Comparison of photogrammetric data production with oblique photogrammetric method and classical photogrammetric method

The purpose of this research thesis is to examine the multi-camera systems that are becoming widespread with the developing technology and to compare the oblique photogrammetric productions with the classical method. In this context, the types and classifications of the oblique cameras used widely has been examined. The work flow charts regards to classical and oblique photogrammetric method are developed and the detailed information are given in this scope. In this thesis study, the area within approximately 69 hectares is determined and the data set is produced by classical method and by oblique photogrammetric method using multi-camera systems for this determined area. The produced data sets were compared with each other. The data sets produced by these two methods are listed below; •Point cloud •Digital surface model (DSM) •Digital terrain model (DTM) •Mesh model Thus, it is aimed to compare these two methods with each other and to reveal the advantages of the data sets produced by the oblique photogrammetric method over the classical method.
