Dieter,

here you may find data:

http://gofile.me/4IceV/m3fk4BW4k

As previously mentioned - I did not optimize realignment with markers - they sould have been unchecked when printscreened.

Loking forward to getting any advice from you! Thanks!

I would not pay attention to markers, as they are not mesured by GNSS, they were used just to get some georeference. I should have uncheked them now, for visualisaion.

Hi


I proceeded the re-align and some improvement in dense cloud can be noticed. However, it is sitll not perfect and still not easy for manual clean. Could you look into it again and give me some advice?


In attachement you may find Camera Calibration settings and reference pane. I also attach captured views to show the remaining surface.

Here are the missing pics. This duplicated surface is what I am worried about, as gros error points can be easily deleted by me.

General / Dense cloud wall surface covered by dupliacted, poor cloud
« on: April 27, 2023, 04:34:35 PM »
Hello

I have an issue with dense cloud of a building:

We have flew over renovated XIX-century factory to create a detiled Mesh-model. Flight was planned to obtain just vertical and diagonal photos (no typical horizontal photos with roll and pitch = 0). Just walls, not much of a roofs. During the processing we have discovered, that the general view of a building varies. Some walls look excellent, while other are just poor [Picture 2].

What is more, the poor part of dense cloud turned out to be mostly a duplicated surface [Picture 3, 3a, 3b] , that covered the good one (as you can see in Pic 3a-3b). The whole building looks very bad - but if I cleared the duplicated surface (see the light bricks on Pic 3), it turns out to be perfectly scanned.

While all the walls look similar and there were no difference in flights, what might be a reason and how to get rid of this poor cover? It really affects the mesh texture and tiled model.

Looking forward to any suggestion! Thanks!

Bug Reports / Missing 3d lines on Cameras
« on: January 12, 2022, 06:47:42 PM »
Hello

I have a project where I created DEM. I added 3d lines describing borders of parcels (plot). The point is to update the altitudes and to show borders on pitched cameras, taken along the building site.

However, for no reason some of the lines disappear and appear on neighbouring cameras. First I though, that it was due to "hiding under dem", but as I can see it is not a rule.

How to cope with it so that all the lines appear on cameras? What is the reason for them to disappear?

Looking forward to getting any clue :)

Bug Reports / Re: Invalid shape - polygonal
« on: March 04, 2021, 11:52:35 AM »
Hi

They might have different structure, but the point is that in 1.6 Metashape I am able to set them as boundary, while in 1.7 Metashape this option is greyed out. What is more I cannot calculate the area which makes me think that they are being imported as polyline, not polygon.

I use them to export ortho and dem in parts, but now I cannot do it. KMLs are prepared and exported from QGIS.

What version of Metashape do you use? I downgraded to 1.6.6. and the problem dissapeared.  However, that is not the solution I expected to work out.

Bug Reports / Invalid shape - polygonal
« on: February 25, 2021, 10:58:13 AM »
Hello

For every project I create a kml with several polygonal shapes. Each shape has a description - map section's number. With Metashape 1.6. it was not a problem to import it and use for exporting shapes with proper file name. Now with 1.7. when I import a kml (which by the way in QGIS is imported as polygon), I cannot use it for export - just as if it was a poyline, not polygon. I cannot use it as boundary or measure the area.

In attachement two examples of KML.

I do not want to downgrade to 1.6. Is there any way you could make it work?

Best wishes
Damian

General / Markers eroors before and after selection
« on: May 28, 2020, 10:40:15 AM »
Hello!
The question is about the error [m] value of markers. We have three situations:
1. All markers are selected and the cameras are optimized on them - error on control points is 0,0014 m. (1st attachement - selected_optimized)
2. I unselect all markers - the error on check points raises to 0,0037 mdespite the fact, that i have not optimised the cameras yet. (2nd attachement - unselected_before_optimization)
3. I optimize the camaeras and the error on check points is 0,187 m. (3rd attachement - unselected_optimized)

I understand the change of value between optimisation on selected and deselected markers. I don't understand why there is a value change after deselection and before the optimisation.

Loking forward to reading some explanation.

Usually it works so when orthomosaic or dem selected. Perhaps you set different coordinate systems for each chunk?

Feature Requests / Re: Orthomosaic/DEM export with watermark

I was wondering if request is still considered or it was fully abandoned. Any news?

Feature Requests / Re: Hierachical chunk groups
« on: April 30, 2020, 10:57:05 AM »
It has also one more advantage. We have several projects in which every month we generate trueorthomosaic, digital terrain model and differential models from same construction site. So far I group chunks by date e.g:

2020-03_trueortho_dsm
2020-03_dtm
2020-03-2020-02_difference
2020-04_trueortho_dsm
2020-04_dtm
2020-04-2020-03_difference
etc.

It would be much easier just to see it that way:
+2020-02
-2020-03
     trueortho_dsm
     dtm
     difference
+2020-04
+2020-05

I realize that I can store several dems in one chunk, but it does not satisfy me.  @Alexey, do you plan to intoduce it to us with upcoming upgrade ;) ?

General / Mouse navigation Agisoft 1.6.2
« on: April 02, 2020, 03:56:21 PM »
Hello
I might have a silly question. I updated my Metahspae to 1.6.2. In previous version I cloud move the view by using mouse wheel/right click (with active slection). Now I notced, that both mouse wheel and right click rotate the view. If I want to move the view I need either change to "navigation" or doule-left click to center the view. 
How can I change it back to have a possibilty to move with active selection?

Bug Reports / Height difference when raster transformation
« on: October 07, 2019, 03:45:48 PM »
Hello
I have a project prepared in modern Polish Coordinate System (EPSG 2176), height Kronstad. I would like to export DEM to an old coordinate system (ESPG 2174) with the same height system. Unfortunately the height difference between rasters is around 40m.

In attachements two dems form the same project.
What could be the cause and how can I work it out?

Bug Reports / Re: Classify ground points lasts very long
« on: July 24, 2019, 02:31:32 PM »
Could I get some help with this issue? I am working with another project: Dense cloud 3 400 000 000 points, 7 500 000 tie points, dense cloud clasification after 7 hours 11%, 1 day 18 hours left.
