Modelling and Visualization of Three Dimensional Objects Using Close Range Imagery

Databases created for various user applications require different types of geometrical and thematic data. The physical shape, volume, and texture of spatial objects are usually requested for objects concerned with such areas as, architecture, archaeology, medicine, or industry. For many years, wide range of close range systems have been used for acqisition of the source data. In the last decade, the laser technology, non matric digital imagery or automatic systems based on moire projection have become popular for close range data collection. In this paper, results of some pilot projects carried out in the Institute of Photogrammetry and Cartography at Warsaw University of Technology, will be presented. The shape and digital surface models of three various types of 3D objects of different size, shape and texture, concerned with architecture, archaeology and medecine applications, were determined. The popular amatour digital cameras and moire projection automated system were used for data acqusition. The main principles of data acqisition and processing, as well as the results and accuracy of 3D modelling of the selected objects, will be discussed in this paper.
