Frame rejection in yet Another Denmark roundabout video

It’s time for yet another roundabout from Denmark! This time recorded in the city of Randers, using a tethered drone at altitude of 70 meters and processed as a 5-minute demo for COWI. Given that the drone’s range was 80 meters and it appears to be placed some 90 meters away, the result is certainly nice.

Frame rejection capability

Somewhat less nice is that the video has a few erroneous frames (images). So, we added function to fix that – marking frames as rejected for analysis. It does not mesh perfectly with all of the DFS parts yet: You may notice the background blinks (video problem) and that trajectories are smooth (data is cured), but somewhat confusing is that the labels themselves will jump (visualization breaks). Well, that’s a problem of display only, and will get better soon. The data is correct, that mattered as the first goal.

(Note also that since the web video player drops some frames on its own, you have about a 50/50 chance to even notice any single bad frames from the video below – you can try hunting for the one that occurs at about 0:50).

Human convoy simulation tracked with DataFromSky

Researchers from Technical University of Brno recently had an interesting idea: Use a number of students to simulate a convoy with human drivers and measure the dynamics of that situation. To do so, they turned to DataFromSky, their trusted research partner.

It is no coincidence that DFS turned out to be a great tool for such situation – our long-term vision is to be the tool for spatial movement analysis. The students’ positions were marked manually; the rest of needed processing was already part of our software.

Enough rambling, take a look!

A wonderful Denmark crossroad analyzed by DataFromSky

As Denmark has become first country in the world using real-time traffic data all around the country we got the opportunity to analyse one of many busy crossroads in there. For us it is the second time monitoring traffic in Denmark, this time in Rismarksvej. The intersection is four-way and bicycles friendly and controlled by traffic lights.

Length of analyzed video: 11 minutes
Number of objects being tracked: 525 (vehicles and bicycles)
Total distance traveled: 89 044.4 metres
Average speed: 11.104 km per hour

The exact location is:

And we would like to thank to RAMBOLL for providing us a video.
