Cracked egg is susceptible to microbes and can contaminate other normal eggs. Eggs with hairline crack should be removed in advance, but hairline crack on eggs is difficult to detect. There are various techniques for detecting micro-cracked eggs, among which the negative pressure method of expanding cracks in eggs has high accuracy. In this study, cracked egg detection system was developed using the negative pressure method. The negative pressure method can be combined with a machine vision device to accurately detect the micro-cracked egg. A vacuum chamber and vacuum pump have been developed to create negative pressure around the egg. Inside the vacuum chamber, rotating and lighting system were installed to candling and rotating the eggs. The image of the egg was acquired with the camera installed at the top of the chamber, and the micro-crack was identified through the developed image processing algorithm. The key to the algorithm is to identify cracks by comparing an egg image at vacuum with an egg image at atmospheric pressure. In order to compensate for the slow processing speed of the negative pressure method, a vacuum chamber was developed so that two units were connected and performed crosswise. It is judged that the vacuum pressure method-based micro-cracked egg detection system can be effectively used in small farms and institutions.
