Bug Reports / Can't select tile size in 1.7 release.

« on: January 17, 2021, 05:45:50 AM »

With the official 1.7 standard release, once every 2-5 times I align photos I get "Can't align tile size" until I restart Agisoft.

GPU: 5700xt + Fury X

CPU: 1800x

Memory: 48GB DDR4

Driver: Initially used 20.12.1, but that driver would randomly restart itself. Thinking that was causing the issue, I downgraded to 20.11.2, the restarts seem to have stopped, but the issue here persists.

This didn't seem to happen with any of the pre-release 1.7 versions I've used. It also happens when doing batches, it stops being able to align photos after completing < 5 chunks, failing the rest.

Log seems to be detecting a duplicate for each GPU but I only have the 2, then when it fails it detects no free memory on the GPUs.

General / What exactly determines which cameras are used for textures?

« on: September 22, 2020, 04:26:59 AM »

I'm looking to improve my textures and I'm wondering how the texture generation works in more detail, and if it makes sense to do an extra set of close up images.

I found a post from 2013 saying that the texture is taken from the photo most parallel to the triangle being textured, which makes sense. (https://www.agisoft.com/forum/index.php?topic=1510.msg7847#msg7847)

But are is there a more complex algorithm in today's MetaShape for choosing photos? IE, two photos have the same angle, would the closer one be more likely to be chosen?

Thanks Alexey. It's usually not a huge deal, they get worse with worse alignment or might not show on the model randomly. Smaller cases can be smoothed out which I usually do anyway before refining. 1.6.2 seems to fix the specific issue of lines.

Fresh run logs attached, still no lines, run twice each.

Yes I restarted and verified the values before running each time. I'll run it again just to be sure. "no tweak" is the one with a space as the value.

Alexey, I've run the mesh generation with depth maps on the version you sent, with and without the tweak. I don't get any lines after running each twice, but the runs without the tweak generate more "erratic" meshes and appear to be not as smooth.


Without the tweak, run twice:

Any progress on reproducing this Alexey?

Alexey, I think the issue is related to using 5700 XT in combination. The lines go away only if the XT is used on it's own or disabled. They come back if XT is used in combination with the Fury X, CPU, or Fury X + CPU.

In one case I ran build mesh on a different image set that had a bad alignment, one section was raised by about 3x more than I usually see. Maybe the values for alignment aren't always the same for XT?

Just for fun, here are the logs for another model. As a zip because it's from a much larger image set.

Still happening for me, the major ones on the turntable stopped(for this image set at least) but they still show up on the model. I've encountered the bug mentioned by Vlad and Mak one time(with a different model) where it looks like low bit depth, but I think this is a different issue.

I've attached the log after rerunning alignment, optimize and mesh.

Sent the email. It's different each time I regenerate the depth maps, sometimes it's just 1 square in a corner, sometimes it's 16 smaller ones, sometimes they appear off axis. They're not always on the subject if I mask out everything, but will almost always be on the turntable if I mask out the subject/background(maybe because it's larger). I forgot to include in the email, I'm using an 1800x, 48 GB ram, 5700 XT + Fury X.

Thanks Alexey, I'll try to put upload it to google drive or something. Fortunately this example has only 52 photos, but it happens with larger sets as well.

In the latest 1.6 version I've noticed for some of my models when generating mesh using depth maps on high, it tends to produce small vertical and horizontal line in the mesh. They can be smoothed out somewhat.

If you imagine an actual checker board, the white and black pairs of squares are slightly different heights, so for a given square, the one diagonally opposite has the same height.

+ What is a good way to attach the project files here?
