Determining the texture deformation of historical buildings with photogrammetric method

In this thesis study, photogrammetric documentation and deformation analysis of cultural and historical buildings with image segmentation and classification techniques caused by moisture and isolation problem is aimed with combine use of digital and thermal camera. To realize this aim, 3D test object was designed and manufactured to perform geometric calibration of digital and thermal cameras. The geometric calibration of Nikon D3X SLR (50 mm and 20 mm focal length) digital camera and Flir A320 thermal camera was performed. The Azapkapı Sokullu Mehmet Paşa Mosque was selected as test side and developed approach was tested. The exterior orientation parameter of the recorded image in two different side (study area 1 and study area 2) were determined with bundle block adjustment and rectified images were generated with using digital and thermal images. The multi resolution segmentation was utilized for digital and thermal images with determined scale, shape and compactness parameters using the rectified images. The classification was performed with fuzzy algorithm and generated classes were recorded as vector file. The deformation analyses caused by moisture and isolation problem were not possible using classification results from digital images in both study area (study area 1 and study area 2). The deformations, caused by moisture and isolation problem, have been analyzed easily from ground to different height level using the thermal classifications from thermal images and thesis study objectives accomplished successfully. In defiance of the analyses which caused by moisture and isolation problem with the digital camera images, this deformations have been analyzed easily from ground to different height level using the thermal classifications from thermal images and thesis study objectives accomplished successfully.
