Abstract

The invention discloses a strabismus compensation head position detection system and method, and solves the problems that in the prior art, strabismus measurement is not accurate and convenient enough, a measurement scheme is complex, and a judgment effect is affected. The system comprises a head-mounted portion and a target portion, wherein the head-mounted portion comprises a mirror bracket forwearing, two cameras for shooting images of left and right eyes respectively, a gyroscope, three sensors with a distance measurement function and a control system for data processing; before a compensation head position is judged, a sight line is analyzed, whether strabismus occurs is judged according to a sight axis intersection condition, and a reason for head angle deviation is explained; if asight axis intersects with a target, it is indicated that a tester does not suffer from strabismus, and head-slanting object viewing is caused by neck lesions or other reasons and is irrelevant to strabismus; and if the sight axis does not intersect with the target, it is indicated that head angle deviation is caused by strabismus, and obtained deviation data can be used for surgical treatment ofstrabismus. The system and the method have the advantages of simplicity in operation, quick symptom judgment and clear data display.

Description

technical field [0001] The invention relates to the fields of medicine and electronics, in particular to a strabismus compensation head position detection system and method with simple operation and clear data display. Background technique [0002] Strabismus refers to the inability of both eyes to look at the target at the same time. It is an extraocular muscle disease with an incidence rate of about 3% to 5%. It is not uncommon in our daily life. Strabismus not only affects a person's appearance, but also damages the visual function of both eyes, and in severe cases can lead to psychological disorders in patients. Under normal circumstances, the movement of both eyes is coordinated, and both eyes can fixate on the same target, and the target is imaged in the macula of both eyes, transmitted to the visual center of the brain, and superimposed into a complete and stereoscopic single object image. When eye movements are not coordinated for various reasons, one eye can focus ...
