensors of the computing device, a second six-DOF vector between the first vantage point of the computing device and a second trackable feature in a second sensor range of the computing device; estimating, based on the first vector and the second vector, using a processor of the computing device, a third six-DOF vector between the first trackable feature and the second trackable feature; storing the estimated third vector in a data store in association with the first trackable feature and the second trackable feature, such that the estimated third vector represents a spatial relationship between the first trackable feature and the second trackable feature; determining, within a common spatial coordinate system, a first set of spatial coordinates for the first trackable feature and a second set of spatial coordinates for the second trackable feature; storing, in the data store, the first set of spatial coordinates associated with the first trackable feature and the second set of spatial coordinates associated with the second trackable feature, such that the first and second sets of spatial coordinates represent respective locations of the first and second trackable features within the common coordinate system; wherein the data store includes a fourth six-DOF vector representing a spatial relationship and an orientation of an AR content item relative to the first trackable feature; associating the first trackable feature and the second trackable feature with a first group of trackable features in the data store, each trackable feature in the first group having a position and orientation defined with respect to a first coordinate system; measuring, using the computing device, a fifth six-DOF vector between the first trackable feature and a third trackable feature associated with a second group of trackable features in the data store, each trackable feature in the second group having a position and orientation defined with respect to a second coordinate system; and calculating a positional offset and an orientation offset between the first group and the second group based on the fifth six-DOF vector.
