Embodiment Construction

[0013] 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. Sometimes the player can be in positions that are difficult to explain and to accurately model with a virtual skeleton. For example, the player may turn sideways so that certain parts of the player are hidden from the depth camera, and thus may not appear in those depth images captured by the depth camera. As another example, a player's hands may be clasped together, making it difficult for the system to distinguish between left and right hands. As a result of these and other difficult scenarios, the virtual skeleton used to model the player may jitter from frame to frame, or otherwise model the player inaccurately. However, the following disclosure at least partially alleviates the ...

Abstract

The invention relates to bi-modal depth-image analysis. A depth-image analysis system calculates first mode skeletal data representing a human target in an observed scene if a portion of the human target is observed with a first set of joint positions, and calculates second mode skeletal data representing the human target in the observed scene if the portion of the human target is observed with a second set of joint positions different than the first set of joint positions. The first mode skeletal data and the second mode skeletal data have different skeletal joint constraints.

Description

technical field [0001] The present invention relates to computer applications, in particular to deep image analysis techniques. Background technique [0002] Computer technology has advanced to enable humans to interact with computers in various ways. One such interaction can occur between a human and the game system. Some game systems respond to the player's physical movement. However, player movements can be misinterpreted, resulting in an unsatisfactory gaming experience. Contents of the invention [0003] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of the i...
