Feature Requests / Add UNDO support for accidently deselected selections
« on: February 01, 2022, 09:22:39 PM »
Sometimes I use the selection tools on a mesh, creating a quite complicated selection using SHIFT and CTRL keys. But if I accidently do not press either of the keys, all the selection gets lost and I need to start again. UNDO does not work in this case. Can you please change it? So next time I accidently deselect what I have spent 20 minutes on selecting, I will just undo deselection and continue selecting.

I use intelligent scissors a lot and I have a high DPI screen. So the points created with the tool are very small. It does not affect the process so much, but when I want to close the poligon, I actually need to zoom in a few times and it is still difficult to click exactly where the starting point is. If the points were bigger or it was possiible to click near the point to auto close, it would be so much easier.

Also, the auto close option should be available in the right click menu. So every time I wanted to close the selection created with the tool, I would just use the option auto-close and Metashape would just connect the last point with the first a straight line, even if they were far apart. So much easier.

I use the magic wand tool for maskig a lot. And since the beginning, to change the tolerance of the tool, I have to go to a separate tool/window, set the new value and come back to using maric wand. Can you please make the tolerance setting available every time the wand is used, so I can easily readjust the tolerance each time I need it?

I had 1.8.0 very briefly. I started processing one of my bigger model and it kept crashing. Never got to the stage of texturing. So I downgraded to 1.7.6 to be able to work on it.

Quite often, when processing textures, I end up with some low quality patches. It happens only because Metashape chooses a more distant photograph to use in that particular spot. Could you pleas add a tickbox to texture generation box that would prioritise the closest and therefore most detailed photos. It would save a lot of manual work I need to do with disabling the farthest photos at texture generating stage.

Bug Reports / Standard 1.8 crashes windows during mesh generation
« on: January 19, 2022, 11:26:57 PM »

I tried to proces a mesh(from depth maps) under Standard 1.8 in a project that I had processed multiple times under earlier versions. The project has 3652 photos aligned. It crashed windows twice exactly at the same stage of the process.

The full log from that session is attached as a ZIP file, because it is over 5MB. The log from previous session is exactly the same. Crash happens during part #4/7.

There is no trace of a problem in Windows event log and at both times I was not looking at the screen when it happened. I just came back after an hour and my computer has already rebooted.

So I unistalled 1.8 and re-installed 1.7.5 and run the same process. The problem did not occur.

I have Nvidia 3070 and 32GB of RAM. I have successfully used this setup for projects that have 45000+ photos under 1.7.5 and earlier vesrions. So it is not the matter of my computer or the number of photos. It is just some issue with version 1.8. I cannot be more precise, because there is no trace what went wrong.

General / Re: Processing a massive underwater photoset without GPS
« on: October 23, 2021, 04:26:33 PM »
Thank you guys for your lengthy responses.

I have been doind underwater photogrammetry for several years now and processing 20 000 - 30 000 photos in one chunk is not new to me. I know how generic preselection works and how to scan my underwater sites. I already have my workflows for my very precise underwater work and I really know what I am doing with almost all the options I use... Apart from the Reference preselection SEQUENTIAL and ESTIMATED that are not really described in detail in the manual. Furthermore, the way these work have changed over the last few years, so I really need information from someone who is sure.

The difference between this project and my previous big projects is that I will probably end up with around 120 000 photos and I want to find an optimal way before I just click "Generic Preselection" and "Reference preselection" and then wait for a week to see what happens. Also, gathering photos will take a while and I need to be able to quickly do some preview alignments to double check the coverage.

So my questions are very specific and technical and only about the alignment parameters. Let me rephrase them then:

Does anyone know how Reference Preselection Sequential and Estimated work without GPS and how they work in combination with Generic preselection?
Which one is applied first?

If Generic is as second, then does it take into consideration pairs already found by Reference preselection or does it do its thing to all photos anyway?
If does take into consideration the pairs found by reference preselection, what happens then? Does it only use generic for photos without pairs?

I really need to understand the algorytms behind each of these options and their combination. Anyone?

General / Processing a massive underwater photoset without GPS
« on: October 23, 2021, 09:57:39 AM »

I am processing a massive underwater photoset (so far 50 000 photos) and I keep taking 10 000 photos every day. There is no GPS data and I am looking for a solution to speed up the matching part of the process. Therefore, I need to understand how each of the following work.

1. Reference preselection set to sequential + generic preselection. What is it going to do? Will the program do the sequential preselection first and only the photos that have no pair will have generic preselection applied? Or will it do the generic preselection for all photos, finds all matches and then also add sequential preselection on top to find even more matches and actually extend the length of the process?

2. Reference preselection set to seqential while every second photo disabled, so only half of the photos are being aligned. Provided that they will align somehow... Then I enable the other half of the photos and what are my options then? Sequential again? Or perhaps Estimated? With generic preselection on or off?

Any other ideas how to match only the photos that should be matched?

General / Re: Agisoft Metashape 1.7.0 pre-release
« on: January 30, 2021, 08:55:00 PM »
In the changelog I found this a few build back: "Added Save camera track option for Sketchfab uploads." But for some reason I do not see this option under Metashape Standard 1.7.1.

Anyway, I always save a 3d file manually and upload it to Sketchfab. How can I then save and .fbx file with animation, so sketchfab can use the camera track as animation?

Bug Reports / 1.7.1 Mesh colour disappears when closing holes
« on: January 29, 2021, 12:07:11 AM »
Now when I now close holes on a coloured mesh, the colours disapear and I have to reprocess them again. It used to close the hole and the new faces had colours from neighbourhood triangles. But now all colours are gone and I need to colorize again.

Bug Reports / Re: Avi file wrong duration when exporting animation in 4K
« on: January 28, 2021, 08:56:38 PM »

The noise only happens when I process some models, only those with many detailed 4096px textures, like buildings. When the camera comes closer to one section of a model and the texture becomes bigger, the noise disappears.

I have now ticked "Enable mipmap generation" under Advanced preferences and there is no more noise in Full HD video, but everything seems less detailed. In 4K also no more noise (there actually was some small noise before) and also everything bit less detailed, but acceptable.

All of them are from a 2-minute animation and are 2 minutes long when played under windows built in player.

1. Full HD 60fps is 4.6 GB (seen as 2 sec long)
2. Full HD 30fps is 2.3 GB (seen as 16 sec long)
3. 4K 60ps is 15.2 GB (seen as 1 sec long)

I have run several tests and the display length of the videos is always the same.

I have also noticed that if I now render a FULL HD video on my 4k system, eaach frame is poorly downscaled, so I get weird noise on my full HD videos. Rendering in 4k gives much better result, but some small noise is still there, like there was incorrect anti-aliasing setting.

I rendered the same video a year ago in Full HD 60fps and there was no problem with it. The displayed length is 2 minutes and the file size is 3.39 GB. There is no noise on the old video, only on the new ones.

It looks like it does not work in Full HD either. When I render at 60 FPS, I get 15-second videos that play correctly under Windows built in player but every other program sees them as 15-second videos. When I render Full HD at 30 frames, my video shows as 30-sec-long. I've tried now with 1.7.1 and the result is the same.

I used to be able to export animations as videos in Full HD.

I keep trying with a 2-minute long animation  and each time the result is different, but it does depend on resolution and framerate. It shows  as 1- to 30- sec long, but the actual content of each file when played underwindows is always 2 min, as it should and the stream looks good. But since only this one player sees the actual length of the stream, I cannot work with the video or convert it.

When played under VLC Player, it shows some kind of index error and goes into a loop of fixing it. All I see is progress bar there and once it gets to 100%, it restarts the process, so I never actually see the video there.

Feature Requests / Lock photos/jobs/console window location
« on: January 27, 2021, 06:17:02 PM »
It would  be great to have a small paddlock icon on the photos/jobs/console window which would allow me for locking the windows in place as they are, so it would be impossible to acidently move them when masking photos.

Bug Reports / Avi file wrong duration when exporting animation in 4K
« on: January 27, 2021, 05:54:27 PM »
There is a problem in Metashape Standard version 1.66 (and probably 1.7.1, as there is no mention in the changelog about it) with generating AVI files in 4K. In 1080 I can easily export 2-minute MJPEG videos at 60 fps, but when I switch to 4K 60 fps I end up with a 15 GB AVI video that every program sees as 1 second long and it is impossible to convert. But the correct video stream is there and it plays normally on the build in Windows 10 player. It just has wrong duration and every converter stops converting after the first second.
