Sensor for phenolic ripening of grapes
The invention is a system for determining the degree of phenolic ripening of grapes directly in the field from colour digital images acquired through a smartphone. The system is composed of a controlled lighting acquisition compartment, an algorithm on server for image processing and mobile and desktop applications for data management and visualisation.
The device allows to acquire, through a smartphone, colour images of grape samples in a closed compartment, under controlled lighting conditions: the smartphone becomes a real analysis tool.
The images are sent to a server, using a dedicated app. Here the images are stored and processed: an algorithm correlates the colour of the sample with its chemical-physical properties. The results obtained from the processing on the server are sent back to the smartphone and displayed in real time.
An objective, rapid and low-cost measurement system is therefore obtained for various colour-related parameters indicative of phenolic ripening (content of the main anthocyanins, colour index, tonality, etc.).
It is also possible to store, visualise and re-elaborate data from the desktop, using a web interface which allows to create ripening maps and curves
