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.

The present application is directed toward cargo scanning systems having scanners, each arranged to scan a respective object and generate a set of scan data, processors arranged to process each set of scan data to determine whether it meets a predetermined threat condition, workstations, and data management system arranged to direct data that meets the threat condition to one of the workstations for analysis.

An alignment device includes a holding device capable of holding the second workpiece, a moving device that moves the holding device toward the first workpiece, a mirror member capable of reflecting the second workpiece, the mirror member being arranged adjacent to the first workpiece, an image sensor arranged to be able to simultaneously and continuously capture the first workpiece and a mirror image of the second workpiece reflected on the mirror member, and a control device that performs feedback control of the moving device based on the calculated position of the second workpiece with respect to the first workpiece based on the first workpiece and the mirror image of the second workpiece, which are captured by the image sensor, to align the second workpiece with the first workpiece.
