Determining an orientation of a mobile device
First Claim
1. A method for determining an orientation of a mobile device, comprising:
- capturing, at the mobile device, an image of at least one illuminated object defining an illuminated reference axis;
determining a first angle between the illuminated reference axis and a device reference axis of the mobile device;
determining a second angle between the illuminated reference axis and a common reference axis;
estimating a third angle between the device reference axis and the common reference axis; and
determining the orientation of the mobile device based at least in part on the first angle, the second angle, and the third angle.
