Please send us a log file for the tiles that are failing

RE: PROBLEMS IN AEROTRIANGULATION

Hi Felix,

I think I've solved a problem but I found another.

I managed to aerotriangular photos with the option "Vertical Automatic".
Now the photos 125 and 143 appear to be in the correct position.

The model is not georeferenced.

In the next aerotriangulation I used the control points with the option:

(if I used the option "Use control points " then the aerotriangualcion failed.

In the last Aerotriangulation I used the option:

This is the aerotriangulaton report.

Apparently it's all right. (Attached to the report.)

But in reconstruction, some tiles fail. (Failed during photos pairwise matching)

In the tiles that fail, there are currently no control point.

How I can get the full model?

Thank you.

I. Settings

A. Positioning/georeferencing:
- Positioning mode: Use control points for adjustment

B. Main settings:
- Key point density: Normal
- Pair selection mode: Default
- Component construction mode: OnePass

C. Estimation policies:
- Tie points: Compute
- Position: Adjust
- Rotation: Adjust
- Photogroup estimation mode: OnePass
- Focal length: Adjust
- Fisheye focal: AdjustFisheyeFocalSymmetric
- Principal point: Adjust
- Radial distortion: Adjust
- Tangential distortion: Keep
- Fisheye distortion: AdjustFisheyeDistortion_01xx0

Thank you Félix.
You're right.
There is indeed a problem with the GPS tags.

We'll try another dataset.

Thank you very much for your help.

Hi Aisier
You say "When I have only photos without AT, and exported to KML, the photos are positioned correctly in Google Earth",
However, they are not. See the screenshots below:
2 photos (123 and 145) captured above the same area

A view of their relative GPS position before AT in Google Earth:

You can see here that these GPS tags are not correct.
They acquisition pattern may at first look ok in Google Earth but the tags are not correctly linked to photos and we have no idea of how the are wrong (nor how they can be fixed. The problem does not come from ContextCapture but, more likely from the acquisition system.
A workaround could consist of using a "fake" GCP derived from Google Earth (you would need to identify at least 3 GCP and their coordinates in Google earth before using them in ContextCapture for rigid geo-registration) however, this workflow is a bit inaccurate.

Thanks Felix.

But I do not understand what is the problem and the solution.

The problem is the data set?

Or is the program that makes the AT wrong?

When I have only photos without AT, and exported to KML, the photos are positioned correctly in Google Earth. So where the error is in the GPS coordinates?

How I can change corrected GPS tags if they are not correct?
Is there any way to make a correct AT without using the GPS position of the photos? Only control points?

Thank you very much.

Hi Asier,
Thanks for sharing the images. We managed to reproduce the same issue using your dataset. The pose of the cameras after AT is far away from their initial position. We believe the issue comes from the GPS tags of the images. They were, in some way, interchanged or maybe they are just wrong. Because of this the Block-AT is not “correctly” positioned after AT.
The AT is computed independently and adjusted on wrong GPS tags, these GPS tags must be corrected before being used.

Is posible WeTransfer using?

Another way to send files?

Hi, there seems to be no clear explanation for this. Would it be possible for you to share your images with us for checking? I can send you an upload link and details.
