The solution to the problem of constructing the system capable to recognize objects and to determine their coordinates via images is presented. The theoretical approach based on a set of features invariant to such affine plane transforms as the scale changes and rotations is developed. The algorithm for computation of the invariant features of the objects and the optimization procedure for determining its coordinates are suggested. The algorithm involves the Hough-transforms (HT), threshold processing in the HP parameter plane, logarithmic transform of the coordinates, and direct calculation of the invariants with respect to the above groups of the affine transforms. The block-diagram of the iconic system is presented. The algorithm application to aircraft images processing is provided.
