Abstract
In this thesis a study of the application of close range photogrammetry to the restoration of architectural features is reported.Ivestigations of both data acquisition and data reduvtion were carried out in order to establish the optimum accuracy for close range photogrammetric projects. An extensive study has been carried out on non-metric photography, as this was considered to be a main source of data acquisition.
A new mathematical formulae for estimating the accuracy of object point co-ordinates for any camera positions are developed.The optimum camera positions that maximize the accuracy of these object points are obtained.
A new technique of data reduction from non-metric photography in the restoration of partial damaged architectural features was developed.Different techniques including the new developed one were applied in order to reconstruct the dimensions of the roof of part of york minster which was damaged by fire in 1984.
The main conclusions and recommendations are presented in chapter 6.
