Assumed the ideal egg image was symmetric about longitudinal diameter, the definition of volume pixel(Vp), surface areas pixel(Sp) and the calculation were proposed. Then, the module between volume (surface area) and Vp (Sp) was established. Experimental results showed that the determination coefficient of volume module and surface area was 0.965 and 0.971, respectively; the test accuracy of egg volume module and surface area reached 92% with ±1 cm3 error and 88% with ±1cm2 error respectively.
