Detection and classification of olives in the oil production chain – IRTA
IRTA is a research institute of the Government of Catalonia, which seeks to promote research and technological development in the agrifood sector, as well as to contribute to the modernization, improvement and promotion of competitiveness in various sectors such as agriculture and food, among others.
The Institute approached Basetis in light of their need to speed up the process of classifying olive varieties for one of its projects. Selection is essential to maintain the Protected Designation of Origin of the olive oils produced. There wasn’t any programme to facilitate this work.
Our AI team developed a tool using artificial vision and deep learning capable of recognizing, classifying and segmenting the olives one by one on a conveyor belt.
To achieve this, a database of more than 26,000 images taken on site was built up, which made it possible to create an algorithm with 94% accuracy in classifying the olive variety. A special statistical application allowed the error to tend to 0.
This high degree of accuracy was essential to: secure the designation of origin of the olives and create an intelligent labelling that simplifies the process.
