Pedestrian Detection Visualization with Drones

Pedestrian movement data based on drone footage. 20min time snippets taken at 60-65m height.

The tracking pipeline looks like this:

Given 2.7k 25fps video data that works quite well. Cyclists and pedestrians are detected as pedestrians alike and cars only create few false positives. All in all way faster than object detection networks and totally OK for a quick visualization.

Heatmap is based on my python port of D3s hexbin.
