Description
Technical field
This utility model relates to a kind ofly rescues training system based on the binocular stereoscopic visual perception.Native system has the 3D video training short-movie of more than 50 independent development, can be in broadcasts such as 3D TV, 3D computer, 3D projectors, and the patient wears polarized light or the liquid crystal shutter glasses are watched.Every training short-movie duration is about five minutes.The 3D display is the huge carrier of a kind of information capacity, it imports information into brain from 360 degree spaces, vision input, motion and maincenter are produced the intense stimulus impulsion, that tiltedly the amblyopia training method is far away can't be obtained for tradition, for oblique amblyopia Comprehensive Treatment provides new means, has novelty.
Background technology
The relief process of setting up of people's vision is: eyes are watched object simultaneously attentively, the eyes sight line intersects at a bit, be point of fixation, the luminous point that reflects back on the retina from point of fixation is corresponding, and this two signal of naming a person for a particular job changes the picture of the synthetic complete object of the brain visual center over to.Not only seen this point clearly, and this point and on every side the distance between object, the degree of depth, convex-concave etc. can both distinguish out that the picture that becomes like this is exactly three-dimensional picture, this vision also is stereoscopic vision.
Stereoscopic vision clinically more adopts two-dimentional sighting target to measure, and of a great variety, some belongs to qualitative examination, and some belongs to quantitative check, the sensitivity that can measure stereoscopic vision, take second radian as unit, the number of degrees are less, sensitivity is higher.Check with the larger picture of parallax first, be transitioned into gradually the less picture of parallax, can detect real Stereoacuity like this.Two stereopsis pictures are put into insert box, and both arms are put near merging point, in order to form stereoscopic vision.
Random point stereopsis test method has been used Random-dot Stereograms RDS to technology, and the only key element of detection is visual disparity, does not have monocular cue.But the person under inspection needs to wear auxiliary separating from glasses (mycyscope or polarised light glasses) when checking, to realize the separation of eyes image.This method is comparatively simple, and separating effect is also ideal, but has brought inconvenience for some special populations (such as child and Er disease of the nose patient etc.), and many people wear the probability that has increased cross infection with a pair of glasses simultaneously.In addition, auxiliary separating has also changed definition, brightness and the color of image when glasses separate the eyes image, can not truly reflect the stereoscopic vision state of people under naturalness.
