Gaussian Splatting

[Paulov]

Hello,

Do you plan to introduce hability to generate Gaussian Splatting?

[JMR]

Yeah, sounds and looks interesting, indeed, but to be honest at the moment those things seem like witchcraft to me. and I don't know if in the witches' kitchen shelves there is a jar labeled "tools for an exhaustive control of the metrics".

Hi! You can use script to export camera images and camera alignment and after that use them in gaussian splatting.

Thanks a lot!!

My main issue is to align images, I guess uses Colmap under the hood, an my datasets seem to particularly not owrk nicely in there. I've 3-4 weeks of intense work in other topics but definitelly will try the script!

Hi, any option for Standard version user?
Thanks

Hi, any option for Standard version user?

At the moment I don't know any options for Standard version, because this is a Python script and only Pro version has Python API support.

I thought it uses a point cloud

Yes, Gaussian Splatting uses SfM results (cameras calibration + 3D tie points), so to transfer that information from Metashape project to Colmap format (that is supported as input by Gaussian Splatting) - this script exists. But this scripts uses Metashape Python API that is available only in Metashape Professional.

I dont understand the entire workflow of gaussian splats but it seems that Metashape can already do most of the work needed. Code for the remaining feature already exists and is available, they just need to integrate it.
The main problem I have with other solutions is they are either:
. NVIDIA only
. Web sites with a one solution fits all
. Limit the number of input photos

Hi!
Do you know maybe - is possible way to convert somehow camera + pointcloud/tie data into colmap format without Pro version?
Any advices?
Thanks!

Hi. Sorry, I don't know any alternative methods.
