Summary:The invention discloses an animal iris positioning method and system. The positioning method comprises the following steps: acquiring an iris image of an animal; performing binarization processing onthe iris image; tracking the iris image subjected to binarization processing by adopting a contour tracking algorithm, and determining the contour of each closed region of the iris image subjected tobinarization processing; extracting characteristic parameters of the contour of each closed area; taking a closed region of the characteristic parameter in a pupil parameter threshold range as a contour region of the pupil; amplifying the contour area of the pupil according to the average proportion of the pupil to the iris of the animal to obtain the outer edge contour area of the iris of the animal. According to the invention, after binarization processing is carried out on the iris image, the contour area of the pupil with high identification degree is firstly acquired, and then amplification is carried out to acqui
