METHOD OF OBJECT COMPLEX DISPLACEMENTS COMPONENTS MEASURING Russian patent published in 2017 - IPC G01B11/00 

FIELD: measurement technology.

SUBSTANCE: method of object complex displacements components measuring consists in use of test object associated with controlled object, latter image formation in image receiver, where scale is created in form of virtual labels, fixed at initial measurement cycle on image receiver surface in test object image predetermined points, by image movements relative to which judging on controlled object movements. Used test object is three-dimensional test object in form of ball with known diameter D, which is combined with test object, made in form of straight line section, so, that section crosses ball center. Controlled object movements informative components are determined according to four distances from corresponding virtual marks to test object image selected points, which characterize its linear movements along OX and OZ axes and turn about OY axis.

EFFECT: increasing in information content and accuracy of measurement due to enabling of selectivity to displacement components, which characterize turn and oncoming-withdrawing of object relative to corresponding coordinate axes, expansion of functional capabilities.
