How do you guys make your splats?

[lewibs]

Hi everyone, I'm working on a research project and I have been looking into different methods for guassian splat generation so I can make a data set for object detection.

I've got two questions:

1. How do you guys like to make your guassian splats?
2. Would you be willing to share yours with me at benjaminsl2000@gmail.com?

Do you need splats for object detection, or could a pointcloud generated with e.g. COLMAP suffice?

[seppestaes]

1. I'm using SplatFacto, but don't have a lot of data (yet)
2. How do you plan to annotate the splat/clouds? Cloudcompare? Will you be doing semantic segmentation? Preprocessing with Open3D?

Grtz

@seppestaes Hey! thanks for the response either one would work. From what I can tell the underlying structure between the two is close enough that it could be transferred over.

Ive actually been moving away from using ai to do the heavy lifting and just using something like knn to get the shape of the object, then use the AI to determine the cutoff points.

@lewibs Are you trying two match two pointclouds? If so, you could try Open3D using traditional CV e.g.

• Ensure pointcloud densities correspond
• Matching phases: ColorICP, RANSAC
