Abstract

In the present study, we developed a device for the non-destructive detection of abnormal eggs (mainly eggs with cracked shells, eggs with leaking cracks, unclean eggs, and eggs with blood spots). This device incorporates color and monochrome CCD cameras. Determination of eggs with a cracked shell is done by processing the transmission image of the egg acquired using the color CCD camera. To determine eggs with blood spots, eggs are irradiated with light of the wavelength band that absorbs blood and the permeating light is captured with the monochrome CCD camera, after which the image data are processed. The results suggest that all types of abnormal eggs can be detected with a high precision of 95.0%~98.5%.
