The retina cell is nearly more than 100,000,000 in each eyeball of people, each cell surface diameter is about 2-6 μ m, they are distributed on the concave ball shape retina equably, set up people's eyeball perfect optics regulating system model respectively, retina cell's induction model in the eyeball to the visible light of different colours varying strength, the desirable mathematical distribution model of retina cell's set in the eyeball, the electrophysiology information addressing conduction model of visual response cell mass, cerebral cortex visual zone left and right sides visual image prime number is learned the logical operation synthetic model, brain cooperates other sensory perception information and produces the model of final sensed image in the past with reference to vision historical trace information and learning experience.With various ideal models the binocular vision process is described below, the perfect optics regulating system comprises folding, may command light-inletting quantity iris, the imaging crystal of eyelid and regulates muscle accordingly and the adjusting muscle and the refreshing smart conduction path that move up and down and focus in refreshing smart conduction path, binocular vision zone, and their common coordinative role makes on people's the retina of both eyes and clearly manifests the extraneous scenery optical imaging that human brain is thought perception; On intraocular retina cell's shape and function, can be divided into cones and rod cells, because of respectively having superiority to the power of light and color reaction, they determine their quantity and the difference of distribution, is that benchmark numbers in order with each cell with the cell position on the eyeball visual axis, and the retina cell has L in the left eye ball
1... L
N(N=1.07 hundred million, and is variant specific to everyone), the retina cell has R in the right eye ball
1... R
NEach retina cell has corresponding god to be proficient in the road to link to each other with the visual centre of brain, the retina cell is divided into variable two parts by the zone in the left eye ball, a part is variable haplopia district, a part is variable diplopia field, the retina cell also is divided into variable two parts by the zone in the right eye ball, a part is variable haplopia district, a part is variable diplopia field, retina cell's diplopia area size is along with the angle of binocular visual axis changes and respective change in the ball, the interior retina cell's haplopia area size of ball this moment changes and correspondingly does with the diplopia area size variation of complementation along with the angle of binocular visual axis, about 150 degree of left eye horizontal direction angular field of view, about 150 degree of right eye horizontal direction angular field of view, about 140 degree of the vertical direction angular field of view of right and left eyes, about 180 degree of horizontal direction angular field of view after the angular field of view logical OR computing of right and left eyes, about 140 degree of vertical apparent direction angular region; About 120 degree of horizontal direction angular field of view behind the angular field of view logic and operation of right and left eyes, about 140 degree of vertical direction angular field of view, focus on the corresponding change of angle of the variation adjusting optical axis of three-dimensional scenery distance along with eyes, horizontal direction visual angle size is to there being faint variation behind the angular field of view logic and operation of right and left eyes, the size of retina cell's diplopia field of right and left eyes is corresponding simultaneously changes synchronously, though retina cell's diplopia zone of right and left eyes the imaging content identical, but the viewpoint of its observation is at a distance of about 65 millimeters and make the local detail of imaging that certain difference be arranged, the imaging of retina of left eye cell diplopia zone is the take back image of face of observing scene, the imaging of retina of right eye cell diplopia zone is the take over image of face of observing scene, and the degree of their each local overlapping dislocation focuses on the corresponding synchronous change of variation of three-dimensional scenery distance simultaneously along with eyes.When eyes are watched scenery outside 500 meters, binocular visual axis is substantially parallel, arbitrary air coordinates is put the straight line at pupil of left eye center and the angle Φ L between the left eye optical axis and this point to the straight line at pupil of right eye center and the angle Φ R basically identical between the right eye optical axis on 500 meters outer scenery, make the imaging content in 500 meters outer scenery retina cell's diplopia zone of retina cell's set in the right and left eyes eyeball identical, size and retina cell's sizableness of its dislocation though local detail has small dislocation, the electrophysiology information addressing conduction model of visual response cell mass that causes each retina cell's diplopia zone of right and left eyes adopts symmetrical contraposition addressing mode to learn the diplopia zone corresponding diagram picture signals that the logical operation synthetic model transmits few of difference to the left and right sides of cerebral cortex visual zone visual image prime number, learn haplopia range image signal that the logical operation synthetic model transmits with the simple independent addressing conduction of electrophysiology information of the visual response cell mass in each retina cell's haplopia zone of right and left eyes to cerebral cortex visual zone left and right sides visual image prime number and be merged into scenery image outside in the eyes angular field of view 500 meters, thisly lack the final processing that the relief image of partial 3 d (producing with the bioelectricity form) cooperates other sensory perception information again and produces sensed image with reference to vision historical trace information and learning experience in the past (with the bioelectricity form in brain) in brain near two-dimensional characteristics, also can produce certain stereo perception to some scenery by the comprehensive comparison of integral body or local message, but this stereo perception varies with each individual and results from the final stage of binocular vision process, and this stereo perception degree brachytely degree is slow.When eyes are watched the scenery at 10 meters, the binocular visual axis ψ that forms an angle, arbitrary air coordinates point D on 10 meters the scenery
X, Y, ZArrive the straight line at pupil of right eye center and the angle χ R between the right eye optical axis because of D to the straight line at pupil of left eye center and the angle χ L between the left eye optical axis and this
X, Y, ZX, Y, each parameter change of Z and marked change, though the imaging content in the scenery at 10 meters retina cell's diplopia zone of retina cell's set in the right and left eyes eyeball is identical, to the arbitrary air coordinates point D of the scenery at 10 meters
X, Y, ZThe arbitrary air coordinates point D of respective differences similarities and differences scenery of the coordinate position of the imaging in retina cell's diplopia zone of retina cell's set in the right and left eyes eyeball
X, Y, ZWith eyes cooperate angle parameter χ L, χ R has direct relation, there were significant differences to make the coordinate of 10 meters the scenery corresponding pixel of the imaging in retina cell's diplopia zone of retina cell's set in the right and left eyes eyeball, the electrophysiology information addressing conduction model contraposition indexed addressing of visual response cell mass that causes each retina cell's diplopia zone of right and left eyes is learned the logical operation synthetic model to cerebral cortex visual zone left and right sides visual image prime number and is transmitted the diplopia zone contraposition picture intelligence with local coordinate difference, cerebral cortex visual zone left and right sides visual image prime number is learned the logical operation synthetic model and is received after these diplopia contraposition information every pair of pixel according to it on a left side, the numbering of the imaging on the retina of right eye or respective coordinates are carried out fast accurate mathematics trigonometric function operation, big within 15 milliseconds the tens million of electricity physiological signals to each retina cell's diplopia zone of right and left eyes to the paired pixel on the retina cell blur scanning calculating, draw the stereoscopic three-dimensional image of 10 meters scenery visual angle diplopia field, learning the scenery combination stereogram that haplopia range image signal that the logical operation synthetic model transmits is merged into 10 meters in the eyes angular field of view with the simple independent addressing conduction of electrophysiology information of the visual response cell mass in each retina cell's haplopia zone of right and left eyes to cerebral cortex visual zone left and right sides visual image prime number resembles, the formation time of scenery combination stereogram elephant in this eyes angular field of view is approximately 16 milliseconds (receiving the picture information that 60 frames change by the multipotency of human eye per second calculates), in brain, the producing in real time fast and cooperate other sensory perception information and the visual electrophysiology picture information that produces is done last processing of scenery combination stereogram elephant in this eyes angular field of view with reference to vision historical trace information and learning experience in the past with the bioelectricity form, scenery combination stereogram in this eyes angular field of view resembled in brain exist with the bioelectricity form, approximately through disappearing after 40 milliseconds short time, carry out about 40 milliseconds short time memory (retentivity time of eye that promptly it has often been said), can produce stereo perception by the comprehensive comparison of integral body or local message to the local image in the haplopia district of the scenery combination stereogram elephant in the eyes angular field of view, this stereo perception is people's a vision natural reaction.
When people's eyes are watched plane film and TV, plane dynamic picture imaging in normal person's double eyeball on the retina is identical, three-dimensional scenery beyond the stereoeffect that it is faint and normal person's eyes are watched 500 meters is similar, have only by to the time of concrete dynamic image, in the spatial dimension various contrast perception and produce faint stereoeffect, this faint stereoeffect is different because of people's emotion, different because of the scope of one's knowledge of people, different because of people's practice accumulation, because of specifically the dynamic image content is different.
The people is to evolve and come through eliminating according to qualifications of the biology in 10000000 year as five-star animal, it also is state-of-the-art that the integrated performance index of its vision system is compared with rudimentary animal vision system, though the multipotency of human eye per second receives the picture information that 60 frames change, and can receive the picture information that 300 frames change as the compound eye per second of fly, but real-time synchronous driving of hundreds of millions of its three-dimensional contraposition electrophysiology information of the visual sense photo-cell of human eye and calculating are quite complicated, to such an extent as to every millisecond of calculated amount number is with human three-dimensional sensitization identification processing hardware and the software systems that can not do similar performance and speed of TFlops; And the visual impression photo-cell of fly's eye is thousands of, and its three-dimensional contraposition transmits in real time with the speed of calculating and the ability mankind adopts current quick wafer and sensitization identification processing system just may simulate; Visual sense photo-cell sum also is less than human eye though the hawkeye retina cell is intensive to every square millimeter 1,000,000 quantity and can clearly differentiate toy outside the 1KM, and its eyeball is little; The night vision animal is in one aspect outstanding of ability of some characteristic of its optical system and visual sense photo-cell induction low-light and reduce other function or the comprehensive function of its vision system; Some complex process and the power that utilize human binocular stereoscopic to look are done simple declaration by following experiment to the stereo perception variation of some plan view image.
It is a quite complicated process that people's binocular stereoscopic is looked fusion, utilizing timesharing to replace three-dimensional display cooperates special eyeglasses that the normal person is done several stereopsis test experience, special eyeglasses only allows timesharing to replace odd-numbered frame image imaging on the retina in the left eye ball that three-dimensional display shows, (corresponding region on the interior retina of right eye ball this moment is complete black imaging), special eyeglasses only allows timesharing to replace even frame image imaging on the retina in the right eye ball that three-dimensional display shows, (corresponding region on the interior retina of left eye ball this moment is complete black imaging), when replacing three-dimensional display, timesharing shows certain odd-numbered frame image and even frame image content fully not simultaneously, such as the odd-numbered frame image is the colored tiger of a width of cloth and the even frame image be a cage of topped tiger size, closes whole stereopsis fusion in cage because of the corresponding pixel of imaging on the retina in the double eyeball has very big difference to produce tiger at last through each process of binocular vision; When replacing three-dimensional display, timesharing shows that certain odd-numbered frame image and even frame image content major part are corresponding when identical, such as the odd-numbered frame image be the width of cloth head of taking back the part of having a beginning but no end colored tiger image and the even frame image head that to be a width of cloth take over has the part of tail colored tiger image without a head towards a left side towards a left side, in the double eyeball on the retina imaging identification merge through the contraposition of the corresponding pixel in part and the last stereopsis that produces a complete colored tiger image that has a beginning and an end of each process of binocular vision; When timesharing replace three-dimensional display show certain odd-numbered frame image and even frame image content be complete mutually the photochrome of certain depth of field is arranged the time, because of the corresponding pixel of imaging on the retina in the double eyeball in certain period do not have difference, its visual effect feels basic identical with the corresponding photo that flat-panel screens shows through the eyes direct viewing; When timesharing replaces three-dimensional display when showing that certain odd-numbered frame image and even frame image content are the identical photochrome that certain depth of field arranged, correspondence is odd-numbered frame image red partially (be photochrome red component information strengthen) even frame image blue or green partially (is photochrome is green, blue component information strengthen), because of the corresponding pixel of imaging on the retina in the double eyeball has minimum difference through the last stereopsis fusion that produces than weak degrees of each process of binocular vision; When timesharing replaces three-dimensional display when showing that the odd-numbered frame position of image that misplaces about certain odd-numbered frame image and even frame image content are the identical horizontal direction that certain depth of field is arranged is taken back the right color green grass or young crops of red partially (being that photochrome red component information strengthens) the even frame image off normal offset of color (be photochrome is green, blue component information strengthen) photochrome, because of the corresponding pixel of imaging on the retina in the double eyeball has minimum difference and through the contraposition of the corresponding pixel in part and the last stereopsis fusion that produces to a certain degree of each process of binocular vision; When replacing three-dimensional display, timesharing shows to take back the odd-numbered frame position of image that misplaces about certain odd-numbered frame image and even frame image content are the identical horizontal direction that certain depth of field is arranged the offset of red component image (promptly having only photochrome red component monochrome information) even frame image off normal is right greenly (promptly have only photochrome green with the blue component image, during blue component information) photochrome, because of the corresponding pixel of imaging on the retina in the double eyeball has very big difference and produces stronger stereopsis and merge through each process of the contraposition of the corresponding pixel in part and binocular vision is last, at this moment, green on red pixel on the retina of left eye on a certain visual cell and the retina of right eye on the contraposition visual cell, the left side of blue picture element in the human brain stereotactic procedures, the logical OR computing of right contraposition pixel draw near with photochrome in corresponding color pixel, the whole and local color of the image that the stronger stereopsis of generation is merged is near photochrome;
