An open-source, low-cost, image-based weed detection device for fallow scenarios
OpenWeedLocator
Welcome to the OpenWeedLocator (OWL) project, an opensource hardware and software green-on-brown weed detector that uses entirely off-the-shelf componentry, very simple green-detection algorithms and entirely 3D printable parts. OWL integrates weed detection on a Raspberry Pi with a relay control board in a custom designed case so you can attach any 12V solenoid, relay, lightbulb or device for low-cost, simple and opensource site-specific weed control. Projects to date have seen OWL mounted on robots and vehicles for spot spraying!
On the weed detection front, a range of algorithms have been provided, each with advantages and disadvantages for your use case. They include ExG (excess green 2g – r – b, developed by Woebbecke et al. 1995), a hue, saturation and value (HSV) threshold and a combined ExG +
