Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Area of Science:

  • Agricultural Engineering
  • Computer Vision
  • Artificial Intelligence

Background:

  • Manual sorting of defective citrus fruits is inefficient, costly, and inaccurate.
  • There is a need for automated, high-precision sorting solutions in the citrus industry.

Purpose of the Study:

  • To develop and implement a deep learning-based vision system for on-line, automated sorting of defective citrus fruits.
  • To enhance the efficiency, accuracy, and cost-effectiveness of citrus fruit processing.

Main Methods:

  • A convolutional neural network (CNN) was used for detecting and classifying defective citrus fruits.
  • The SORT (Simple Online and Realtime Tracking) algorithm tracked fruit classifications.
  • A linear Kalman filter predicted fruit trajectories for robotic arm guidance.

Main Results:

  • The vision system achieved a high detection precision of 93.6%.
  • The integrated system demonstrated effective on-line sorting capabilities.
  • The Kalman filter enabled accurate path prediction for robotic removal.

Conclusions:

  • The developed deep learning vision system offers a practical, low-cost, and highly efficient solution for on-line citrus sorting.
  • This technology significantly improves upon traditional manual sorting methods.
  • The system paves the way for automated quality control in fruit processing.
