Falha ao reconstruir a superfície e produzir True Ortho

Question

Eu voei em uma área com um DJI Matrice 4e, e estou tentando usar o Drone2Map para criar um True Ortho da área. Meu projeto tem 2528 fotos que estou tentando unir. O processo é executado e diz que está 100% concluído, mas nunca cria o true ortho. Quando olho o log, vejo algumas coisas que dizem que falharam, mas não tenho certeza de como corrigi-las.<\/P> Eu já executei com sucesso um projeto com cerca de 1900 fotos na minha máquina antes, e atendo às especificações recomendadas para a máquina. Tentei várias configurações e removi quaisquer imagens não calibradas.<\/P> Qualquer ajuda seria ótima!<\/P> Anexei o 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
