In the framework of the Joint Archaeological Mission of the Universities of Bologna and Lecce at the ancient town of Soknopaiou Nesos (Fayyum, Egypt) a wide-range of geomatic methodologies were experimented (GPS, total station surveys, low-height aerial and close-range photogrammetry, Visual Reality, high resolution satellite imagery, etc.). The surveys were conducted with the aim of recording ...

Digital sensors, providing excellent quality with respect to geometry and radiometry, are more and more replacing traditional analogue photogrammetric data acquisition. Allowing for a completely digital data flow, particularly line scanners based on the three-line principle offer new opportunities for higher productivity and for cost reduction, since automated processing of orthoimages and DEM ...

Photogrammetric manipulation of imagery has been, for the major part, a point-based operation. The utilization of points remains to be convenient since few manually digitized points can be accurately obtained to carry out various photogrammetric orientation procedures (e.g., relative and absolute orientation as well as photogrammetric triangulation). On the other hand, the constant evolution of...

In the future field calibration and testing will be fundamental parts of photogrammetric production lines. The complete field calibration/testing concerns geometric, spatial, radiometric and spectral properties of the systems, and it is a crucial supplement to the laboratory calibration. In this article a method for complete calibration/testing of digital photogrammetric sensors, based on the S...

Photogrammetric mapping has moved from its classical objective, which is the process of reconstructing objects from analog frame cameras to more contemporary objectives such as automatic generation of spatial and descriptive information from digital imagery. The advent of Very High Resolution (VHR) imaging satellites opens new challenges and potentialities to geo-spatial mapping community, espe...

Point cloud registration is of great significance to the reconstruction high-precision 3D city models. There are some challenges when aligning aerial and close-range photogrammetric point clouds, such as huge view differences caused by different sights sensors, massive noisy points due error in dense matching, scale uncertainty since there no control for absolute orientation. To achieve complem...

Feature-based matching is commonly employed for object surface reconstruction in topographic and stereo close-range photogrammetry, but rarely in conjunction with convergent photogrammetric networks. This paper describes a new feature-based matching approach to automated 3D object reconstruction from highly convergent, multi-image networks. Geometric diversity and redundancy in the network desi...

Due to the recent improvements of automatic measurement procedures in photogrammetry, multi-view 3D reconstruction technologies are becoming a favourite survey tool. Rapidly widening structure-from-motion (SfM) software packages offer significantly easier image processing workflows than traditional photogrammetry packages. However, while most orientation and surface reconstruction strategies wi...
