Nepodařilo se rekonstruovat povrch a vytvořit True Ortho

Question

Létal jsem nad oblastí s DJI Matrice 4e a snažím se použít Drone2Map k vytvoření True Ortho této oblasti. Můj projekt obsahuje 2528 fotografií, které se snažím spojit dohromady. Proces proběhne a hlásí 100% dokončení, ale nikdy nevytvoří true ortho. Když se dívám do logu, vidím některé chyby, ale nejsem si jistý, jak je opravit.<\/P> Úspěšně jsem na svém počítači spustil projekt s přibližně 1900 fotografiemi a splňuji doporučené specifikace pro stroj. Zkoušel jsem různé nastavení a odstranil všechny nekalibrované snímky.<\/P> Jakákoli pomoc by byla skvělá!<\/P> Přiložil jsem log.<\/P> <\/P>

Hi @JuliaLenhardt , we did have a file path length issue that could occur during surface reconstruction in 2025.2 that should have been resolved with 2026.1. Have you had a chance to test the latest release to see if the problem is reproducible?

Regards,

Mark

Hi @MarkBarker1! I'm having the same issue as listed here, but digging into the ProjectLog I see it fails when attempting to write to the project folder, which of course doesn't make sense since the folder is editable. Could it be an issue with the number of characters in the path? I made it as short as possible. See the attached ProjectLog and the error about writing to files in "C:\DroneProducts\Testflight2\Project\Process\SurfaceRecon\Images	mp_0"

Thanks!

Hi @MarkBarker1 ,

So I do get result folders but they are usually empty. One thing it does produce is a csv file with the image metadata. After looking at that it did appear that I had images with different focal lengths. I removed the images with different focal lengths and it is producing the true ortho.

So my best guess is that I bumped the zoom trigger and it changed a setting that caused it to fail. I will have to fun it on a smaller area and then stitch them together.

Thanks,

Jaron
