An adjustment of photogrammetry combined with the observation equations obtained from the geodetic survey

Abstract

In the conventional phtogrammetry, the adjustment is carried out using geodetic observations. However there may include errors resulted from not only photogrammetic but also geodetic data. It is most reasonable to adjust those data simultaneously for errors of geodetic survey. The simultaneous adjustment of photographic and geodetic data such as distances, angles or heights has been developed by the authors. It was noted that the results show better than the ones by the conventional method.
This paper also discusses the method for the detection of gross error of control points. It is obvious that gross error over 10m can be detected by the developed simultaneous adjustment with orientation of a single photograph regardless of position, coordinates and direction of gross error.
Another noticeable result discussed in the presented paper formulates a method to estimate a gross errer, and it is demonstrated that this proposed method is able to estimate accurately and easily the position, coordinates and megnitude of gross error.
