APPLICATION OF CLOSE RANGE PHOTOGRAMMETRY IN ARCHITECTURAL DOCUMENTATION

Abstract

Photogrammetry is the science in which the geometrical properties of an object are analysed in quantitative terms from their images recor-ded on photographs. Though the application fields of Close Range Photo-grammetry are numerous and quite diversified. The work in this disserta-tion is confined to photogrammetric applications in architectural docu-mentation The purpose is to acquaint the Architects and Archaeologists of the photogrammetric techniques and infuse in them interest for adopting these in their own interest and in national interest. The Architect has to design and foresee the construction of objects and spaces. He is also required to maintain a record of the architectural excellence of the past. There are multiplicity of agencies locking after the monuments of national heritage and architectural excellence in India. The various methods used by these agencies does not cope with the magnitude of the documentation requirements in the country. The CRP technique recording is fast, accurate, condensed. The problems occuring due to inaccessibility of the objects can be easily over come by this technique. The various steps in the photogrammetric recording of these monuments has been taken up in detail. The methodology derived was carried out on experimental basis, on the St. John's Church, University of Roorkee Campus, itself. The results obtained are quite remarkable. They can be furtrher refined by the introduction of suitable, sophisticated instrumentation It is also suggested that this technique should be utilised by various agencies responsible for preserving, maintaining and documenta-tion of the structures of national and architectural excellence on routine basis.
