FIELD: photogrammetry. SUBSTANCE: proper points in left and right photographs are measured. Then relative orientation of photographs is carried out by which elements of similar projective conversion of coordinates of points from system of right photograph to system of coordinates of left photograph are determined by corresponding formulas. Coordinates of corresponding points of pair of photographs are transformed and corrections for relief are entered into coordinates of points of left and right photographs. Later exterior orientation of photographs is conducted. EFFECT: capability to process photographs generated by cameras with unknown or variable elements of interior orientation. 1 tbl
