I thought I would bump this because I have the exact same question.

General / Re: Masking transparent parts of images
« Last post by jinjamu on March 22, 2019, 08:25:09 AM »
OK I understand. 

So is it correct to say that when a "transparent texture" is encountered in a photo, which matches a mesh surface, then this is textured as white?  (Please excuse my possibly clumsy use of terminology)

Hello John,

Texturing stage does not alter the mesh surface. If you need to correct the polygonal surface itself, you need to rebuild the mesh basing on the masked images.

General / Orthophoto shifts from GCPs when exported to ArcMap
« Last post by rafaeltarantino on March 22, 2019, 01:13:29 AM »
I'm new on UAV image processing and I'm having an issue when I export an orthophoto from Metashape and open it in ArcMap (arcmap_print.jpg), the image shifts from the GCPs. However the DEM does not shifts and has good match to the GCP. The coordinate system is SIRGAS2000 UTM Zone 23S. Someone had the same issue and found out a solution?

Hi Alexey. 

I did as you suggested, however the masked out pieces are ending up as white in the textured model. The masking worked 100%, as I mentioned before, and my hope was that the polygons generated from the masked out areas would simply disappear. 

I generated the PNGs with the transparencies from a program called IMBATCH.  I did the alignment with JPGs and Photoscan had no problem to accept PNGs instead.

Thanks for any advice

General / Merging Everything
« Last post by jazzyj on March 21, 2019, 08:22:51 PM »
I created a model and forgot to include some of the photos.  All photos were take with the same drone/camera at the same time. I built the point cloud, dem, and orthomosaic. I want to avoid reprocessing everything.  I've added the additional photos as a second chunk and am aligning them.  Should I merge the aligned chunks and then reprocess the point cloud, dem and ortho, or can I just process the point cloud for the second chunk then merge everything into one and generate the new dem and ortho or can I even just process the dem and otho for chunk 2 and then merge everything together?

Thank you I will try that!

Hello r.herberth,

I've checked the provided log, the issue occurred within the mesh generation procedure due to the very high density of the result. We are actually working on improvement of the behavior in such conditions, but it would be likely not a short-term solution, so to avoid the problem I can suggest to use lower quality setting for the depth generation (High instead of Ultra, for example) or try to generate the model in several blocks, if Ultra quality is required. The area of reconstruction can be limited by the bounding box.

Hello Jason,

There's an example on the page 57 of Metashape Pro manual:
https://www.agisoft.com/pdf/metashape-pro_1_5_en.pdf

The minimal format requires image file name with extension and XYZ coordinates. Each line represent only single image (camera).
