Can you save the lidar mapping data off the unit?

  This custom integration provides a way to present a live view of a map for Xiaomi (Roborock/Viomi/Roidmi/Dreame) vacuums without a need for rooting.

There's a Xiaomi Cloud Map Extractor integration for Home Assistant, not a mod as much as a spoof maybe: that gives you the maps as you see it them the Roborock or Mi apps, and are stored on the vacuum,. I think that's it-- storing the map as a bitmap is efficient storage- and compute-wise. Screen grabbing from the app would give the same thing, I wonder what its real resolution is. Also I would guess the map is used mostly as a guide for overall positioning, and that the real LIDAR work is done while running to solve its position on the map as a 3DOF problem, and that data just churns.
