Automatic Photography Device FocusSphere for Micro Close Range Photogrammetry

The paper presents basic construction principles of a new, original device called FocusSphere. The device is used to acquire photographic data and their geometrical properties for the purpose of close range photogrammetry. First of all, the paper shows how micro close range photogrammetry is successfully used in many areas. Subsequently, the construction of the device is briefly presented. The most important features and their influence for obtained results are discussed. The paper portrays also the process of determining the orientation of images for any FocusSphere program. For this purpose total station and photogrammetric measurements are made. The results of the measurements are analysed due to determine movements characteristics of the machine. Finally, the paper depicts main similarities and differences between FocusSphere and existing, conterminous technologies. The advantages and disadvantages of each solution are discussed.
