This work describes the use of genetic algorithms in the design of photogrammetric networks. A system made for this purpose EPOCA (Evolving POsitions of CAmeras) is presented. With the system, a photogrammetric network can be designed using three-dimensional CAD-models of the object. The system provides the attitude of each camera in the network, taking into account the imaging geometry of the ...

Recent developments of digital cameras in terms of size of Charged Coupled Device (CCD) arrays and reduced costs are leading to their applications to traditional as well as new photogrammetric, surveying, and mapping functions. Digital cameras, intended to replace the conventional film based mapping cameras, are becoming available along with many smaller format digital cameras capable of precis...

In this paper we demonstrate the workflow of 3D modelling and photorealistic texture mapping based on close range imagery acquired with a mini-UAV (Unmanned Aerial Vehicle) and in terrestrial mode. For generation of a highly accurate 3D model, a combined photogrammetric processing of these images was required. The conducted workflow consists of the following steps: project planning, flight plan...

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...

In architectural surveying aimed to restoration and to conservation, close to the traditional two-dimensional vectorial representation in orthogonal projection, raster representation has gained considerable importance. Among all raster representations, the most widely-used is the digital orthophoto. The application of laser scanners as a new instrument for terrestrial survey together with firml...

During the last years commercial hyperspectral imaging sensors have been miniaturized and their performance has been demonstrated on Unmanned Aerial Vehicles (UAV). However currently the commercial hyperspectral systems still require minimum payload capacity of approximately 3 kg, forcing usage of rather large UAVs. In this article we present a lightweight hyperspectral mapping system (HYMSY) f...
