  • Curvature measurement apparatus
    Patent number: 10704886
    Abstract: An embodiment relates to a curvature measurement apparatus. The apparatus includes a first curvature measurement unit configured to, upon a curvature of an object to be measured being relatively greater than a first curvature, measure the curvature of the object to be measured; and a second curvature measurement unit configured to, upon the curvature of the object to be measured being relatively smaller than a second curvature, measure the curvature of the object to be measured, the second curvature being relatively greater than or equal to the first curvature. The curvature measurement apparatus can improve an accuracy of a curvature of an object to be measured.
