Got it!!! Thanks!!! I thought in the simple interface, hugin was going to crop them for me, guess i was wrong. Thanks again! On Thursday, September 6, 2018 at 5:46:28 PM UTC-5, panostar wrote: > > > > On Thursday, September 6, 2018 at 10:32:21 PM UTC+1, jiang...@gmail.com > wrote: >> >> Hello

It is just a 2D Object. Stitching works very well if i only optimze TRx and TRy. But i try to understand in which dimension these Parameters. On a camera movement of round about 30cm i get a TRx of 0.521 . I try to understand this number. -- A list of frequently asked questions is available

Kai, is this a 3D object? I believe Mosaic Mode is meant for 2D images like a picture or mural. A 3D object will introduce parallax errors that will make it hard to stitch unless you are really careful in placing control points and then masking out any overlaps. Kind regards from Canada. Don

Just a follow up on the previous discussion. I have tried 3 different methods this morning. 1. crop without masks (exactly the same as original post), quality is still bad as expected. 2. crop with masks, the output is bad as well. 3. masks without crop (from Greg's pto file), the

Yes, the XYZ mosaic optimisation will resolve quite extreme parallax errors, but only for features on a single flat plane in the scene. In this case your ground is close enough to being planar, so Hugin can fix parallax for all photos, not just the nadir. By default this plane needs to be

You would do better to set the zoom to 12mm. At 8mm, you waste half of the available pixels on black space surrounding the image circle. At 12mm, you still get full 180 degree coverage vertically and perfectly adequate overlap horizontally. Furthermore, you then don't include the black bit of
