Nvidia patents 3D camera system to measure passengers in vehicles

Patent drawing
Patent drawing from the official filing.

Nvidia describes a system that uses a camera to create a 3D model of a person inside a vehicle. It combines a standard image with depth information to estimate the passenger's size, pose, and potential weight.

Why it mattersThis technology could allow cars to automatically adjust seats or safety features based on the driver's physical size without using manual inputs.

In the filing’s own words

In various examples, image-based three-dimensional occupant assessment for in-cabin monitoring systems and applications are provided. An evaluation function may determine a 3D representation of an occupant of a machine by evaluating sensor data comprising an image frame from an optical image sensor. The 3D representation may comprise at least one characteristic representative of a size of the occupant, (e.g., a 3D pose and/or 3D shape), which may be used to derive other characteristics such as, but not limited to weight, height, and/or age. A first processing path may generate a representation of one or more features corresponding to at least a portion of the occupant based on optical image data, and a second processing path may determine a depth corresponding to the one or more features based on depth data derived from the optical image data and ground truth depth data corresponding to the interior of the machine.

What exactly they claim (claim 1)

1. A system comprising: one or more processing units comprising circuitry to: detect one or more features representing at least a portion of an occupant of a machine based at least on two-dimensional optical image data; determine a depth corresponding to the one or more features based at least on the optical image data and a ground truth cabin depth image corresponding to an interior of the machine; generate a three-dimensional representation of the occupant based at least on the one or more features and the depth of the one or more features, wherein the three-dimensional representation comprises at least one characteristic representative of a size of the occupant; and control at least one operation of the machine based at least on the at least one characteristic.
