FIELD: measurement.
SUBSTANCE: proposed group of inventions refers to measuring techniques and methods for measuring shape, dimensions and elastic properties, as well as constructing three-dimensional model of inner surface of hollow objects, in particular footwear. These methods imply movement of device inside measured object by indicators located on probes, creating uniform stress state on measured surface, obtaining relatively flat marking strip spatial data, with the help of which, three-dimensional model of oblect internal space is constructed, dimensions of which are obtained as result of measuring restored three-dimensional model. In this case, elastic properties are obtained as a result of scanning the same object with different force and measuring modulus of difference between finite and original dimensions of deformed body. Device for measuring shape, dimensions and elastic properties of inner surface of hollow objects, as well as construction of three-dimensional model of inner surface of hollow objects consists of housing, camera installed in it, two or more probes with indicators, and flat marking strip.
EFFECT: technical result, obtained from use of methods and devices, is to increase accuracy, reduce labor and time of measurement.
