Embodiment Construction

[0010] A depth image analysis system, such as a 3D vision gaming system, may include a depth camera capable of viewing one or more players. As the depth camera captures images of the player within the observed scene, those images may be interpreted and modeled with one or more virtual skeletons. As described in more detail below, a virtual skeleton can be used as an input for controlling a three-dimensional virtual game world, such as a game of god. In other words, the depth camera can observe and model a human being performing gestures designed to control all aspects of the three-dimensional virtual game world, and the human target can be modeled with a virtual skeleton that God Games can interpret as different controls. In this way, humans can control a three-dimensional virtual game world using only gestures, thereby avoiding conventional keyboards, mice, track pads, and other controllers.

Abstract

The invention describes a skeletal control of a three-dimensional virtual world. The virtual skeleton includes a plurality of joints and provides a machine readable representation of a human target observed with a three-dimensional depth camera. A relative position of a hand joint of the virtual skeleton is translated as a gestured control, and a three-dimensional virtual world is controlled responsive to the gestured control.

Description

technical field [0001] The present invention relates to image capture and processing, and more particularly to skeletal control. Background technique [0002] While camera technology allows images of humans to be recorded, it can be difficult for computers to use such images to accurately assess how humans move through the images. Recently, technology has advanced to explain some aspects of human movement with the help of special cameras and tracking tags. For example, actors can be carefully decorated with several tracking tags (such as retroreflectors), which can be tracked by several cameras from several different positions. Triangulation can then be used to calculate the three-dimensional position of each reflector. Because the tags are carefully placed on the actor, and the relative position of each tag to the corresponding part of the actor's body is known, triangulation of the tag's position can be used to infer the position of the actor's body. However, this techn...
