Title:
ENHANCED TECHNIQUES FOR REAL-TIME MULTI-PERSON THREE-DIMENSIONAL POSE TRACKING USING A SINGLE CAMERA
Document Type and Number:
WIPO Patent Application WO/2023/102873
Kind Code:
A1
Abstract:
This disclosure describes systems, methods, and devices related to real-time multi-person three-dimensional pose tracking using a single camera. A method may include receiving, by a device, two-dimensional image data from a camera, the two-dimensional image data representing a first person and a second person; generating, based on the two-dimensional image data, two-dimensional positions of body parts represented by the first person; generating, using a deep neural network, based on the two-dimensional positions, a three-dimensional pose regression of the body parts represented by the first person; identifying, based on the two-dimensional positions and the three-dimensional pose regression, contact between a ground plane and a foot of the first person; generating an absolute three-dimensional position of the contact between the ground plane and the foot of the first person; generating, based on the absolute three-dimensional position, a three-dimensional pose of the body parts represented by the first person.
