1. A method, comprising:
- receiving a first and a second frame of depth data, by a computer, the first and the second frames of depth data having been captured from a camera component;
scanning, by the computer, a human target in the first and the second frames of depth data;
calculating, by the computer, a first tilt angle of the human target relative to the camera component based on the scanned human target in the first frame of depth data;
calculating, by the computer, a second tilt angle of the human target relative to the camera component based on the scanned human target in the second frame of depth data; and
storing, by the computer, a combined tilt angle for the human target, the combined tilt angle comprising a combination of the first tilt angle and the second tilt angle.

Abstract
A depth image of a scene may be received, observed, or captured by a device. A human target in the depth image may then be scanned for one or more body parts such as shoulders, hips, knees, or the like. A tilt angle may then be calculated based on the body parts. For example, a first portion of pixels associated with an upper body part such as the shoulders and a second portion of pixels associated with a lower body part such as a midpoint between the hips and knees may be selected. The tilt angle may then be calculated using the first and second portions of pixels.

9. A computer-readable storage device having stored thereon computer executable instructions for detecting a tilt, that, when executed on a computer, cause the computer to perform operations comprising:
-
receiving a first and a second frame of depth data the first and the second frames of depth data having been captured from a camera component; scanning a human target in the first and the second frames of depth data; calculating a first tilt angle of the human target relative to the camera component based on the scanned human target in the first frame of depth data; calculating a second tilt angle of the human target relative to the camera component based on the scanned human target in the second frame of depth data; and storing a combined tilt angle for the human target, the combined tilt angle comprising a combination of the first tilt angle and the second tilt angle. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for detecting a tilt, the system comprising:
a memory bearing instructions that, upon execution by a processor, cause the system to at least; receive a first and a second frame of depth data the first and the second frames of depth data having been captured from a camera component; scan a human target in the first and the second frames of depth data; calculate a first tilt angle of the human target relative to the camera component based on the scanned human target in the first frame of depth data; calculate a second tilt angle of the human target relative to the camera component based on the scanned human target in the second frame of depth data; and store a combined tilt angle for the human target, the combined tilt angle comprising a combination of the first tilt angle and the second tilt angle. - View Dependent Claims (18, 19, 20)
