Abstract
The automatic measurement of targets is demonstrated by means of a theoretical example and by an interactive measuring program for real imagery from a réseau camera. The used strategy is a combination of two methods: the maximum correlation coefficient and the correlation in the subpixel range. Furthermore, a variable template is interactively derived at the beginning in order to eliminate some unknowns which ensures a more stable solution. Various possibilities are outlined how blunders can be detected and how the results concerning accuracy and speed can be further improved. The produced interactive software is also part of a computer-assisted learning program on digital photogrammetry.
