Determining coordinate frames in a dynamic environment

摘要

Embodiments are disclosed for methods and systems of distinguishing movements of features in a physical environment. For example, on a head-mounted display device, one embodiment of a method includes obtaining a representation of real-world features in two or more coordinate frames and obtaining motion data from one or more sensors external to the head-mounted display device. The method further includes distinguishing features in one coordinate frame from features in another coordinate frame based upon the motion data.

1. On a head-mounted display device, a method comprising:
obtaining via image data from a camera a representation of real-world features in two or more coordinate frames; obtaining motion data from one or more sensors external to the head-mounted display device, each sensor being associated with a corresponding coordinate frame; displaying, on a see-through display of the head-mounted display device, a first virtual object at location relative to a first real-world feature in a first coordinate frame in a field of view of the display device and a second virtual object at location relative to a second real-world feature in a second coordinate frame in the field of view of the display device; determining relative motion characteristics of the sensors based upon the motion data; distinguishing features in the first coordinate frame from features in the second coordinate frame based upon the relative motion characteristics; and updating the location of the first virtual object based upon a relative motion of the first coordinate frame and updating the location of the second virtual object based upon a relative motion of the second coordinate frame.
