Abstract
A method for non-destructive detection of egg freshness based on centroid measurement. A real-time distance between the centroid position of an egg and the top of a small end of the egg is measured, the ratio of the distance to the length of the egg is defined as a centroid ratio, models are respectively established regarding a centroid ratio change and the number of days the egg has been stored, and regarding the centroid ratio change and the egg freshness, and the number of the days the egg has been stored and the egg freshness are predicted by means of the established models.
