The many knocked down, shared e-scooters & bikes in Berlin, strengthened by a recent German government decision to further allow their (better regulated) parking in pedestrian areas, but also looked into the wider market need for such a solution - like the added risk of follow-on accidents by fallen-over vehicles on walk- & cycleways, and the optical eyesore they create.
What it does
Detects knocked down scooters & bikes. The AI presumably identifies brands and positions/uprightness of vehicles, based on shapes, colors and saddle position.
How I built it
Azure Custom Vision trained models
Challenges I ran into
Find enough, freely available pictures of scooters/bikes lying around (nextbike was particularly hard).
