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.

A curvature measurement apparatus, comprising:
- 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, wherein the second curvature is relatively greater than or equal to the first curvature, wherein the object to be measured is a finger of a person, and the apparatus further includes:
- a sheath body, configured to be worn on the finger, wherein the first curvature measurement unit and the second curvature measurement unit are disposed in the sheath body.
A curvature measurement method, comprising:
- comparing a curvature of an object to be measured to a first curvature;
- measuring the curvature of the object upon the curvature of the object being relatively greater than the first curvature;
- comparing the curvature of the object to be measured to a second curvature, the second curvature being relatively greater than or equal to the first curvature;
- and
- measuring the curvature of the object upon the curvature of the object being relatively smaller than the second curvature.
