摘要： A computer-implemented method for establishing the representation of the edge of a spectacle lens or of a left spectacle lens and a right spectacle lens for a spectacle wearer is disclosed. The method includes: providing image data relating to the spectacle wearer with a worn spectacle frame; calculating information data derived from the image data; calculating a deterministically optimizable cost function linking the information data with spectacle lens data, wherein the spectacle lens data describe the spatial extent of at least one spectacle lens held in the spectacle frame; and setting a curve of an edge of the spectacle lens or of the left spectacle lens and the right spectacle lens by optimizing the cost function.

摘要： Centration parameters for fitting spectacle lenses to a predetermined spectacle frame and to the head of a subject are determined with a computer-implemented method. At least two calibrated images, recorded from different recording directions, of the head of the subject wearing the spectacle frame are provided, wherein geometric parameters are established by geometric position determination. The geometric parameters describe the position of the eyes and the geometry of the spectacle frame, and the centration parameters are calculated from the geometric parameters. Further, a three-dimensional model for the spectacle lenses, which are to be received in the spectacle frame, is fitted to the geometry of the geometric parameters that describe the geometry of the spectacle frame.

摘要： A depth information detection device detects an item of depth information relating to a user's head, including a distance from the user's head to the device. On the basis of this depth information and, if applicable, additional information such as images, an evaluation device determines the desired parameters for fitting the spectacles, such as centering parameters.

摘要： A device for determining centering parameters for the adjustment of spectacles includes a camera support partially surrounding an inner area that is open at the top, bottom and to the rear; and at least three cameras arranged between two free ends of the camera support and pointing towards the inner area, the camera support having an illumination system in order to illuminate the inner area. The illumination system is designed to light the inner area such that the light intensity, at least at each point in a region extending over a height of 20 cm and a central angle of 180 degrees of an outer cylinder surface having a diameter of 20 cm and formed in the inner area, deviates by a maximum +50% and −30% from a predefined desired value.

摘要： A computer-implemented method detects the position of a corneal vertex of an eye from a frontal image of a head and a lateral image of the head. The front and lateral images are calibrated to one another, and the position of the corneal vertex in space is determined from the frontal image and the lateral image with a geometric position determination.

摘要： A computer-implemented method for determining a representation of a rim of a spectacles frame or a representation of the edges of the spectacle lenses is disclosed, wherein at least two calibrated images taken from different viewing angles of a head a subject wearing the spectacles frame or the spectacles are provided, and wherein data for at least portions of the rims of the spectacles frame or the edges of the lenses are detected in each image. Further, a three-dimensional model of the spectacles frame or the spectacles is provided, based on geometric parameters, and the geometric parameters are optimised to adapt the model to the detected edges.
