Method and device for synchronizing augmented reality coordinate systems

A first electronic device comprising:

• one or more processors;
• a non-transitory memory;
• and
• one or more programs, wherein the one or more programs are stored in the non-transitory memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• determining a reference location in a three-dimensional space based on a feature, wherein the feature is generated by a second electronic device;
• obtaining, for the reference location, first reference coordinates in an augmented reality coordinate system of the first electronic device and second reference coordinates in an augmented reality coordinate system of the second electronic device;
• determining a coordinate transformation based on a function of the first reference coordinates and the second reference coordinates;
• and
• synchronizing an augmented reality coordinate system of the first electronic device with an augmented reality coordinate system of the second electronic device using the coordinate transformation.

A non-transitory computer-readable medium having instructions encoded thereon which, when executed by a processor of a first electronic device, cause the processor to perform operations comprising:

• determining a reference location in a three-dimensional space based on a feature, wherein the feature is generated by a second electronic device;
• obtaining, for the reference location, first reference coordinates in an augmented reality coordinate system of the first electronic device and second reference coordinates in an augmented reality coordinate system of the second electronic device;
• determining a coordinate transformation based on a function of the first reference coordinates and the second reference coordinates;
• and
• synchronizing an augmented reality coordinate system of the first electronic device with an augmented reality coordinate system of the second electronic device using the coordinate transformation.
