METHOD OF CONTACT-FREE DETERMINATION OF SPATIAL COORDINATES OF POINTS OF OBJECT Russian patent published in 2001 - IPC

FIELD: photogrammetry, civil engineering, architecture, medicine and other applications. SUBSTANCE: method is related to determination of spatial coordinates of points of object, parameters of surface of object by photographs including those having no coordinate marks. Method includes photographing of object from several positions ( points of space ), identification of points of image of object on each photograph, measurement of distances between identified points on each photograph and computation of spatial coordinates of points of object - X, Y, Z proceeding from proposed mathematical formula. While computing spatial coordinates of points of object focal distance, linear and angular elements of external orientation of taken photographs are also computed. Object is directly photographed by camera having no coordinate marks. EFFECT: simplification of photogrammetric method of determination of coordinates of points of object and reduced cost of these operations. 3 cl, 1 dwg
