Fascinating and cool visualisation of Street View depth data
From 3 comments
This is very cool! I'm thinking the depth data that is captured is of higher resolution. Is that true? Was this limited by the API? Or a limitation of the browser? Super cool to…
pj_mukh on HNThat's a possibility. Are you rotating your squares in just the xy plane, or also along the "pitch"? I find your project fascinating, thank you for sharing it!
saeranv on HNWorks here on Arch Linux, Firefox 76.0.1 (yeah, I need to upgrade).

Unclear whether the data is really LiDAR
From 2 comments
That's doesn't properly look like lidar data to me; at least it wouldn't be lidar that is mounted right on the street view car. Maybe they use aerial lidar somehow? Or maybe the…

Why point density falls off toward view edges

saeranv on HNOkay, so it has nothing to do with the orientation of the point planes. Having thought about it some more, I think this is a consequence of the reduction of surface area hit by…

How Google builds clean polygons from point data
From 1 comment
Looking at this makes me wonder how Google combines the point data to generate clean polygons. I.e when I hover my mouse over a wall in Street View, it identifies correctly the…

OpenStreetCam and Mapillary for user-built street imagery
From 2 comments
I've seen a project by OpenStreetMap to upload dashcam images, and a quick search gave me this: https://openstreetcam.org
netsharc on HNThe software is not open-source but both Mapillary and OpenStreetCam have very permissive licenses. I contribute to and use both services to improve OpenStreetMap. Mapillary:…
