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.
Claims30
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.
An apparatus for determining an orientation of a mobile device, comprising:
- means for capturing, at the mobile device, an image of at least one illuminated object defining an illuminated reference axis;
- means for determining a first angle between the illuminated reference axis and a device reference axis of the mobile device;
- means for determining a second angle between the illuminated reference axis and a common reference axis;
- means for estimating a third angle between the device reference axis and the common reference axis;
- and
- means for determining the orientation of the mobile device based at least in part on the first angle, the second angle, and the third angle.
An apparatus for determining an orientation of a mobile device, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- capture, at a mobile device, an image of at least one illuminated object defining an illuminated reference axis;
- determine a first angle between the illuminated reference axis and a device reference axis of the mobile device;
- determine a second angle between the illuminated reference axis and a common reference axis;
- estimate a third angle between the device reference axis and the common reference axis;
- and
- determine the orientation of the mobile device based at least in part on the first angle, the second angle, and the third angle.
A computer program product for determining an orientation of a mobile device, the computer program product comprising a non-transitory computer-readable medium storing instructions executable by a processor to cause the mobile device to:
- capture, at a mobile device, an image of at least one illuminated object defining an illuminated reference axis;
- determine a first angle between the illuminated reference axis and a device reference axis of the mobile device;
- determine a second angle between the illuminated reference axis and a common reference axis;
- estimate a third angle between the device reference axis and the common reference axis;
- and
- determine the orientation of the mobile device based at least in part on the first angle, the second angle, and the third angle.
