Stitching long series of gopro images
« on: August 29, 2017, 09:08:56 PM »
Hi,

I'm trying to stitch together long bands of gopro images--maybe 100-300 images in the X direction, with at most 2 images  "side-by-side" in the Y direction at any given location. The images are maybe 2m above the ground, facing down. Each image is geotagged, although the GPS values may not be high quality.

We are using maximum image matching accuracy and dense cloud quality, and building the orthomosaic based on elevation data.

The resulting orthomosaic is warped and sometimes totally unusable.   You can visit https://www.dropbox.com/sh/dstvazzbn8ooacw/AAA_E-qqfGbmwE07-0z41E8Na?dl=0 and view gopro_*.pdf to see the orthomosaics in question (fonts are not working currently, but you can see the images).

When stitching manually, it's possible to re-align the frame of reference so that the orthomosaic is not warped. But we'd like our process to be totally automatic. Does anyone have any suggestions?
