Human tracking system

摘要

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.

主权项

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.
