METHOD FOR DETERMINING RELIEF AREA Russian patent published in 2005 - IPC

FIELD: geodesy.

SUBSTANCE: method includes filming planned areas from board of spacecraft, on which optical stereo-filming system is mounted. Array of digital models of area is received using aero-space means with high resolution. Digital area models matrix of area portion is separated on fragments. Two-dimensional space spectrum is calculated and autocorrelation function for fragment signal is calculated for signals b(x), b(y). relief area is determined by numeric integration using specialized PC software for surface integral S=S[b(x), b(y)], dependently on calculated values b(x), b(y).

EFFECT: higher precision, higher reliability, higher trustworthiness.
