Abstract: Automated and non-destructive inspection is the key issue in the safety and quality control of fruits and vegetables. The talk introduces a series of work conducted to improve the efficacy of the quality inspection of onions. The optical properties of onion tissues were investigated to develop sensing systems using spectroscopic and imaging methods. A novel multi-sensor-based machine vision system was designed to integrate hyperspectral imaging, RGB-D imaging, and X-ray imaging techniques to evaluate both external and internal quality traits of onions nondestructively. This work lays the groundwork of next generation automated and robotic systems for the quality inspection and grading of fruits and vegetables.
