20100260380 | DEVICE FOR OPTICALLY MEASURING AND/OR TESTING OBLONG PRODUCTS - A device for optically measuring and/or testing oblong products moving in a longitudinal direction. The device includes a plurality of cameras arranged in a plane perpendicular to the longitudinal direction, and distributed around the longitudinal direction. Each of the cameras has a fixed focus. The device further includes a displacing device adapted to displace each of the cameras simultaneously and jointly over the same distance toward the surface of the oblong product to focus on the oblong product, wherein the device defines a center that is located in the plane. | 10-14-2010 |
20100245843 | METHOD FOR MEASURING THE ROUNDNESS OF ROUND PROFILES - A method for measuring the roundness profiles moved forward in longitudinal direction inside a rolling mill, using two laser scanners, respectively provided with a light-sensitive sensor and a laser. At least three shadow edges that fit against the round profile to be measured and enclose the round profile to form a polygon are generated and measured and the corresponding tangents are computed. The method includes: a) determining a center (Z | 09-30-2010 |
