  • Shape measuring device, shape measuring method, and glass plate manufacturing method
    Patent number: 10059616
    Abstract: A shape measuring device includes: a predetermined pattern; an image pick-up section that captures reflected images of the predetermined pattern on the front face and back face of a transparent measurement object; a calculating section that calculates an inclination angle of at least the front face or the back face from the reflected images; and a determining section that determines a shape of at least the front face or the back face. The predetermined pattern includes a plurality of elements, and one end and the other end of each element of the plurality of elements, which are formed in a direction perpendicular to the extension direction, are deviated from each other in the extension direction.
