Tracking multiple augmented reality devices

Abstract

The present application is directed to device synchronization and alignment in augmented reality. Two electronic devices create two maps of a scene according to two different coordinate systems. And the first electronic equipment determines the equipment attitude of the second electronic equipment in the first coordinate system of the first electronic equipment. The equipment attitude is used for determining a transformation relation between the two coordinate systems. The first electronic device obtains a second object pose measured in a second coordinate system of the second electronic device and used to render the object in a second map of the second electronic device. And converting the second object attitude into the first object attitude in the first coordinate system based on the transformation relation. The objects are simultaneously rendered in first and second maps of the first and second electronic devices based on the first and second object poses, respectively.
