In the last few years, digital photogrammetry became a major tool in archaeology. Specialists in this area recognize the advantage of fast and accurate mapping. Moreover they use photogrammetric techniques in order to record and document the findings of an archaeological site or the whole excavation. Mainly in prehistoric sites, there are several different(More)
This paper presents a modular software and hardware independent system for the 3D reconstruction in the area of culture heritage. This system can be used for the digitalization of 3D cultural objects, monuments and sites. The clouds of 2D or 3D scanned points (matrix oriented or scattered) even the 3D wireframe model are acquired by photogrammetric(More)
Deformation monitoring of slope instability and its surroundings supplies important information on the behavior of the slope in that it evaluates whether potential collapse may occur. Monitoring results may also be used in verifying design geotechnical parameters of slopes such as in mines and aid in the calculation of soil mass volume. The development of(More)
Close-range objects (industrial, architectural etc) are highly characterized by abrupt changes of their surface continuity. Thus no DEM (and thus orthoimage) of high quality can be generated unless these discon-tinuities are taken into account. Fortunately, these breaklines are mostly straight lines, and thus their automatic detection is not very difficult.(More)
Scoliosis is a 3D deformity of the human spinal column that is caused from the bending of the latter, causing pain, aesthetic and respiratory problems. This internal deformation is reflected in the outer shape of the human back. The golden standard for diagnosis and monitoring of scoliosis is the Cobb angle, which refers to the internal curvature of the(More)
The purpose of the paper is to investigate the Volunteered Geographic Information (VGI), which is still at a very early stage, to identify its use worldwide including characteristic examples and research its potential applications in Cultural Heritage andArchaeology as a new field for study. In the first part of the paper a brief review of the field is(More)
