Hugin

'Optimise now!' generates new parameters on each click

Asked by Markus Overesch

Hi,
we have setup a Hugin project to stitch some aerial images.
In the tab 'Optimiser' we activated the optimisation for yaw, pitch, roll, X, Y, Z and objective a, b, c. The first image is our anchor.
The are multiple control points between our images.
Using the 'Optimise now!' button calculates new parameter values each time we click on it. Some of our angles jump from 6 -> 17 -> -27 -> 36 degree.
Is this an expected behaviour?
How can we get a non changing result for the parameters from the optimisation?

Thank you
Markus

If the result is not stable it indicates that there are too little constraints.
Either add some line control points or reduce the number of optimized parameters.
E.g. without line control points you should not optimize yaw/pitch/roll of the anchor. Also you should not optimize z for all images.

Can you help with this problem?
