摘要： This method, which allows acquisition and computation of geometrical data of at least one pattern associated with an ophthalmic object (6) for manufacturing ophthalmic lenses similar to the object or complementary thereto, is of the type in which a device (12) for acquiring and computing geometrical data is used, which comprises: a transparent support (13) adapted for bearing an ophthalmic object; on one side of the support, means (17) for illuminating this support; on the other side of the support, a video camera (25) adapted for producing a video signal representative of at least one pattern associated with the ophthalmic object laid on the support; and signal processing and analysis means (27) receiving at the input the video signal produced by the camera, and adapted for computing and providing the geometrical data. The method is characterized in that: (a) a verification pattern independent of said geometrical data is traced on the ophthalmic object (6), this verification pattern being asymmetrical relatively to each of two axes perpendicular to each other; (b) the ophthalmic object is positioned on the transparent support (13) of the acquisition and display device (12); and (c) by means of said device (12), said verification pattern is optically captured and analyzed.

摘要： This data acquisition and measuring device for acquisition and measurement of geometric data for at least one motif associated with a glass for a spectacle frame, for the manufacture of ophthalmic lenses, similar or complementary to the glass, comprises a support capable of holding the glass, an illuminator for illuminating this support, a video imaging system for capturing images oriented towards the support and capable of capturing at least two images of the contour of the glass placed on the support, and a signal analyzer and processor that receive at the input each image captured by the video imaging system. The analyzer and processor is capable of measuring the distance from at least one point of the form contour of the glass to a reference plane based on said images.
