Small number of photos, orthophoto coordinate accuracy problem

Hello, I use a small number of photos, such as 20 photos, and the orthophoto have a large offset on the map. How do I optimize it? Thanks everyone for any help!

Ground Control Points might be your best bet.

What hardware did you take the images with?

thanks a lot, so when I use --Split 50, submodels cannot be aligned,the final merged orthophoto did not achieve the best results.

Try not using the split command.

Thank you!
