Abstract

The invention is applicable to the technical field of computer detection and provides a pupil detection method and device. The method comprises the following steps of: acquiring pupil iris images of atested object in different luminous flux environments, wherein the pupil iris images comprise a reference image, a dark pupil image and a bright pupil image, and the reference image is used for representing the pupil iris image of the tested object when the luminous flux is preset; respectively calculating a first ratio of the pupil area to the iris area in the reference image, a second ratio ofthe pupil area to the iris area in the dark pupil image and a third ratio of the pupil area to the iris area in the bright pupil image; and determining whether the pupil of the detected object is abnormal or not according to the first ratio, the second ratio, the third ratio and a preset detection model. The method acquires the reference image, the dark pupil image and the bright pupil image of anobject to be detected in environments with different luminous fluxes, calculates the ratios of the pupil area to the iris area in the images, determines whether the pupil of the object to be detectedis abnormal not according to the area ratios, ensures the accuracy and universality of pupil detection, and improves the accuracy of pupil detection.

Description

technical field [0001] The invention belongs to the technical field of computer detection, in particular to a pupil detection method and device. Background technique [0002] As an important information acquisition organ of the human body, the eye not only acquires external light radiation information, but also reflects the pathological changes of multiple tissues and organs of the human body. The pupil expands or contracts after being stimulated by different light sources, but it is the sympathetic and parasympathetic nerves in the oculomotor nerve that control the changes in the pupil. Once these nervous systems are damaged, their ability to control pupillary changes is lost, which is exactly the mechanism by which some diseases can be observed through pupillary changes. Through the observation and measurement of the eyes, not only ophthalmic diseases can be found, but also some systemic diseases can be diagnosed early. [0003] In the prior art, the evaluation of ophtha...
