Échec de la génération du maillage 3D

Question

Depuis le passage à Drone2Map 2024.1 et 2024.1.1, je n'ai pas pu créer un maillage 3D. Tous les autres produits, y compris le nuage de points, se traitent correctement. <\/P> J'ai utilisé des données provenant de plusieurs drones et sur plusieurs ordinateurs. Dans chaque cas, le journal indique que toutes les images ont été traitées mais me donne l'erreur d'exécution suivante.<\/P> "Une erreur d'exécution s'est produite : Erreur lors de la recherche de la transformation de WGS_1984+WGS_1984(GXYZ 4978 PROJ 0 GEOG 4326 VERT 115700 ) vers GCS_WGS_1984+EGM96_Geoid(GXYZ 0 PROJ 0 GEOG 4326 VERT 5773 ) : Aucune transformation verticale trouvée<\/EM><\/P>LA GÉNÉRATION DU MAILLAGE 3D a échoué"<\/EM><\/P>J'ai utilisé des GCPs et même ajusté le système de coordonnées du projet pour correspondre au système de coordonnées de l'image afin qu'aucune transformation ne soit nécessaire, mais j'ai toujours eu l'erreur et aucun maillage. <\/P>Des suggestions ? <\/P> <\/DIV> <\/P> <\/P>

Hi @StevenJacobus,

I had a flight from New York state that I tried processing in those coordinate systems as a general test. A transformation is automatically applied if you have the ArcGIS Coordinate system data installed. The processing completed with no errors for the 3D mesh generation. I wasn’t using any GCPs in my test, have you tested without the GCPs and received the same behavior?

I'd like to see your data to help troubleshoot this faster. If you are open to sharing the images and GCPs, please let me know. You can email me (mbarker@esri.com) and I will get a shared folder going.

Otherwise, please send the processing report from the project and a new d2m.log with the logging level set to debug.

Thank you,
Mark

For the image coordinate system I was using WGS 1984 for the xy and EGM96 Geoid for the z. I also tried WGS 1984 for the z since that was the default in older versions of D2M. For the Project Coordinate system I usually try for the NJ State Plane NAD 1983 StatePlane New Jersey FIPS 2900 feet and NAVD88 (ftUS), but I have tried other systems to try and get a result. I have gotten Transformations applied and when I match the coordinate systems I have gotten the message that no transformation is required but if I ask for a 3d textured Mesh I get the same runtime error in the processing log referring to the transformation I still can't find.

I attached the latest D2M log

D2M.log

Hi @StevenJacobus ,

I had a look at the coordinate systems that you appear to be using for your projects and there are valid transformations, even without having the ArcGIS Coordinate System data installed. When you look at the processing options coordinate system section do you see a transformation being applied?

Also are you able to share the processing log and report from one of the projects? If so, include the d2m.log (C:\Users\<your username>\AppData\Local\Drone2Map\log\D2M.log)

Thank you,
Mark
