  • Range detection using machine learning combined with camera focus
    Patent number: 11935258
    Abstract: A method for range detection is described. The method includes segmenting an image into one or more segmentation blobs captured by a monocular camera of an ego vehicle. The method includes focusing on pixels forming a selected segmentation blob of the one or more segment blobs. The method also includes determining a distance to the selected segmentation blob according to a focus function value of the monocular camera of the ego vehicle.

  • Systems and methods for determining a viewing direction of a user
    Patent number: 11455744
    Abstract: Vehicles and systems and methods for determining a viewing direction of a user are disclosed. In one embodiment, a system for detecting a viewing direction of a user includes a marker arranged at a fixed location, and an optical assembly. The optical assembly includes a first optical sensor arranged to view the marker, and a second optical sensor arranged to view the user. The first optical sensor detects the marker for determining a spatial location of the optical assembly with respect to the marker, and the second optical sensor detects an eye of the user for determining an eye angle of the user.
