Claim One:
1. A data acquisition and measuring device for acquisition and measurement of geometric data for at least one form motif associated with a glass for a spectacle frame, for the manufacture of ophthalmic lenses, similar or complementary to the glass, the device comprising: a support capable of holding the glass; an illuminator for illuminating the 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 receiving as an input each image captured by the video imaging system, the analyzer and processor being 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, wherein a first of said images is the projection of the form contour of the glass along a first direction of projection, on a first plane of projection, a second of said images is the projection of the form contour of the glass, along a second direction of projection, on a second plane of projection, and the first and second directions of projection form a non-zero angle therebetween.
