General / Re: Problem: DNG and TIFF inputs create flat scene on reconstruction

« on: June 11, 2025, 08:05:27 PM »

You can grab suitable parameters form a successful project based on corresponding jpgs. just goto tools-camera calibration then open the adjusted params tab and save as...
leater in the project with tiffs right after opening cameras open the same dialogue and import this file in the initials tab.
Then align photos as usual. These initials (aka a priori) values will play the role of flexible constraint and will likely prevent the flattening you are experiencing now.
But I would rather find the reason for the lack or initials. If your tiff files have no focal lenght and sensor size in the exifs, it might be because you are using wrong metadata handling setting during development.

Check camera calibration parameters and if they are null, enter reasonable values.

General / Re: Help in identifying fiducial position Fairchild camera

« on: June 04, 2025, 09:52:33 PM »

I think Fairchild fiducials used to be a white small dot inside the outer black frame in the center of each side. The additional dents closer to the corners are intended for srinkage control.

General / Re: Setting View to specific numerical axis

« on: May 20, 2025, 08:30:23 PM »

It would be nice but unfortunately there isn't a tool for this in the interface.

Views saving as much as region and clipping boxes saving  is something I have requested a couple of times, but it seems it is not so important for the developers.

However, what you need is something that can be done by means of scripts and it would be easy... If you know how to.

Also, if the desired angle is an integer multiple of 15º, then you can rotate in 15º steps from a standard view using the num keys with 2, 4, 6 and 8 keys. This is the closest to a repeatable non standard view that you can find built in.

General / Re: point cloud precission degraded during export

Thanks Alexey: But why do I get more precission (apparently) inside Metashape when I draw or pin points on the same dense cloud. where do milimeters and sub-mm come from in this case?

General / point cloud precission degraded during export

« on: May 17, 2025, 03:17:26 PM »

Here is what I find.
Build a dense cloud within Metashape and pick a random collection of points. (I have done by means of the point drawing tool and then exported shape layer as survey point)
what I get is a list of points with coordinates like this. I have forced 4 decimal places on purpose.

all milimetres have gone! Why?

Same happens within Global Mapper or any program, so is it maybe Metashape degrading the point cloud accuracy during export?

Feature Requests / Obect vs terrain modes

« on: May 16, 2025, 09:51:36 PM »

I'll be frank. There are a number of things about the way we navigate in the model view that truly demonstrate how pathologically lazy our Agisoft heroes are when it comes to improve the GUI user experience.

We've spent years and years getting used to a stone in our shoe, but the callus on my foot hasn't made me forget about that damn stone.
Object mode is the only one I use because switching from it to terrain mode is so much painful as telling a violinist to switch the bow and violin to play Beethoven and use the other mode to play Vivaldi. They aren't two modes that can coexist in the same standard brain. IMHO

Since mostly all users I know prefer object mode, couldn't a toggle be added so that in referenced models, all movements could be forced to always keep Z up, but without changing anything else in that mode?

Is there anyone here, leaving aside those who feel comfortable watching the Tower of Pisa, who likes not being able to prevent the view from rolling to one side or the other when using free rotation without  fighting to pick the trackball's equator?

Only if the model isn't referenced, or hasn't yet been transformed into a world with Z up, should the current mode's crazy rotation be the default. This current "zero gravity" mode may be desirable in very specific cases and yes, keep it for such very specific operations, but for my taste, it's exceptional, not universal.

But if what I suggest doesn't seem like a sensible request, why not just add special screen zones near the window margins  that can be made visible and active by holding certain key to constrain the rotations of the current mode to rotations about camera view axis? Something like this:


Best regards.

Feature Requests / Re: Smart Marker detections by Surveyed GCP Location

« on: May 11, 2025, 10:51:14 PM »

Hi Ben: The feature you want would only work well if absolute image geo-reference is good enough, and this is often not the case for elevations.  However, I can agree with you it could work fine after 3 markers have been pinned twice and the global transform is updated.

General / Filter photos by shape

« on: April 14, 2025, 10:59:45 AM »

Filter photos by shape works only for the vertices of the given shape. There should be an option to select all the photos that can see the shape along the edges and optionally also inside a closed shape.

Agisoft, please, give us a proper polygon selection tool, (or at least let us use any closed shape for selections as serves for dense points), you can't keep ignoring this simple tool requested for years, freehand is fast but is very imprecise.
Let us select photos by polygon, select triangles by polygon, select tie points by polygon, PLEASE

General / Re: Points in point cloud disappear when zooming in and out

« on: March 29, 2025, 01:02:07 AM »

Yes olihar. The clipping plane. One of the weirdest and hardly useful features… I would almost call it a bug. Or perhaps is something our Agi-heroes left unfinished with a plan in mind, but they forgot the actual plan. Instead of an uncontrollable front clipping plan, wouldn’t you love to have a proper clipping box? you can save and manage them and use one or more to clip view and eventually exports without touching the region. Would you second that?

Sbond, a double click on the point cloud or model will fix the annoyance.

General / Re: Colorize Points Inside a Polygon ?

« on: March 23, 2025, 01:42:37 AM »

Hi José,
From a surveyor’s perspective, drawing freehand shapes in an image editor feels a bit impractical — each color usually represents a calculated volume, real distances, properly surveyed lines, and measurable quantities.

Well, you can rasterize vector layers on Global Mapper, for example, and then export colorise the mesh vertices from orthomosaic. ( I’m a land surveyor too, by the way, and I find freehand pretty practical quite often)

General / Re: Colorize Points Inside a Polygon ?

« on: March 21, 2025, 08:59:35 PM »

Hi folks: There is an easy trick. Export orthomosaic, use your favourite image editor and add tint to the areas you want to highlight/colorize. Then re-import in Metashape.
After that you can colorize vertices using your fancy orthomosaic.



Best regards
