General / Re: Equidistant vs Equisolid Fisheye?

« on: January 04, 2026, 12:52:55 PM »

Equisolid and equidistant are different planar projections of points on a sphere. While the former tries to keep areas undistorted, the later keeps distances to the center of the image equivalent to distances on the sphere. A fisheye lenses can be designed to counteract the inherent distortion of a planar projection of a spherical image aimed to mimic one of these projections. Rectilinear projection is imposible if FOV is equal to 180 because points on the extremes would be projected parallel to the image plane towards the infinity.
I haven’t seen any fisheye lens vendor quantifying the lens with this respect, so it’s a bit unclear for me as well why Agi has found it necessary to add this distinction.

General / Re: Allign Scans and Fotos

Hi Dieter: I've found a simple way.You can place, by eye and without worrying too much about where, three or more non-aligned points on one of your scans right after import so they take their absolute coordinates from your referenced scans. Then follow the awkward procedure that is meant to allow Metashape to tie photos and scans.
After that, check on the three points and update transform. All the chunk will turn back to the original global position.
It works, at least it is an easy escape from the situation to which the recommended procedure leads, which involves disregarding the georeferencing work of the scan as well as the very precise leveling constrained by the inclination sensors inside of your scanner.

General / Minimal inputs for global transform

« on: November 12, 2025, 07:57:54 PM »

what if
One single reference point could be used to translate a chunk to a given coordinates keeping scale and angles as they are.
Two reference points could be used to translate and scale keeping angles about x and y while rotating about z
wouldn't it be useful for many of you?
what if the trackball could be constrained to work with the Z always vertical for referenced chunks (similar to the terrain mode but in a more standard way). When the Z axis is tied to gravity (most of cases) one wants vertical objects to stay vertical

Bug Reports / Re: I can't edit reference source values cells

« on: November 12, 2025, 04:53:07 AM »

  yes F2, sorry, the bug is in my memory. I must have known this some day in the past but I had forgotten because I rarely edit camera coordinares one by one; this is something most of us do by importing a file. Thanks for reminding me and again I'm sorry.
Regarding the command that's been taken one click further, I admit that it's not so bad if I have a free hand for the keyboard shortcut.
That said, is it too much to ask for a method to make easy to transfer user settings from one computer to another, saved in a dedicated file?

Bug Reports / I can't edit reference source values cells

« on: November 10, 2025, 12:29:37 AM »

Hello:
Quite strangely, since some day I cannot tell when, it has started to be impossible to edit source values in the reference panel table as always by doble click on the cell one wants to edit. So now I need to right click and choose modify, then choose easting, etc... that's painfully slower, as much as I find it has become slower to change orthomosaic photo assignments. Please agisoft stop moving tools if any change adds one o more clics unnecessarily.
Instead of making changes no one is asking for, make the interface improvements that users have been requesting for years: a polygon selection tool, a cursor icon that corresponds to the current tool, etc.

General / Re: Developing Terrestrial SFM Workflow

« on: October 20, 2025, 10:45:27 PM »

Drone imagery comes with geotags and that provides Metashape with a good hint to guess how images overlap their neighbors and saves a lot of useless matching attempts. If your terrestrial images are geotagged and have similar overlap as you aerials, times should be similar. if not, that's possibly the reason for the delay. Use high and not ultrahigh for alignment, and let default keypoint/tiepoint limits unless you know you have a reason to increase or decrease them. They are very well tested and found tobe the ideal compromise between computational cost and success.
Regards.

Your license is tied to your machine, so you can run multiple instances in your computer and multiple versions too with a single license.

Feature Requests / Back face darken in orthomosaic.

« on: August 19, 2025, 09:12:38 PM »

I find truely disapointing not being possible to notice when a face is showing its back side to othomosaic. It is necessary and in my opinion more useful than  the existing back face culling option.
Also it woulf be nice an option to highlight the line of intersection between the bounding box and the mesh.

General / Re: Surface from polygon shape

« on: July 21, 2025, 05:22:54 PM »

If you mean a mesh surface built on tie points inside a given shape this is my suggestion:
Build mesh on all the tie points, draw the polygon you want to use and make it the outer boundary type. Than duplicate the mesh checking trim with boundary shape.
I hope it works for you.

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.

« 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.
