Human tracking system
First Claim
Patent Images
1. A computer-implemented method for tracking a physical target comprising:
- receiving a depth image that captures the physical target in a physical space;
determining a first point based at least in part on an offset from a known point that corresponds to the physical target;
determining a second point that corresponds to an average location of a limb of the physical target;
determining a direction to search based on a line formed between the first point and the second point; and
determining a third point of the limb based on the direction to search and depth values of the depth image.

Abstract
An image such as a depth image of a scene may be received, observed, or captured by a device. A grid of voxels may then be generated based on the depth image such that the depth image may be downsampled. A background included in the grid of voxels may also be removed to isolate one or more voxels associated with a foreground object such as a human target. A location or position of one or more extremities of the isolated human target may be determined and a model may be adjusted based on the location or position of the one or more extremities.

11. A system, comprising:
a memory bearing instructions that, upon execution by a processor, cause the system at least to; receive a depth image that captures a physical target in a physical space; determine a first point based at least in part on an offset from a known point that corresponds to the physical target; determine a second point that corresponds to an average location of a limb of the physical target; determine a direction to search based on a line formed between the first point and the second point; and determine a third point of the limb based on the direction to search and depth values of the depth image. - View Dependent Claims (12, 13, 14, 15)

16. A computer-readable storage device bearing computer-executable instructions that, when executed on a computer, cause the computer to perform operations comprising:
-
receiving a depth image that captures a physical target in a physical space; determining a first point based at least in part on an offset from a known point that corresponds to the physical target; determining a second point that corresponds to an average location of a limb of the physical target; determining a direction to search based on a line formed between the first point and the second point; and determining a third point of the limb based on the direction to search and depth values of the depth image. - View Dependent Claims (17, 18, 19, 20)
