The application of the optical technique using 3D-printed materials integrated with small digital cameras and micro-controllers/computers offers exciting opportunities to develop a range of devices that can capture, process and analyse the effect on drought on plants in entirely new ways.
The latest Pi, for example, ships with onboard Wi-Fi and Bluetooth, can be connected to a network and the internet, and can be programmed using any modern programming language, which means it can utilise all the best libraries for image processing and scientific analysis. Temperature, humidity and numerous other sensors, add-ons and components, can be incorporated using the general purpose input/output (GPIO) pins that come standard with each board. And that’s all using a computer the size of a credit card. Oh, and then there’s the Pi Zero which can do all this but at half the size…
The Open Source Optical Vulnerability (OpenSourceOV) project has two goals:
The vision of the OpenSourceOV project is an ecosystem of community-developed devices and software that utilise a range of optics, electronics, and image processing techniques to visualise the effect of water stress on plants.
