Abstract. In this article, a method for the extrinsic calibration of 2D laser range finder and camera is presented. This technique produces 3D point cloud from test field by connecting to servomotor. study, ping balls standard photogrammetric targets were employed as field. Ping pong are used because they can be easily recognized in data camera. To calculate parameters between finder, these con...
Digital Photogrammetry has caused a revolution in the cartographic world thanks to a simplification of the photogrammetric systems. This fact, along with the ever greater need for fast and precise cartography, has increased the number of potential digital photogrammetric users. Despite the simplification of these systems, it still important to take into account the high necessary investment of ...
We derive exact results for displacement fields that develop as a response to external pinning forces in two dimensional athermal networks. For triangular lattice arrangement of particles interacting through soft potentials, we Green's function formalism which use produced by localized forces. show the continuum limit decay $1/r$ at large distances $r$ away from force dipole. Finally, extend ou...
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...
Within the paper the results of several studies will be presented, which have been carried out at ifp in order to evaluate the performance of digital airborne pushbroom cameras for photogrammetric data acquisition. In close cooperation with the respective system developers the DPA (Digital Photogrammetric Assembly) of DASA, the HRSC (High Resolution Stereo Camera) and the WAAC (Wide Angle Aircr...
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...
We present a photogrammetric system for on-line pose measurement of a robot. The system is based on photogrammetric measurement techniques, namely resection. We describe the theoretical foundations of our approach as well as early details of our implementation and hardware set-up. The results achieved are compared to those of a commercial ball-bar system.
