Sounds like the quality isn't all that great but LD06 sensors look like they're about $20 and someone who works on libraries about this suggested the STL27L which seems to be about $160 and here's an outdoor scan from it: https://sketchfab.com/3d-models/pidar-scan-240901-0647-7997b...

Not sure if the ld06 is a scanner like this or if it's just a line (like you'd use for a cheaper robot vac).
