Color detection for drone localization

This demo shows a Grasshopper plugin developed to detect objects of a certain color. After some manual calibration the search adapts for changing light conditions automatically.
The plugin was initially intended as a drone localisation method for this project: https://vimeo.com/212074407 (sort of a cheap self-made motion capture system) but was never used as such (we decided to go with a tag-based approach later).
