Recognition of Short-Range Photogrammetry and Its Applications for Recording and Maintaining Cultural and Natural Heritage

Documenting, recording and maintaining information related to valuable monuments and cultural heritage is one of the steps in recognising and protecting historical works and buildings. Archaeologists and the experts of historical works by threedimensional modelling of real texture can work on virtual images of the desired building all over the world without the need of spending time and cost to travel to that place and perform any historical, materialogical and technological study. This research by investigating and introducing the application of new methods in cultural heritage registration seeks to investigate the application of photogrammetric science in the preservation and restoration of historical works and buildings. In short-range photogrammetry, using a series of images of an object, a precise model of its geometry can be achieved. This technique is typically used for documentations with complex geometric properties or a large number of architectural spaces and components such as mogharnas in mosques and other complex decorations. In short-range photogrammetric method, the coordinates of the boundary points of the parts are deduced and by comparing the geometrical parameters of the boundaries and finding similarities between the boundaries, the similar parts are graphically connected to each other to form an initial three-dimensional model for reconstructing the discovered objects.
