Title: Modern Methodologies for Photogrammetric Point Determination
Abstract: Three kinds of operational methodologies and their mathematic models of modern aerial photogrammetric point determination are described.A combined bundle block adjustment system WuCAPS,which can make conventional bundle block adjustment,GPS-supported bundle block adjustment and POS-supported bundle block adjustment,is developed based on the basic mathematic models mentioned above.Real aerial photographs,at image scales from 1∶2 500 to 1∶60 000,with POS data taken over various topographies in China were processed by WuCAPS.The accuracies of photogrammetric point determination from three methodologies are compared and analyzed.The empirical results have verified that the coordinate accuracies of the photogrammetric points can meet the requirements of the specifications of topographic mapping.However,it is necessary for topographic mapping to adopt the most economical and the most operational methodology.
