Unmatched reconstruction

[jrh87]

Hi,

I am trying to create a 3D model from aerial images. The facade has some trees covering it and, thus, for some areas, the overlapping may be a bit poor. When I push the images to Metashape, the reconstruction returns 2 different misaligned areas (see image below). Is there any issue to fix that? Even if poor overlap may be the issue behind this, other software tools out there are able to consistently generate a good 3D model for the exact same input data, so I would expect Metashape to simiarly overcome this.

Thanks!

Hello jrh87,

You can use Matching Graph feature to check, how well are those alignment parts are connected.

For fixing the problem I would suggest at first to reset alignment for one part and then run Align Selected Cameras for it. If it doesn't help, you can try adding a few markers with projections defined on the images from both sub-sets.

Hello Alexey!

Thanks for your response! If I understand correctly, those are actions to be taken once the problem occured. Since we are looking into an automated workflow, would there be some settings we could pre-configure to avoid such errors?
