  • Patent number: 12039790
    Abstract: A method for detecting a position of a seatbelt in a vehicle includes: capturing, by a camera, a source image of an occupant in the vehicle; determining a pose of the occupant based on the source image; determining an occupant shadow based on the pose of the occupant; determining, based on the occupant shadow, a shadow overlying a region of interest (ROI) in the source image; and detecting, based on the shadow overlying the ROI, the seatbelt within the ROI. A system for detecting a position of a seatbelt is also provided. The system includes a camera and controller in communication with the camera and configured to: determine a pose of the occupant; determine an occupant shadow based on the pose of the occupant; determine, based on the occupant shadow, a shadow overlying the ROI; and detect, based on the shadow overlying the ROI, the seatbelt within the ROI.

  • Patent number: 12039789
    Abstract: A system and method for detecting seatbelt positioning includes capturing, by a camera, a near infrared (NIR) image of an occupant, applying a median filter to the NIR image to remove glints; converting the NIR image to a black-and-white image, scanning across the black-and-white (B/W) image to detect a plurality of transitions between black and white segments corresponding to stripes extending lengthwise along a length of the seatbelt, and using detections of the plurality of transitions to indicate a detection of the seatbelt. Converting the NIR image to the black-and-white image may include using a localized binary threshold to determine whether a given pixel in the B/W image should be black or white based on whether a corresponding source pixel within the NIR image is brighter than an average of nearby pixels within a predetermined distance of the corresponding source pixel.

  • Patent number: 11730561
    Abstract: Apparatus and methods for providing three-dimensional printed oral stents are provided for head and neck radiotherapy. Movement of the jaw of the patient is simulated via a computer processor. Simulating movement of the jaw of the patient comprises rotating and translating a mandible of the jaw. A digital negative impression is transformed into a digital oral stent by adding support structures to the digital negative impression. The support structures facilitate three-dimensional (3D) printing of the patient-specific oral stent.

  • Publication number: 20230196795
    Abstract: A method for detecting an object having a known pattern with a boundary of a shadow overlying the known pattern includes: capturing, by a camera, a source image of the object; detecting a plurality of transitions between dark and bright regions of the source image and corresponding to the known pattern; determining an expected transition within the source image based on the known pattern and the detected transitions; determining an absence of the expected transition due to the boundary of the shadow overlying the known pattern; and determining a location in the source image corresponding to the expected transition based on a rate of change of brightness in the source image. A system including a camera and a controller configured to detect an object having a known pattern with a boundary of a shadow overlying the known pattern is also provided.

  • Publication number: 20230196794
    Abstract: A system and method for detecting seatbelt positioning includes capturing, by a camera, a near infrared source image of an occupant in a vehicle, determining a position of a head of the occupant in the source image, determining a region of interest for a seatbelt based on the position of the head; determining an oversaturation condition in the region of interest for the seatbelt, adjusting the source image to form an adjusted image compensating the oversaturation condition in the region of interest for the seatbelt, converting the adjusted image to a black-and-white image, and detecting the seatbelt within the black-and-white image. Adjusting the source image to compensate the oversaturation condition may include adjusting an exposure level of the source image based on a contrast ratio in the region of interest and/or based on detecting a predetermined pattern of the seatbelt within the region of interest for the seatbelt.
