FOOT TRACKING |
| 摘要 |
A system and method are described for tracking the location and orientation of a user's feet for an augmented reality display. A depth sensor generates a depth map of a scene within the field of view of the depth sensor, the field of view containing at least a portion of the user. A processor is configured to identify a portion of the depth map as a candidate object for foot tracking, determine a central skeleton representation of the identified portion, determine a location of a toe of the user's foot and a location of an ankle of the user's foot, based on the central skeleton representation, and calculate an orientation of the user's foot based on the determine locations of the toe and the ankle. |

1. A system for tracking the location and orientation of a user's feet, comprising:
a depth sensor for generating a depth map of a scene within the field of view of the depth sensor, the field of view containing at least a portion of the user; and a processor, configured to:
identify a portion of the depth map as a candidate object for foot tracking;determine a central skeleton representation of the identified portion;determine a location of a toe of the user's foot and a location of an ankle of the user's foot, based on the central skeleton representation; andcalculate an orientation of the user's foot based on the determine locations of the toe and the ankle. |
