General / Exporting Contours (Seamlines) from side-views (not top-down)
« on: December 09, 2022, 02:55:30 PM »
As a short explanation: I am working on several walls and have their 3D models with accurate GPS-data and everything aligned and working well. Now I would greatly benefit from generating seamlines of single parts those walls surfaces (facades) from the Orthomosaics/DEMs. What I did was to generate DEMs from the viewpoints I wanted and then from that I am generating contours.
Those viewpoints are all from the sides of the Walls, facing their facades. Not from the Top (The top ones (nadir) are separate and all working perfectly fine, my problems must have something to do with the side-views of the facades)
Now three things I don’t understand:
1. (and most important) When exporting the shapes (Contours) into any other format (shapefiles or dxf), the view on those countours seems to shift (along the x-y-axis I think) and is unreadable.
2. The contours are visible on all orthomosaics/DEMs and not just on the one I generated them on. Which leads to wrong contours on the other mosaics in the same chunk.
3. While the whole project has always been in a specific EPSG (5253, which is what we use on our GCPs in that region), the orthomosaics and DEMs from the side-views of my walls are shown in a different coordinate system (EPSG 5250) and I have no idea why. (This last point doesn’t bother me too much though, since the exports are aligning just fine in QGIS)
Any Ideas on what is going on or how I can fix my issues?
I’ll attach some photos from Metashape and QGIS for better understanding.
If you need anything else, please let me know.
I hope anyone has some ideas on what I could try.
Kindest regards,
Nils

General / Re: WGS84 Exports distorted in QGIS
« on: August 17, 2020, 03:42:33 PM »WGS84 is not a good format for planar mapping applications. Usually, maps that go to QGIS in that format appear visually compressed in Y . Things will get worse with higher latitudes. You must use a projected system compatible with the country of your client. Every country have an official coordinate reference system in projected coordinates suited for planar mapping work.
QGIS has an outstanding manager for coordinate output. This way you can plot your map in UTM11N, for instance, but output a coordinate grid in WGS84 without any problem. Pay attention that being UTM11N a planar system and WGS84 a spherical system, the WGS84 grid lines will appear not parallel to the map limits. However this is perfectly normal.
This was exactly what i needed, changing the system did the job, thanks!

Feature Requests / Re: Add Scale bar option during ortophoto export
« on: February 26, 2020, 02:21:43 PM »This is an issue that makes it difficult to work with Metasheep - the inability to produce and export a facade or section with a scale perpendicular to the ground, in an easy and friendly way.
This topic made me work with competing software that provides a theme-friendly solution, even though I prefer to work with MetaShape in any other aspect.
The improvement needed for the problem can be:
1. A function of creating a facade in a desirable direction by marking the cut line, rather than by markers, which greatly complicate the work process.
2. Export of facade or section (one or more) with a scale bar.
3. Export of section Plan with a Scale.
Thanks,
David
Absolutely true, i am constantly asked for exports with those features and my workarounds are annoying and time-consuming. It would be great, if this topic would receive more attention by the Agisoft-Staff.
Nice to hear, that i'm not the only one suffering from this lack of functionality.
Kind regards,
Nils

« on: December 19, 2019, 05:13:46 PM »Hello NilsS,
Can you send the complete output from the Console pane related to the cloud processing start which contains the error?
If the log is sensible (in terms of any paths), you can either remove the sensible paths from it or send it via PM.
Sorry for the really late reply, everything is working fine after two more updates, my bad for not responding, i completely forgot.

I would like to bring this request back up, because i am struggling with the same thing for years. It would be great to have this rather simple feature. My work would be much easier.

Yes, same error code and yes, i'm on the newest Metashape Version.

I am having the same issue here, haven't found a solution so far.
Any one else found out what is going on with that error?
by the way: just picking up the project where it stopped did not do anything, it just caused the same error again.

General / Re: 2D Line Drawing from Photoscan Model
« on: July 26, 2018, 07:16:32 PM »
i think i understand what you are suggesting but for my usage it would be important to decide manually, which areas of the exported orthomosaic should be traced and how those lines should be the be represented on the final 2D drawing (e.g. lines or dashed lines).
So as far as i know, it seems essential to me, to trace the lines manually.

I'd like to pic this topic up again and go a little further into detail concerning the workflow from exporting the orthofoto and drawing the lines in Illustrater/Autocad.
How do you manage to get the exact angle for generating the Orthomosaic considering that creating an Orthomosaic from"Current View" is always a manual setting.
How do you avoid mistakes in your object-alignment before creating the mosaic? Or are there other, more stable export options for redrawing models?
