This is wonderful.

What I have been mulling about of late - is LIDAR drones and LIDAR accessories to bicycles - it would be great to have a lidar mapper on my MTB

Here is my MTB https://imgur.com/gallery/aca4tSU

I want to mount lidar to this to map trails it rides...

What recommendations may you have to accomplish this cleanly and cheaply given your release?

In terms of advice, I would for sure start by adding GPS logging into the app. The app logs the ARKit odometry information, which could be a good starting point, but don't know how well that would perform with all that vibration.

It would for sure be a fun experiment, but I think given the extreme conditions, it might be easier to build a custom SLAM sensor rig with a high-quality IMU and several synchronized cameras.

That sounds awesome. I do some mountain biking myself and have sometimes thought that it would be cool if you could replay your rides in 3D through a sparse SLAM point cloud. Of course it would very hard to run SLAM onboard an MTB as there is so much vibration and changes in lighting.

If you could have an accelerometer read, like from the phone running the app, mitigate vibration offsets in measurements that would be cool. This is all beyond my capabilities, but I'd pay some HNer is they can build a LIDAR scanner I can mount to bike...
