The paper presents the concept of an information system dedicated to storing, presenting and publishing via the Internet numerical and digital results of photogrammetrical measurements from various close range applications. The presented information system is not an on-line application for real-time Internet measurements. In the system a standard client-server model was applied. Three levels of...

This work describes the use of genetic algorithms for automating the photogrammetric network design process. When planning a photogrammetric network, the cameras should be placed in order to satisfjr a set of interrelated and competing constraints. Furthermore, when the object is threedimensional, a combinatorial problem occurs. Genetic algorithms are stochastic optimization techniques, which h...

an important issue in implementation of a gis system is preparation of data to be entered in gis. to produce spatial data for gis using photogrammetric techniques, conventional method is to apply photogrammetric and gis systems individually (off-line procedure). this approach is costly, time consuming and somehow unreliable due to the fact that 3d photogrammetric model is not available at the t...

A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...

Laser scanning (LIDAR) is a recent technology that is receiving an increasing interest from professionals dealing with mapping applications. The interest in LIDAR is attributed to the rich geometric surface information provided by the data in the form of dense non-selective points. On the other hand, photogrammetric processing of stereo-images provides an accurate surface model represented by f...

Close-range photogrammetry has been used in many applications in recent decades in various fields such as industry, cultural heritage, medicine and civil engineering. As an important tool for displacement measurement and deformation monitoring, close-range photogrammetry has generally been employed in industrial plants, quality control and accidents. Although close-range photogrammetric applica...
