one possibility would be to disable all interior images while making the mesh of the exterior

General / Re: Seamlines re-use
« on: October 27, 2023, 12:16:25 PM »
+1 for a method to do this please.
I often spend a long time manually assigning images only to later realise that I should have done colour correction, or not done it, or added some more photos, or improved the alignment, and then subsequent rebuild of the orthomosaic causes all the shape/image assignments to be lost.
I'm not saying it can't be done currently, but I don't know how.

General / Re: Build Point Cloud
« on: October 27, 2023, 11:44:07 AM »
It seems like Metashape doesn't automatically switch the dense cloud view after building the dense cloud.
You can switch to it by either double clicking the newly created "Point Cloud" in the workspace/chunk explorer bit, or Model -> View Mode -> "Point Cloud - (various options)" or the Point Cloud icon in the toolbar (showing a 3x3 grid of points).
If none of those work then I guess it really didn't do anything, like you say!

General / Re: How to get extrinsics from XML
« on: September 01, 2023, 06:30:24 PM »
Don't know if this helps, but I struggled with the XML format almost 10 years ago and think I came up with something that worked for me, though I haven't returned to it since.
Take a look anyway, and see if this helps:

General / Re: New Depth Map each mesh generation
« on: August 29, 2023, 05:36:04 PM »Is this the way it's suppose to work?
Yes, except building the mesh doesn't require a dense point cloud to be built first. Both the dense point cloud and the mesh are derived directly from depth maps.
The quality you specify in the 'build mesh' dialog corresponds to the resolution of the depth maps so, each time you change the quality setting, new depth maps need to be generated at the appropriate resolution.
I would think that once I've generated the dense point cloud any mesh is going to be a derivative of that and a new depth map shouldn't be required.
If you do need/want both dense point cloud and mesh, then the depth maps for one can be reused for the other, but only if you opt to generate both with the same quality setting.
Furthermore, though I think this goes beyond what you're asking, it is possible to keep depth maps for multiple quality levels, but you have to manually right-click the depth maps in the chunk explorer workspace and uncheck the 'Set as default' option so that they will not be overwritten when you generate at a different quality level. Then when it comes to reusing them to build a mesh or point cloud you have to ensure that you have set the appropriate set of depth maps (for the quality you want to 'build' at) to be default before you can opt to reuse them in the build mesh/build point cloud dialog.

General / Re: Jello effect in Orthomosaic generated for Micasense Altum
« on: August 29, 2023, 04:59:25 PM »
this is all from memory so some of the names/places of things might be a bit off!
right click on the affected part of the orthomosaic and select 'open image' (i think this was available in 1.8.5). then you will see which image was used to generate this part of the orthomosaic. you will probably/hopefully find that for whatever reason it didn't choose the best image for that part, i.e. too far away or at an oblique angle.
to fix it, draw a polygon around the affected area (turning on seamlines can help to see the extent of the area covered by this suboptimal image) and right click on the polygon and choose assign images. then select the image that should have been used. once happy, right click on the orthomosaic in the chunk explorer (i forgot what it's called exactly) and choose regenerate to apply your changes and blend the images together nicely.
if there is no better image to choose from in the 'assign images' window, then either you didn't get a good image of that area, or some of your images are misaligned.

Bug Reports / Re: Details view sort by column
« on: March 30, 2023, 11:40:40 AM »
Sorry, I should have been a bit more rigorous before reporting it as a bug.
Hopefully I'll soon get a chance to pin it down, and try to reproduce it on a smaller project that I can share.

Bug Reports / Details view sort by column
« on: March 29, 2023, 11:10:42 AM »
Metashape Pro 2.01 64 (15986) on Windows 10
I had noticed this in previous versions too and assumed it would get fixed eventually but it appears not yet!
It appears that sorting photos by clicking on the column headers in the photo pane does not work if certain filters have been applied. It seems to be an issue if "filter by point" was used, on either the sparse cloud or mesh, or "filter by marker", but when using "filter by tie points" it does appear to work as expected.
I noticed because I wanted to sort by 'enabled' after filtering photos by a point on the model surface, to then further filter the disabled photos, but they were always still disordered. So then I tried some other columns and experienced the same. It seems like clicking the column header sometimes has no effect on the order, and sometimes it will just reverse the current incorrect order.

Feature Requests / Re: multiple tabs for same data type
« on: November 21, 2022, 02:52:54 PM »
With images you can have multiple tabs (right-click the image in Photos pane and 'Open in New Tab'
Then you can right-click the new image tab and 'Move to Other Tab Group' so you have two images open and visible at once.
It's not perfect but it helps.

Feature Requests / Re: better support for rigid camera rig
« on: October 03, 2022, 04:26:10 PM »+100Another +100 please
Would be great to be able to export the calculated slave offset and import as reference in future projects, rather than have to type all those number in each time!
I'm using a stereo rig for close up handheld scanning and being able to import the camera offsets would allow me to get my scans scaled properly without worrying about markers and scalebars.
Alternatively, being able to select a master camera and create a scalebar between it and the slave would achieve the same thing for me, but this doesn't seem to be supported.
If there is an existing python solution I'd be happy with that, and otherwise I I'll try to figure one out myself!

Camera Calibration / Re: Adaptive camera model or calibration groups
« on: August 01, 2022, 12:25:10 PM »Is there a way to select or sort photos by speed and direction of drone flight so that each group can get different rolling shutter corrections? I can't even find a way to view the metadata that shows speed
I don't think so, except maybe through python scripting, but what might help is that you can select photos using the 3D/Model tab or normal photos pane, and then open the camera calibration window, and any photos that were selected before will now be selected in the list at the bottom of the calibration window, though you may have to scroll down to find them.
Still doesn't help you filter by speed or direction, but it may be easier to identify and select these photos intuitively in the 3D view before you go into camera calibration.

In the lower right of the 'Camera Calibration' window is a list of all the photos in each group. You can select the photos you want to move to a new group, right click and select 'Create Group'.
