Abstract / Hauptanspruch
A measurement device (1) for a threaded object (3) defining a spatial reference system (X, Y, Z) and has two optical sensors (5', 5") fixed on a yoke (40), movable in a spatial reference system (X', Y', Z') to make measurements on external threadings. A variant of the device (1) encloses also a third optical sensor (16) for making measurements on female threadings. A computer assembles a first matrix that describes the quadratic form representing the threaded object in the spatial reference system (X, Y, Z), thus providing the relationship between the two spatial reference systems.
