System and Method for Determination of 3D Pose in a Vehicle

A computer-implemented method for estimating a three-dimensional (3D) pose of a vehicle occupant, the method comprising:

• capturing, by a camera, an image of an interior cabin of a vehicle;
• utilizing a model to detect relative poses from the captured image, along with per-joint root/person-relative depth values, and output a pose classification;
• and
• mapping the relative poses to absolute poses, by computing an absolute depth/location of a body joint of the vehicle occupant for each classified pose, based on a known dimension in the interior cabin relative to the camera.

A system for estimating a three-dimensional (3D) pose of a vehicle occupant, the system comprising:

• an image sensor configured to capture at least one two-dimensional (2D) image of a vehicle cabin interior with a field of view that includes at least one occupant;
• and
• at least one processor configured to:
• detect and classify a relative pose of an occupant from the captured at least one 2D image,
• determine an absolute depth location of a joint of the occupant by anchoring the joint to a root plane, wherein the root plane is computed relative to a seating plane defined within a 3D space of the vehicle cabin interior, and
• estimate the classified pose in the 3D space based on the relative pose and the absolute depth location.
