General / Re: RTK Positioning accuracy with Mavic 3E

This is my point exactly, this will not allow others to participate reading or commenting. Stating using a translator on a forum English is used is pretty rude.

You saw that winking smily at the end of my sentence?
Do I really need to explain this smily's statement to you?

Just for your information: All my statements here come 1:1 from the Google Translater, otherwise I couldn't write anything here at all, because my English is too bad for that.

And that's all there is to it from my side.

A little tip, there is such a function in many web browsers, which is called translator  

But I'm fine with it. To the webmaster: Please move this post to "other languages"

Wenn ihr ansonsten im Metashape alles richtig gemacht habt (Überlappung usw.) dann bin ich mit meinem Latein am Ende

Sieht so in Ordnung aus, wie hast du die Kontrollen am Boden bestimmt? Irgendwoher musst du ja wissen, dass es -1,5 Meter sind.

Die Mavic liefert ellipsoidische Höhen, die musst du noch auf das Geoid reduzieren, dann passt es.

Mittlerweile habe ich auch mal ein paar Flüge mit PPK nachgerechnet und das Ergebnis ist niederschmetternd. Wer, wie wir, in schlechten Umgebungsbedingungen fliegt (Häuserschluchten), sollte den RTK Koordinaten nicht vertrauen, da gibt es Abweichungen bis zu 15 cm.

Wir berechnen mittlerweile alles nur noch mit PPK, seitdem stimmen auch die Ergebnisse.

Bug Reports / Re: Masks for laserscans not working

« on: March 13, 2024, 07:37:59 PM »

Hello,
I am of the opinion that when generating the dense point cloud, the masks in the laser scans do not work. According to the manual and also according to this thread, these should work by now! Can anyone confirm this for me? Tested with version 2.1.0.

General / Re: GPU GTX 3060 is low on memory at 12 GB

Thanks for the tip, that's an interesting aspect with network processing.

However, when I look at the protocols, as far as I can tell, the non-network version of my application (wooden tower) does the same thing as the network version. Nodes are formed, which are then processed one after the other.

In the end, it didn't work for me, the error with the too low memory came after 2h 40min

It is a 25 meter high wooden tower, which was measured from above with 1229 photos and from below with 25 laser scans. The tower is to be demolished and rebuilt later.

The photos have a resolution of 5280*3956, the scans vary between 42 million and 120 million points in 360 degrees. I only scanned sections of the tower and also cropped the point cloud in the metashape. The resolution of the dots varies between 2 mill and 120 mill points.

Yes, that's how I did it in the end, I split the model into 15 parts and then put the individual parts back together, that was a big effort. At some point, I have to finish my work;) But it must be possible to split such calculations into smaller parts so that this does not happen.
Elsewhere here in the forum I have read that the standard of free space of the GPU was then simply lowered by programming to make a calculation, my question is whether this would also be possible at this point?

Hello Alexey, we urgently need a solution here, because we have to hand in projects, but the error message prevents this.

Is a beta available?

No matter what I try, Metashape doesn't manage to compute the mesh with high resolution in a project with photos and laser scans.

See error message at the end of the log:
2024-02-23 11:25:10 device NVIDIA GeForce RTX 3060 ignored because it has 11020/12287 MB available, but 11489 MB required.

What can I do?

Tja, was soll ich sagen, die Höhen der Mavic sind in der Tat um die 4-5 cm zu hoch, ich kann mir das nicht erklären. Getestet mit 3 unterschiedlichen Befliegungen, die GCP wurden mit RTK eines anderen GPS überprüft. Immer die gleiche Abweichung. Bin etwas ratlos, ehrlich gesagt.

Bug Reports / Wrong Coordinates in Laserscan Export as E57

« on: February 06, 2024, 07:47:56 PM »

If I export a laser scan aligned in metashape as an e57 file, which coordinates are then output as the scan location coordinates of the laser scan?

The newly calculated values should then also be output in the E57 File.

At the moment, the height is always output as 0.
