Development of precise tomato yield monitoring to reduce food loss

Computer vision predicts the future in greenhouses before harvesting

Every year a large amount of greenhouse-grown food goes to waste because of non-optimized yield planning, logistics, etc. Tomatoes are one of the most consumed vegetables both in the EU and worldwide, and it is estimated that around 3 mill. tonnes of tomatoes are wasted in the EU annually. This leads to inefficient use of resources and economic loss.​

Greenhouses frequently encounter significant challenges with overproduction and food loss due to mismatches between supply and fluctuating demand. Sudden shifts in market demand can result in surplus produce that exceeds consumption needs, leading to wasted resources. Diseases and mechanical damage lower the quality of some fruit, contributing further to waste. Inefficient harvest planning and timing only worsen these issues, causing unnecessary food loss and financial setbacks.

To tackle these challenges, a precise monitoring system that helps forecast yields accurately and align production with market demands is crucial and could help reduce food loss and waste.

Computer-vision based systems to monitor growing vegetables 

In this project, we are developing an advanced monitoring system to assist farmers in harvest planning and work optimization using computer vision and artificial intelligence.

This system employs multiple cameras to capture images of tomatoes, which are then processed by specialized custom analysis software. This software features machine-learning models designed to identify and count tomato fruits, assess their ripeness, and estimate their weight from the images alone.

The software predicts future tomato yields based on this visual data analysis. Farmers can access these insights via an interactive online dashboard, enabling more informed decision-making and efficient harvest management.

Did you know?

  • In Europe, around 30% of all fruits and vegetables are discarded each year just because of their appearance.
     
  • Food and vegebale waste causes an estimated price increase of €4 per kilo.

Testing and enhancing  

Our objective is to develop a versatile and adaptable solution that can be easily integrated into already established farming practices.

We have reached the stage where the system is functional and all parts are integrated. Our current focus is on optimizing the key components.

To achieve this, we are conducting activities to test and enhance the AI analysis models. This involves rigorous testing and iterative improvements to ensure the models are accurate, efficient, and effective in their analysis and prediction. By refining these models, we aim to enhance the overall performance and reliability of the system, ensuring it meets diverse needs and scenarios.

More efficient resource use and increased competitiveness

The system will mostly benefit the producers by reducing food waste and leading to more efficient resource use and increased competitiveness.

The advantages of efficient yield planning will be felt throughout the supply chain down to the retailers, who also benefit from optimized logistics, and hopefully in the end the consumer who will pay less for their tomatoes.

First results are promising

The testing activities carried out so far have demonstrated that the developed system is functional in real-world environments. Its straightforward design allows for easy integration and compatibility with the hardware already used in commercial greenhouses.

The results of the AI analysis models are promising, and the current system meets the initial criteria set for the solution. Furthermore, there is significant potential for improvement with planned future system enhancements and validations, aiming to increase accuracy and reliability in diverse operational scenarios.
