A slight tangent but rollerblades is a case of proprietary eponym : Rollerblade is a brand of inline skates (often call skates - plural - for short) that became so famous people started to use it to describe all inline skates, no matter the brand. Just like vaccum cleaner and hoover :)

I once put an Ouster OS1 on a hat and walked around with it. Pic of me here: [1]

Very cool. When was this? If you would repeat it, which LIDAR would you use? Is there anything on a generous hobby budget nowadays?

On cheaper side there's MID360

So cool! I wonder how the Lidar and ARCore poses were cross-calibrated?

Just to avoid this, I would just use a LiDAR equipped iPhone Pro, with industrial grade cross-calibration and still have all the visualization fun.

Wouldn't this be cheaper with a stereo pair of cameras + software reconstruction instead?

That would need WAY more compute.

Also a lot less robust depending on baseline.

You should post this on /r/Photogrammetry on Reddit: https://www.reddit.com/r/photogrammetry/

Very impressive! LiDAR and point clouds seem very promising, but the challenge of denoising point clouds and artifacts keep the skill bar very high/time intensive.

Just install polycam and walk around :)
