Use camera positions embedded in the image information
« on: January 07, 2019, 03:21:24 PM »
I am fairly new to PhotoScan and I am running in to some undesired behavior.

Background:
We use PhotoScan to generate Orthomosaics of images taken of the seabed underwater with autonomous underwater vehicles. For each image the position and altitude is embedded and the navigation accuracy of our vehicle is extremely accurate, so the task should be as simple as "overlaying" the images. I have more than 90% overlap in each image and good detailed conditions.

Current situation:
When I try to align a set of images it first of all takes almost an hour for less than 300 images. Next up the alignment process completely skews the image positions, puts them at different altitudes, rotations and positions. I do not understand why this is even possible when all needed information regarding positions of the images is already embedded in the images.
See the two included images for reference.

I hope someone has the expertise to help me with this.

Hello Jesper,

If you are still observing alignment issues, please share the sample image set with support@agisoft.com, so that we could reproduce the problem and check how it could be resolved.
