I worked on this project with a friend for a school project as part of the ESA Astro Pi challenge.
The goal was to estimate the speed of the ISS using images of Earth.
We used computer vision to track features between images and measure how far the station moved.
The result was around 7.47 km/s, while the real speed is about 7.66 km/s.
So roughly a 2–3% difference.
One limitation: the original runtime images are lost, so the repo mainly contains test images.
Still thought it was interesting how close you can get using just image analysis.
