Hi Dmitry, could give us an explanation of the connected components feature ? Is it a pixel connectivity method ?

I was about to ask the same question!

First observations compared to 1.6:

- Camera alignement is currently (a lot) slower in 1.7 & uses more CPU process during the matching points stage.
- Depth maps génération is also way slower (and uses more CPU process) but also compute depths maps for the whole images no longer being constrained by the bounding box (which is a good thing IMO but not sure if this is the sole reason for the performance decrease)


- Depth maps filtering is way too aggressive (?) now

1.6.5




1.7

Intel i7 6700K

This seems to have the same memory scaling issues that the Refine Mesh option has.

Following errors on a project with 180 photos (61mpix)


EDIT: That being said, when it worked on a smaller project i did notice reduction of noise in the output model. Eager to test more :)

Can you explain:

• Added out-of-core processing support for dense cloud import, colorization and merging.

What does this mean?

That means you are not RAM-bound in processing.

Here are two comparisions between 1.6.5 and 1.7.0

https://ibb.co/TMwNjfd
https://ibb.co/2nJ1Dv0

In one example it does a better job and in the other a worse job. It seems that dubious parts are handled better now.

I think some of the settings/parameters should be exposed so we can fine tune things.

The connected components for image alignment seems to be kind of an auto grouping of pictures, more or less geographicaly homogeneous among each other. It might also only be the tip of the iceberg of this new process. AM spread each picture in three groups, no matter how large is the data set.

Hello,

Whats is the workflow for laser scan import? Agisoft treats indiidual scans as cameras and tries to align them? Result can be seen in attatched image.

Cuda is not active in MacOS. Nvidia GPU's appear as OpenGL. In my case I have two and ony one appears available in the GPU list.

The latest OSX version that supports CUDA is High Sierra 10.13.

That's the OS version that I'm using, precisely because of CUDA, with Two Nvidia 1080 Ti, without any major problem in 1.6.5 (despite a few Cuda crashes once in a while).

Hello,

Hello geodesy,

Current approach is the following:
- prepare scans from terrestrial laser scanner in E57 format;
- open Metashape and use File Menu -> Import -> Import Laser Scans option and select all E57 files, specify the output folder where the converted files will be saved (which can be used later in other project without repeating the conversion operation);
- add common digital camera images (if any) for the same scene;
- run Align Photos operation as usual.

For the laser scanning data Metashape is using spherical panoramas for the image matching, which are captured by the scanner or the intensity map, if the scanner is not capable of saving spherical panoramas. Then during the dense cloud or mesh generation operation the photogrammetric depth maps are merged with the depth information coming from the laser scanner.

Hello Renato,

Do you have cuda-enable tweak set up via Advanced preferences tab?

Please also provide the output of the following command executed via the Console pane and specify the CUDA driver version installed:
Code: [Select]
Metashape.app.enumGPUDevices()
