OBJECT ORIENTATION ESTIMATION
First Claim
Patent Images
1. A method performed by a computing device, the method comprising:
- determining a first estimate of object orientation using a first technique and image data;
determining a second estimate of the object orientation using a second technique and the image data;
correcting the first estimate using the second estimate to generate a corrected object orientation estimate; and
outputting the corrected object orientation estimate.

Abstract
The description relates to estimating object orientation. One example includes determining a first estimate of object orientation using a first technique and image data. In this example, a second estimate of the object orientation can be determined using a second technique and the image data. The first estimate can be corrected with the second estimate to generate a corrected object orientation estimate which can be output.

13. A computer-executable memory device or storage device storing computer-executable instructions that, when executed by one or more processing devices, cause the one or more processing devices to perform acts comprising:
-
determining landmarks of an object; determining a geometric model associated with the object; using the geometric model, determining a first rotation angle estimate of the object relative to an axis of rotation using a first technique; using the landmarks, determining a second rotation angle estimate of the object relative to the axis of rotation using a second technique; correcting the first rotation angle estimate using the second rotation angle estimate to generate a corrected rotation angle estimate; determining other estimates of other rotation angles of the object relative to other axes of rotation of the object; and determining an object orientation from the corrected rotation angle estimate and the other estimates of the other rotation angles. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system, comprising:
-
a processing device; and a storage device storing computer-executable instructions which, when executed by the processing device, cause the processing device to; determine a facial plane and facial landmarks of a head of a user from an image of the user; estimate one or more head rotation angles of the user using a first technique and the facial plane; and correct at least one of the head rotation angles of the user using a second technique and the facial landmarks. - View Dependent Claims (20, 21)
