  • Patent number: 11026571
    Abstract: A method for processing pupil tracking images, comprising the steps of: 1) acquiring eye images multiple times; 2) processing each acquired eye image, and determining whether a pupil can be positioned in the acquired image; and 3) determining that pupil tracking is completed when the pupil can be positioned in consecutive n pieces of eye images. Image processing efficiency is improved by searching a potential bright spot area and carrying out Blob analysis smearing images caused by pupil movement can be eliminated, the pupil edge is accurately positioned by adopting a line drawing method in collaboration with a support vector machine when determining the pupil edge, and finally a weighted least square method is adopted to fit a circle/ellipse (pupil). Therefore, real-time tracking and analysis of the pupil under a complex background are realized, and reliable data are provided for subsequent steps to obtain the refractive parameters of the eye.
