Échec de la reconstruction de la surface et de la production d'un True Ortho

Question

J'ai survolé une zone avec un DJI Matrice 4e, et j'essaie d'utiliser Drone2Map pour créer un True Ortho de la zone. Mon projet contient 2528 photos que j'essaie d'assembler. Le processus s'exécute et indique qu'il est terminé à 100 %, mais ne crée jamais le true ortho. En regardant le journal, je vois certaines erreurs indiquant des échecs, mais je ne sais pas comment les corriger.<\/P> J'ai déjà réussi à exécuter un projet avec environ 1900 photos sur ma machine, et je respecte les spécifications recommandées pour la machine. J'ai essayé plusieurs réglages et supprimé toutes les images non calibrées.<\/P> Toute aide serait appréciée !<\/P> J'ai joint le journal<\/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
