Orthorectification is main and specific photogrammetric task. Digital technologies allow generation of precise orthoimages, whic h are obtaining the pixel accuracy. The realization of this process requires usage of precise and adequate object model that is generated by usage of different data sources. They include irregular set of points created by survey measurements, digitized cartographic data, raster DEM obtained from stereo pairs, or from points’ cloud gathered by laser scanning. The main steps of orthorect...

The filtering of binary images containing graphic and text information possesses typical peculiarities and uses heuristic processing procedures. At the same time the application of grey level methods for processing of digital images gives a lot of advantages. It is introduced an approach for the processing of binary images that is based on the adaptation of algorithms for grey level images like boundary detection, contour tracing, and line tinning. It is made the comparison of methods for binary filtering and corr...

The main principles and methods of interactive education are discussed. The requirements to this approach of educational process are formulated. The differences between practical training and learning process are discussed. Based on these principles there are shown the examples for deductive education on processing stages in digital image processing and digital photogrammetry. Main attention is pointed to the initial data collection for purposes of inner orientation, image calibration and relative orientation of s...
