People’s Republic of China is one of the most rapidly developing countries in the world today. There is a great demand on highly actual and accurate spatial information of the whole country, especially of West China which becomes the focus of development of the Chinese government right now and in the next years, but where still not enough topographic maps are available. This raises great challe...
The modern World is constantly changing and education is one of the last things that do not get obsolete. However, its techniques must be adapted to newer resources and environments. Particularly, Photogrammetry is a science that has suffered from so many abrupt changes in the last fifteen years. We have passed from an enclosed and convergent dynamic characterized by Stereoscopic Aerial Photogr...
In this paper, the developments related to an autonomous airborne mobile mapping system for photogrammetric processing will be presented. During the last years the author has been involved in several projects related to mobile mapping using an autonomously flying model helicopter, a so-called mini UAV (Unmanned Aerial Vehicle). The overall motivation of using mini UAVs for mobile mapping, the d...
Historical photographs contain high density of information and are of great importance as sources in humanities research. In addition to the semantic indexing of historical images based on metadata, it is also possible to reconstruct geometric information about the depicted objects or the camera position at the time of the recording by employing photogrammetric methods. The approach presented h...
3D spatial data acquired from aerial and remote sensing images by photogrammetric techniques is one of the most accurate and economic data sources for GIS, map production, and spatial data updating. However, there are still many problems concerning storage, structuring and appropriate management of spatial data obtained using these techniques. According to the capabilities of spatial database m...
In this pilot study, the authors tested whether photogrammetry can replace or supplement physical measurements made during autopsies and, based on such measurements, whether virtual computer models may be applicable in forensic reconstructions. Photogrammetric and physical measurements of markers denoting wounds on five volunteers were compared. Virtual models of the volunteers were made, and t...
