Variable-focus human eyeball imitation structure driven by linear performer

Abstract

The invention discloses a variable-focus human eyeball imitation structure driven by a linear performer. One end of a support casing of an imitation human eyeball is fixed in an eyeball body; a central line passes through the ball center of the eyeball body; a micro image sensor and an artificial lens are arranged on the support casing respectively; a cylindrical linear motion performer is sleeved on the outer side of the support casing; one end of the performer is fixed on an eyeball end cover through a positioning pin while the other end is provided with a planar non-light tight lens which is in contact with the artificial lens; and the linear displacement performer drives the non-light tight lens to change the shape of the artificial lens and realize an automatic focusing function. Thestructure has the advantages of small size processing, compact structure, high integration degree, and vision adjusting function, and an ideal structural scheme for an artificial eye and an intelligent vision system is provided, the application field of the simulation human eyeball is expanded and the structure is suitable for various artificial eyes, humanoid robots and intelligent monitoring and stable tracking systems.

Description

technical field [0001] The invention relates to an imitation human eyeball structure, in particular to a linear actuator driven zoomable human eyeball imitation structure. Background technique [0002] Humanoid eyeballs with visual functions have the advantages of small size, light weight, flexible movement, high degree of integration, and beautiful appearance. They are widely used in interdisciplinary fields such as vision restoration, humanoid robots, intelligent image processing, and ophthalmology research. [0003] The restoration of visual function of the blind, the installation of artificial eyes for patients with eye diseases, the research on human eye movement models in ophthalmology, the vision system of humanoid robots, the detection of pipelines and small spaces, and intelligent tracking are all of great scientific significance. Small, flexible, highly integrated, humanoid eyeball with visual function. [0004] At present, the main way to solve visual impairment ...

AI Technical Summary

Problems solved by technology

[0004] At present, the main method to solve visual impairment is to replace the diseased organs with artificial prosthesis, including: lens prosthesis, retinal prosthesis, visual cortex prosthesis and optic nerve prosthesis, which can solve the problem of partial visual function recovery of visually impaired patients, but It is still impossible to realize the more comprehensive functions of the human eyeball. The ciliary muscle of the human eye pulls the lens to deform and adjust the focal length, so that the retina of the human eye can form clear images of objects with different depths of field; the artificial eye system that realizes visual functions at this stage is generally Using the method that the patient wears glasses with a camera is neither beautiful nor convenient

The traditional robot vision system has a large structural size and low flexibility, and it is difficult to apply it in an environment with relatively strict requirements such as narrow space and flexible movement.
