Strabismus detection system based on vision

Abstract

The invention discloses a strabismus detection system based on vision, and the system comprises an image collection module which is used for collecting a to-be-detected image; a face detection module used for recognizing a face image according to the to-be-detected image; an eye detection module used for recognizing an eye image according to the face image and respectively acquiring contour feature points of two eyes in the eye image; a first calculation module used for respectively calculating pupil center coordinates of the two eyes according to the eye images; and the first judgment module is used for judging the difference value, wherein when the difference value is greater than a preset threshold value, the strabismus of the to-be-detected person exists. By the adoption of the method and device, the pupil inclination rates of the two eyes can be calculated, the difference value of the pupil inclination rates of the two eyes can be calculated, when the difference value is larger than the preset threshold value, strabismus exists in the to-be-detected person, an alarm is given, and strabismus can be found and corrected as soon as possible in time.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a vision-based squint detection system. Background technique [0002] Strabismus refers to the inability of both eyes to fixate on the target at the same time. It belongs to extraocular muscle diseases and can be divided into two categories: common strabismus and paralytic strabismus. Concomitant strabismus is characterized by no movement disturbance of the eyeball and equal degree of strabismus in the first and second positions; paralytic strabismus has limited eye movement and diplopia, which can be congenital or can be caused by trauma, or systemic disease. [0003] The most common group of strabismus is young children. Intermittent strabismus in young children has a certain degree of concealment and does not necessarily appear all the time. It is difficult to be noticed at the initial stage. By the time parents discover the situation, it is often already in a serious situatio...

However, if it is not treated or exercised in time, it may develop into adult strabismus and lose self-regulation ability and turn into constant strabismus when it grows up
