Road section UAV-scanned in Finnish Lapland

Post by hakkilhe » Fri Sep 07, 2018 8:00 am

Hi!

Last year we participated in Aurora Arctic Drone Challenge at Hetta, Finnish Lapland: https://ultrahack.org/auroraarcticdrone
It was about to "to create future services by using drones in road maintenance operations" especially in winter conditions. How to get the information about sidelines, centre lines, zebra crossings and frozen culverts and ditches/height of snow banks etc.

Everyone had to scan or photo the same 3.1km long section of the highway 93 and then get the needed information out of the data.

I made a short video out of our data, scanned with Riegl RiCOPTER / VUX-1UAV system. It's just a simple video made from the point cloud with ReCap (no proper editing) and Youtube seem to have messed up with the video quality, but anyways, here it is.

The colorization of the point cloud isn't so good. There was still a lot of snow and I did the colorization with standard parameters so the smaller trees also got white color (especially birches and other deciduous trees because at that time of year they didn't have any leaves).

very interesting. to find the iced area you filtered by deviation in RiScan Pro?
which format file did you use to import the point cloud’s from RiScan to Recap for your video?

thanks and .... bravo!

Nice work! Is the resultant data for all entries being published for public consumption?

I used RiProcess / RiPrecision for processing and matching the data (like we always do with UAV and mobile data), then Terrasolid TerraScan for further classifications and measurements for the challenge. Actually didn't try to filter iced areas by deviation (was not needed fot the challenge) but good idea, that would probably work with the right parameters!

I imported files to ReCap in LAS1.2 format, worked fine.

Good question, I don't really know. But the challenge was a part of bigger project, E8 - Aurora, the Arctic intelligent transport test ecosystem
