'Create Orthomosaic' est coché dans les Options de Traitement, mais aucun n'est réellement créé

<\/HEAD>

Bonjour à tous,<\/P>

<\/P>

J'utilise une version d'essai de d2m et j'ai du mal à faire créer mon orthomosaïque. 'Create Orthomosaic' et 'Merge Tiles' sont cochés dans les options de traitement, je peux voir le traitement dans le Journal de Traitement sans aucune erreur, mais aucun ortho n'est réellement ajouté au projet, ni trouvé dans mon dossier de projet.<\/P>

<\/P>

Le rapport de traitement montre un aperçu de tout comme il devrait être, y compris l'ortho, mais seuls le DSM et le DTM sont effectivement créés et ajoutés au projet.<\/P>

<\/P>

Au cas où cela aiderait :<\/P>

- Je fonctionne sur Drone2Map 1.3.1.226<\/P>

- Le projet contient 133 images (1,11 Go)<\/P>

- Les images ont été prises par un Mavic Air, et le plan de vol a été élaboré avec Pix4D Capture<\/P>

- La GSD moyenne est de 2,04 cm<\/P>

<\/P>

Quelqu'un a-t-il déjà rencontré ce problème / sait comment le résoudre ?<\/P>

<\/P>

Merci !<\/P><\/BODY><\/HTML>

After working with ESRI tech support, the (correct) conclusion was made that our UAV needed to be re-calibrated after imagery from other drones created an orthomosaic and everything else just fine.

Cody, thanks for looking into my issue!

I've attached the logs. There are 747 images in this project. The project took 2 days to compile everything and stitch things together. The drone that was used to fly is a DJI Inspire 2. The computer doing the work is dedicated to Drone2Map and is a Dell Optiplex 7040, i7-6700 CPU @3.40GHz with 16GB of RAM running Windows 7.

I've started a new project using only the first 399 images. It is currently at 56%.

Hey April,

The Drone2Map update 1.3.2 fixed my issue completely and I am able to create Orthomosaics using images from a DJI Mavic Air without any issue. As Cody has noted above this does sound like a different issue. Hopefully separating the images into two sub projects proves successful.

Cheers,

Bryan

As noted above, we had a known bug that could cause this, but we believed it had been fixed in 1.3.2. If you're getting tiles in the orthomosaic_tiles folder, this sounds like a different problem.

How big is your project in terms of # of images? If it's more than ~1500-2000 photos, you may be having memory problems, so may need to split it into two subprojects - ensure some images overlap (~2 flightlines) and include ground control in the overlap region.

Did the processing complete normally and declare "success"? If you have ArcGIS Pro (or ArcMap), you should be able to load the tiles into a mosaic dataset and review them - are there tiles missing?

Best would be if you can send us the log file - Go to Processing Options/Resources and find the link to the log.

I have experienced this same problem this week with some drone imagery. I am using Drone2Map version 1.3.2.232.

After 2 days of processing, I have a folder full of ortho tiles that I can individually add, but no full orthomosaic. The processing report shows an image of an orthomosaic and I don't see any major issues with the image in the pdf...

Is there a chance that the orthomosaic was going to be too large? I feel like I've done a similarly sized area before, but I'll try a portion of this project and see how the process works.

Hi everyone

First, I apologize for the slow response on this. The good news is we have found the problem, and we have a fix for you.

We have found a bug that relates to newer cameras and an outdated copy of the camera database. This has been fixed with Drone2Map version 1.3.2 which will be available on or before November 14. We'll have a blog here (and your software will notify you) when the new version is available.

If any of you are working on urgent projects and cannot wait until next week, we can give you a workaround that involves manually replacing system files. Since that is a bit risky, we’d recommend you wait for the new version, but if anyone on this thread needs the workaround urgently, email us at drone2map@esri.com and we'll send you the steps to fix this problem.

Thanks for your patience.

Hey Angela,

I was not able to resolve the issue in Drone2Map. I was able to find a workaround by using ArcGIS Pro. If you have the image analyst extension in ArcGIS Pro then you can use it to create an imagery workspace that allows you to go step by step through creating the Orthomosaic. Hope that helps.

AngelaGruber

I'm having the same issue. Could you elaborate on what the setting is that needs to be changed on the UAV?

Thank you!

Hey Mark,

I am experiencing the exact same behavior with Drone2Map when using my Mavic Air. Could you provide any more details about what specifically you had to configure on the drone. Was this configuration done in the DJI Go App or on the PIX4D software?

No orthos to be seen for rapid or more intensive projects, even after a full reinstall. I had our IT guy take a look too, and it doesn't look like anything is getting blocked by the firewall / server security settings.

TrentReeder

Hmmm..that is odd. Are you missing orthos after a Rapid project as well? You may try uninstall/reinstall process. I had this happen to me on an older D2M release, but I haven't seen the issue since.

MarkTryon2

This is what I'm getting - Everything looks the same as yours, just without the actual ortho files. It does create the "ortho_tiles" folder, but it's totally empty.

TrentReeder

Interesting. Usually it's the other way around for me with the elevation raster not coming through...

Here's a screen shot of what is normally in your project's "products" folder:
