<p>The invention relates to an egg candling method for determining the state of eggs between the third and seventeenth days, and in particular for determining the living or dead state of said egg. According to the invention, the egg is illuminated with a green or blue light for visually showing on the shell a shadow of the blood network supplying the embryo if the network is present in the egg. At least one image of the egg is acquired and processed in order to determine the vitality level of the egg based on the presence of said blood network or the lack thereof, and based on the size of the veins of said blood network if present. The method can also be used for characterising the presence or absence of an air space at the upper portion of the egg and thus defining the inverted or uninverted position of the egg. The method can finally be used for detecting lesions on the shell, and particularly cracked shells.</p> |
