Kind Code:
A1
Abstract:
The present application relates to the field of intelligent driving, and discloses a gaze calibration method and apparatus, a device, a computer-readable storage medium, a system, and a vehicle. In the present application, an eye three-dimensional position of a user is obtained by means of a first image comprising eyes of the user, a gaze point three-dimensional position of the user is obtained by means of a calibration position on a display screen or a second image comprising a scene outside a vehicle as seen by the user, and a high-accuracy second gaze direction is obtained according to the eye three-dimensional position and gaze point three-dimensional position of the user, such that the accuracy of gaze estimation of the user is effectively improved, and the present application may be suitable for a cockpit scene. In addition, in the application, an optimization sample comprising the second gaze direction of the user and the first image thereof is also used to optimize a gaze tracking model by means of a few‑shot learning method, such that the accuracy of gaze estimation of the gaze tracking model for a specific user is improved, and a gaze tracking model having high accuracy for the specific user can be obtained.
