  • Computer-implemented method for determining a position of a center of rotation of an eye using a mobile device, mobile device and computer program
    Patent number: 11849999
    Abstract: Computer implemented methods for mobile device, mobile devices and computer programs are utilized for determining the center of rotation of the eye. An image of an eye of a person is captured in at least two positions of the mobile device, and the position of the center of rotation is determined based on the images and the position. In a similar manner, optionally a pupil position may be determined.
    Type: Grant

  • Method for calibrating objects in a reference coordinate system and method for tracking objects
    Patent number: 10846883
    Abstract: A method for calibrating an object includes determining a position and an alignment of the object in a reference coordinate system, determining the position of at least three measurement spots by at least one capture apparatus, determining a target spot having a fixed spatial relationship with the measurement spots, determining a spatial relationship between the target spot and a tracking spot located on the object by virtue of the tracking spot being positioned at a calibration spot, and determining the spatial location of the calibration spot by a sensor.
