Guk A.P., Beloshapkin M.A. Digital orthophoto generation in SDS technology

Workshop ISPRS. - Commission V. - Workshop 4. - Israel, Haifa. - 1997. - Presented Paper.Digital orthorectification software Ortho-Photo-SDS has been designed for desktop photogrammetric system SDS. Complete processing, including internal, relative and absolute orientation, DEM creation and orthorectification of color aerial images was implemented in 32-bit Windows-95 / Windows NT application. A noval semiautomatic technology for conjugate point extraction allows to save the operator from difficult work, reserving the creative part for him. The perceptual uniform processing of chromatic coordinates is implemented according to CIE recommendations. The fast orthorectification algorithm develops a speed 18 MBytes of digital orthoimage per minute working on Pentium-120.
