OCCUPANT HEAD POSITION IN VEHICLE

A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive a first image frame from a first camera of a vehicle and a second image frame from a second camera of the vehicle, identify a common point in the first image frame and the second image frame, determine a projected position of the common point projected onto a plane based on the first image frame and the second image frame, and determine a position of the common point based on the projected position. A first optical axis defined by the first camera and a second optical axis defined by the second camera are in the plane.
