Color detection for drone localization

2017-05-10T16:20:29.140Z

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).

Adaptive visual color tracking

This is a brief demo of visual color detection method that I wrote about two years ago. After an initial calibration phase, where one has to manually specify the color to be detected (in this case: green), the "Auto Detection" mode is switched on. In this mode, the color for which it is being scanned is updated in each iteration based on the colors found. This allows for more robust detection under changing light conditions.
This was made as a Grasshopper plugin playing with System.Drawing.Bitmaps retrieved from a webcam.
