Problems aligning big Dataset in one aligment
« on: August 03, 2022, 11:16:29 PM »
Hello everyone,

i have a dataset of ~2400 images capturing a schoolbuilding.

When trying to align these images, only 1750 got aligned in one attempt. I aligned the others in 2 seperate chunks, which worked fine.
I planned to try to align the chunks together using Align Chunks point based, but it also did not seem to work.

I have 2 chunks containing images capturing the buildings facades at low distances at mostly 0°, and one chunk capturing the building from above at -90° to roughly -50°.
In my experience, the overlapping areas should be more than enough to get the images to align in one go, but i cannot seem to get it working.
Any ideas what i could do differently to get these images to align in one go?
I attached images of the chunks where i marked the same facade in each for better orientantion.

You can try to place markers and align your chunks with those. Or to register your clouds with the ICP tool implanted on CloudCompare.
Best regards

What parameters did you use for alignment in one processing? (you can just click on Tie Points of that attempt and make a screenshot - parameters of alignment will be shown in bottom left corner)
