COMPUTER-IMPLEMENTED METHOD FOR INDIVIDUALISING A SPECTACLE FRAME ELEMENT BY DETERMINING A PARAMETRIC SUBSTITUTION MODEL OF A SPECTACLE FRAME ELEMENT, AND DEVICE AND SYSTEMS USING SUCH A METHOD
A spectacle frame element is individualized by adapting a parametric model of the spectacle frame element to the head of a spectacles-wearer. A parametric substitution model, having at least one parameter, for the parametric model of the spectacle frame element is determined by specifying a plurality of instances of the parametric model in the form of realizations of the parametric model using concrete parameter values, at least one basic instance and at least one parametric deformation map for the at least one basic instance are determined from the predefined instances, the at least one parametric deformation map mapping the at least one basic instance to instances of the parametric model, and the parametric substitution model being determined at least from the at least one basic instance and the at least one parametric map.

A frame for a head mounted device including: a front part; a first temple configured to be electronically connected to the front part via a first connection and including a battery providing electrical power arranged in a cavity in the first temple and connected electrically to the first connection; a second temple configured to be electrically connected to the front part and having a cavity therein configured to receive therein at least one electronic module; and a second connection configured to connect electrically the battery of the first temple to the at least one electronic module of the second temple via the front part to receive power therefrom.
A METHOD AND SYSTEM FOR PREDICTING AN EYE GAZING PARAMETER AND AN ASSOCIATED METHOD FOR RECOMMENDING VISUAL EQUIPMENT
This method for predicting at least one eye gazing parameter of a person wearing visual equipment includes steps of: measuring data of at least two individuals wearing visual equipment, such data including at least head motion parameters and eye gazing parameters of the individuals; measuring head motion parameters of the person in real-life conditions; comparing the head motion parameters of the person with the head motion parameters of the at least two individuals; and predicting the at least one eye gazing parameter of the person at least on the basis of the results of the comparing step and of the eye gazing parameters of the at least two individuals.
METHOD FOR OBTAINING DATA REPRESENTATIVE OF THE OUTLINE OF A SHOULDER DELIMITING A STEP-BACK PORTION IN AN EYEGLASS
The method includes the steps of: providing spectacles including a template eyeglass having a mounting portion inserted in a groove of an arc and being to be replaced by a prescription eyeglass having a step-back portion with the same conformation as the mounting portion; providing a set of visible marks on the template eyeglass independently of the arc; having an outline editor providing a visualization of the template eyeglass provided with the visible marks; determining through observation of the spectacles the location—with respect to the visible marks—of points of the arc from which the template eyeglass projects; entering on the provided visualization the so determined locations of the points of the arc; and outputting from the editor the data representative of an edited outline based on the point locations so entered on the provided visualization, whereby the edited outline is the outline of the shoulder.
Method and assembly for verifying the mounting of an ophthalmic lens in a frame
Disclosed is a method for verifying the mounting of at least one ophthalmic lens in a frame of a pair of spectacles designed to be worn by a subject, the method including the steps of: obtaining a test image of the frame in which the at least one ophthalmic lens is mounted, the at least one ophthalmic lens including at least one marking visible in the test image; comparing the test image of the frame with a reference image of the frame worn by the subject without the at least one ophthalmic lens; and verifying the mounting of the at least one ophthalmic lens in the frame based on the previous comparison.

A system and method for customization of an eyewear is disclosed. The system includes a face scanning subsystem configured to scan a face of a user to capture one or more predefined details, an eyewear display subsystem configured to display one or more collections of the one or more components, an eyewear customization subsystem configured to receive a selection input representative of one or more components selected from the one or more collections, a first level eyewear customization subsystem configured to receive one or more customization input representative of one or more customization parameters, an eyewear assembling subsystem configured to assemble the eyewear associated with the user, a testing subsystem configured to test in real time, one or more customized eyewear, a second level eyewear frame eyewear customization subsystem configured to customize the one or more customization parameters in real time.
METHOD FOR DETERMINING THE OPTICAL CENTER POINT OF THE LENSES OF SPECTACLES TO BE MANUFACTURED FOR A SPECTACLE WEARER
A method and a device are described for determining the optical center point of the lenses of spectacles to be manufactured for a spectacle wearer, whose head is imaged from the front using a digital camera (10), wherein the location of the pupils (16) and the interpupillary distance (20, 21) are determined with the aid of an image evaluation program to define the optical center point of the lenses. To provide advantageous conditions, it is proposed that the face of the spectacle wearer is imaged having a measurement frame (1) held on the head via a nose rest (4) and earpieces (3) and having a view oriented on a fixation point (13) fixedly associated with the camera (10), a front region of the measurement frame (1) has two lateral marking points (7) and a middle marking point (8) placed frontally in front of these lateral marking points (7), the angles of the viewing lines (15) in relation to the image plane are determined with the aid of the image evaluation program from the mutual distances and locations, which are measured in the facial image, of the pixels of the three marking points (7, 8) and the pupils (16), before the measurement points (19), which are corrected with respect to parallel viewing lines (17), are ascertained to determine the interpupillary distances (20, 21) in relation to the nose rest (4).
Methods and devices for determining the position and/or orientation of a spectacle lens on a mounting
A spectacle lens with has permanent markings is mounted on a mounting, in particular a suction mounting. The apparent location of the permanent markings is detected on the spectacle lens with a detection device. Additionally, the spectacle lens is illuminated eccentrically with respect to an optical axis of the detection device using eccentric light sources. Reflections from the lights sources on the spectacle lens are likewise detected. On the basis of the detected reflections and the apparent location of the permanent markings, the position and/or orientation of the mounted spectacle lens are determined.
METHOD AND APPARATUS FOR DETECTING OPTICAL DEVICE MIS-ADAPTATION
An apparatus for detecting mis-adaptation of an optical device to a wearer includes processing circuitry configured to receive and store over time head data relative to the head of the wearer when wearing and using the optical device, process the head data based on head data patterns associated with known mis-adaptation of an optical device to the wearer of said optical device, and detect mis-adaptation of the optical device to the wearer by matching the received and stored head data with head data patterns associated with mis-adaptation.
