Abstract:
Methods, systems, and devices are described for determining an orientation of a mobile device. One method includes 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 an orientation of the mobile device based at least in part on the first angle, the second angle, and the third angle.
