There are different techniques, that can be used for monitoring building
deformations, each is designed for a certain purpose and also depending on
many parameters, such as the shape of the construction, the quantity of the
deformation , the needed time to collect the necessary measurement and the
required accuracy .These techniques can be generally classified into
surveying and non surveying techniques .The surveying techniques include
conventional geodetic techniques and close range photogrammetry. This
paper proposes and discuses a more simple alternative approach for the
problem ofthe space intersection in close range photogrammetly, as applied
to structure deformation measuring.
In this research, a test field was used, for experimental determination of
the accuracy of the results obtained from the proposed approach, and of the
conventional techniques frequently used in close range photogrammetry
The accuracy obtained in this study, was determined by comparing the
coordinates in each technique with the original check points coordinate of
