ReCap Photo, "Project failed with an unknown error" - can provide image files

[Haider_of_Sweden]

I do have not much more information to share other than that I got an error message 

Because of the lack of more clues, it might be best if Autodesk took a look at this.

I can submit this case to the Autodesk Partner Page, but thought it would be more useful for everyone to take part in the problem and solution here at the user forums.

Basically, this is what I got

Some information

- the project is Aerial, and it has no GPS location, and hence will not be geolocated, which is fine. The reason I choose Aerial is the 300 photo limit on "Object" projects. I wanted to try out both, to compare the model quality.

- The images are rotated if that could be causing some problems. I have had success with rotated photos, so I did not bother to rotate them correctly for this project. But please let me know if there is a best-practice

@barmanr - I saw you support similar posts before. I pm:ed you a link with the dataset.

Hi @Haider_of_Sweden ,

For Aerial, the scenario is to have GPS for the images as the bounding box is determined via the GPS locations and this also affects the cropping of the scene. For Objects with No GPS, the algo is different hence Object workflow must be used.

Now with aerial and no GPS, you should still get a result actually if you are using Nadir/Oblique drone images (Images for survey).

Also thanks for the link. I took a look at the images and this set is purely for Object workflow using handheld cameras and not drones. Aerial is focused purely on Drone images for survey.

Thanking You.

Warmest Regards,

The problem is that ReCaps Object mode has a 300-picture limit while the Aerial has a higher limit and that is why I wanted to use Aerial.

The photos could have been taken with a drone, no matter if the target was furniture or a house, right?

Can you see, from your end, what was the reason caused the error?

Is there any "generic" coordinate system I try to see if this would work?

Hi @Haider_of_Sweden ,

Most likely the cropping errored out. Aerial workflow, even though it has a higher limit, is not built for indoor scenes or furniture. Even if it is a building it could go Aerial or Object. Using a camera on a stand and going around the building would be suited for Object. If you fly a drone with the camera straight top down, then well suited for Aerial.

Could you PM me the name of your project? Let me dig out why it errored.

To the question on CS, Yes ReCap Photo does allow an XYZ system. SO if you can roughly measure out points on your scene and give relative coordinates to those based on a fixed origin point, it could work.

Thanking You.

Hello again @barmanr 

This time, it did work-ish. I can see that the algorithm seems different as if it was in fact a  drone dataset. Points were floating in midair as if they were leaves and stuff usually.

Anyway - I sent you PM so you can take a look and share with us some insight from under the hood of ReCap

Not that this is a perfect answer or solution, but it appears that once I set the target coordinate system to BPCNC it seems to work.

The whole thing was a test to compare whether or not Aerial could provide a better image, since it supports more than 300 photos (photo limit on Object mode)

It worked, but the quality however wasn't good.

Here is the result using Aerial and 600 images:

Here is the result using Object and 300 images

thank you @barmanr for checking out the scan status at the backend.
