Egg Volume and Surface Area Calculationsbased on Machine Vision

Egg volume(V) and surface area(S) are two important geometrical calculations for the poultry industry and in biological studies, as they can be used in research on population and ecological morphology, and to predict chick weight, egg hatchability, shell quality characteristics, and egg interior parameters. With machine vision technology, the objective of the research herein was to develop a much more fast and available method to predict them. Besides, the researcher gave the definition of Volume in Pixels (Vp) and Surface area in Pixels (Sp) for the first time. Finally, new linear models were established. The R value for volume model is 0.88 and surface area is 0.86. The prediction ability of the models are: for volume, the correctness reaches 52% with 1cm statistical errors, 89% with 2cm, for surface, the correctness reaches 49% with 1cm statistical errors , 87% with 2 cm.
