KINEMATIC INTERACTION SYSTEM WITH IMPROVED POSE TRACKING

Title:

KINEMATIC INTERACTION SYSTEM WITH IMPROVED POSE TRACKING

Document Type and Number:

WIPO Patent Application WO/2021/212411

Kind Code:

A1

Abstract:

Techniques are disclosed for providing improved pose tracking of a subject using a 2D camera and generating a 3D image that recreates the pose of the subject. A 3D skeleton map is estimated from a 2D skeleton map of the subject using, for example, a neural network. A template 3D skeleton map is accessed or generated having bone segments that have lengths set using, for instance, anthropometry statistics based on a given height of the template 3D skeleton map. An improved 3D skeleton map is then produced by at least retargeting one or more of the plurality of bone segments of the estimated 3D skeleton map to more closely match the corresponding template bone segments of the template 3D skeleton map. The improved 3D skeleton map can then be animated in various ways (e.g., using various skins or graphics) to track corresponding movements of the subject.
