Simple Methods for Close Range Photogrammetry Surveying of Rural Industrial Constructions

Classical methodologies used in data collection for architectural documentation are studied (surveying topographic, photogrammetry, manual methods, etc). Different aspects are analysed in order to select the most suitable approach, always taking into account the specific determining factors. The suggested technique is in line with the so-called close range photogrammetry by simple methods. Its utilization as an easy application, low-cost method is analysed so that it can be used without need of specialized training, thus facilitating its universalization by means of an increase in the number of users and, consequently, a rise in the number of records. The suggested method is based on the use of low-cost conventional digital cameras, plumb lines and monoscopic digital photogrammetric stations, complying with the directives of the International Committee for Architectural Photogrammetry (CIPA). The studies is presented with the obtained numerical results and the graphical results in plan form, as well as three-dimensional models of the structures, rendered with their original textures, as a proposal for their documentation and conservation. Once digital data is archived, everyone can access the full document through internet in order to obtain metric information of the constructions, to make 3D models or to develop photo-models using realistic textures.
