Or maybe the resolution is | purposefully poor? | sdan wrote: | Yeah, this definitely doesn't look like lidar data... unless | its really low quality. The buildings show spatial depth, but | the cars and pedestrians are pretty much all in a circle (they | have no depth). | callumprentice wrote: | Interesting - I've seen it touted as LiDAR data but since | it's all a bit unofficial, I guess it could be anything. I'll | see if I can dig up any old articles about it - it's been | there for quite some time. | mthoms wrote: | I don't know much about lidar but.. is it possible Google | have done this intentionally with some sort of algorithm? | After all, pedestrians and vehicles are just "noise" in the | context of mapping/visualising streets. | pantelisk wrote: | It is not proper pointclouds, but it is the data used by Street | view to highlight if you are looking at a wall, or at a street. | It is also used for transitions between one scene to another. | | You can see it is very basic 90deg angle geometry, instead of | actual pointclouds. Still pretty cool! | https://imgur.com/a/EgC0RbN | callumprentice wrote: | FWIW, that's just my own amateurish rendering of the points. | The data itself that the Street View API provides is just an | array of 3d points. | pantelisk wrote: | Oh yeah, I didn't mean to come off as judgemental or | nitpicky. This is fantastic work! And this data can | actually be pretty useful, let's say if somebody wanted to | build a racing game based on street view, using the | boundaries of the street for collisions etc. Too many fun | possibilities! | pj_mukh wrote: | 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 see this depth data IRL. | callumprentice wrote: | Thank you! As far as I know (it's undocumented) the only source | of depth data is very low resolution. The image data (where the | color of each point comes from) is much, much higher - shame | they're not on par with each other. | kevinali3 wrote: | Is there any software (preferably open source) that can be used | to build one's own street views for areas/countries that are not | covered by Google? | callumprentice wrote: | I believe you can publish your own images and have them | available via Google Maps but I've never done it. This might be | a decent starting point: | https://www.google.com/streetview/contributors/ | jefft255 wrote: | Any photogrammetry software will do the trick.
