1. Introduction 
The photogrammetry, using metric cameras, is based on the mathematical model 
of a central perspective. But the geometry of the photos is a little differ- 
| ent from this model. The systematic differences are usually named as syste- 
1! matic image errors although they are errors of the mathematical model. 
Hn In the bundle block adjustment the main systematic image errors can be 
determined by self calibration, using additional parameters. The additional 
Ü parameters can fit only the main systematics and they are not able to fit 
i systematic errors with slight changes from photo to photo. 
P The remaining systematic image errors after precise bundle block adjust- 
ment with additional parameters are analysed. 
2. Investigated Material 
  
| The following bundle blocks are analysed for remaining systematic image 
T errors. The photos are measured with precise.comparators or analytical 
("a plotters. The object points are signalised.
