Induction imaging system for watching large-format repeated pattern stereograph with naked eyes

Technical Field

The utility model belongs to stereoscopic vision imaging technique especially watches big breadth repeated arrangement pattern type three-dimensional stereograph for the bore hole and provides the induced imaging system who forms the stereoscopic vision.

Background

In the nineties of the last century, a 'repeated-row three-dimensional stereograph' technology which can enable naked-eye viewers to generate stereoscopic vision is introduced into China from abroad. In fact, this kind of picture has been called simply "three-dimensional stereograph" (or "stereograph") from now on, but now the word "three-dimensional stereograph" is greatly generalized, it also refers to many other kinds of pictures, and for the sake of no confusion we have added a specific term here and called "repetitive pattern three-dimensional stereograph" and simply called "repetitive pattern stereograph". In the first few years after the introduction of repetitive pattern stereographs into China, a large number of pictures designed and drawn by Chinese people are published in various magazines in the forms of inserts, back covers and the like, and are also collected and published in books, such as three-dimensional stereograph collection published by Chinese building material industry publisher in 1995 (Hunting edition), and a plurality of works are published on the internet successively, such as a special websitehttp://www.liuhs.comPublished Liu hong Shi three-dimensional stereograph works. At that time, such pictures are widely known, and it is tried to see a stereoscopic image from the picture. Unfortunately, only a few viewers are able to produce stereoscopic vision, while most people are dismissed because they cannot find the sensation for a long time. In addition, in view of the difficulty in forming stereoscopic vision, design renderers all make the pictures very small, generally as large as journal pages, and are difficult to have practical application in the aspects of billboards, murals and the like. For these reasons, such pictures are now quite cold after a burst has been taken.

It would be useful if such a repetitive pattern stereogram were able to be made stereoscopic relatively easily by a viewer with the naked eye, especially if a large format picture were able to be viewed by many people as a stereogram. The patent proposes a technical scheme for solving the problem. As background knowledge of the technical solution, it is necessary to briefly explain what kind of picture is a repetitive pattern stereograph and what principle of forming stereoscopic vision by the picture.

First, a repetitive pattern stereogram is modeled: the picture is divided into a plurality of narrow lines from top to bottom, each line is further dispersed into a plurality of 'patches' arranged from left to right, the patches with the same pattern in the patches form a 'patch string', namely, one patch string is formed by arranging a plurality of patches with the same pattern at equal or unequal intervals, one line is formed by a plurality of patch strings, and the patterns of the patches in each two patch strings are different. For a cluster of spots arranged at equal intervals, a segment containing a spot and having a length equal to the interval is called a "primitive", and the cluster is repeatedly arranged by translating a primitive by an interval every time, and the size of the interval is called a "spot interval parameter" of the cluster.

Simplifying the repeated pattern stereograph into a 'three-pattern-spot model': the picture is provided with only one pattern spot string, which is formed by arranging three pattern spots serving as light spots from left to right at equal intervals, and the pattern spot interval parameter is smaller than the interpupillary distance of two eyes, such as the P plane in figures 1 and 2A、B、CShown by three dots. Left and right eyes of the observerE _LAndE _Rlooking simultaneously at the picture in front of the picture P, the following two situations may occur.

[1] If two eyes only watch the 'light spot string' formed by three light spots on the picture, as shown in fig. 1, two light rays respectively emitted to the left eye and the right eye by each light spot form a 'light spot figure' in the sense after being processed by the visual nervous system, and the position of the light spot figure is coincident with the original light spot, namely, the 'light spot figure string' (or 'light spot string figure') formed by the three light spot figures in the sense is coincident with the light spot string on the picture.

[2] If both eyes are looking somewhere behind the picture, as shown in fig. 2, the following may occur in this case: light spotAAnd spots separated by a spaceB，Two light spots respectively emit to the leftTwo rays of the right eyeAE _LAndBE _Rwhose reverse extension lines intersect atA _LAndB _Ra point of common representationA _L-B _RTwo light raysAE _LAndBE _Rlike in a pointA _L-B _RTwo light rays emitted to the left and right eyes from one light spot, so that the two light raysAE _LAndBE _Rafter the fusion processing of the optic nervous system, a light spot shape image in the sense can be formed, and the position of the light spot shape image is positioned at a pointA _L-B _R(ii) a For the same reason, it is also possible to create a point in one of the sensesB _L-C _RThe light spot shape of (2); two spots in the sense ofA _L-B _RAndB _L-C _Rthe formed light spot shape image string is positioned behind the picture and keeps a certain distance with the picture, the distance is called as the deep diameter of the light spot shape image string, and the visual nerve generates the deep diameter sense, namely generates the stereoscopic vision; this manner of creating stereo vision from a cluster of spots is referred to as "translational-fold stereo imaging" and is "translational-fold stereo imaging by one space".

The distance between the light spot image string behind the picture and the picture is formed as described in the above [ 2 ]xCan be calculated according to the geometry:x = (d÷(e -d) )×shere, thedThe distance between the adjacent image spots is the same,ethe interpupillary distance between two eyes is about 60-65 mm,sdistance from eye to picture; this formula shows: when the distance from the eyes to the picturesAt fixed, at the interval of the pattern spotsdLess than the interpupillary distanceeOn the premise of (A) under the condition of (B),dthe larger, thexThe larger the depth, namely the larger the depth diameter of the light spot shape image string; if the pattern spot intervaldEqual to or greater than the interpupillary distanceeIf so, a positive number cannot be calculatedxThis means that the light spot image string behind the picture cannot be seen; however, in reality this formula is only indIs relatively small andscalculated at a not too great timexExactly to the actual situation, due to the stereoscopic visionOther mechanisms of formation and also of the optic nerve play a role, so that the reality is: when in used < eTo approacheThe depth of the time-light spot image string is smaller than that calculated according to a formulaxWhen is coming into contact withd > eWhen it is needed todThe light spot shape image string at a far position can still be seen without being too large; when the distance from the eyes to the picturesWhen large, the pattern spot intervaldEven reaching the interpupillary distanceeStill, a deep radial impression is possible by a factor of 2. In any case, the spot interval is always the spot shape image string behind the picturedThe larger the spot form string is, the further back from the picture.

As described above, if both eyes watch the back of the three-spot picture, the two-spot image with a definite depth diameter may be seenA _L-B _RAndB _L-C _R(ii) a While also seeing a spot image on each of the left and right sides of the spot image stringA _RAndC _Lsee fig. 2, but the depth of the two spots is not clear in perception, becauseA _RThe resulting image is viewed by the right eye only,C _Lthe shape image formed by the left eye is only watched, but not formed by the fusion of the two eyes; it is only possible to shape the two spots as determined by the depth-path, unless there is support from other information from the picture.

From the above [ 1 ] and [ 2 ], when the same repetitive pattern stereograph is viewed with naked eyes, both a planar image and a deep-diameter stereograph can be viewed, and the key to viewing the stereograph is that the viewer adjusts the state of the optic nerve to watch the back of the stereograph.

If a repetitive pattern stereogram is only three equally spaced spots, it is difficult to see the pattern with deep diameter described in [ 2 ] above, and the repetitive pattern stereogram is generally made easy to make stereoscopic vision by: making the pattern spot string contain many pattern spots, i.e. repeatedly arranging a picture element for many times; (b) placing a plurality of same-length image spot strings with same image spot interval parameters but different image spots in the same line segment with the same length to increase the image spot density, wherein a section of the image with the size equal to the interval parameters comprises a plurality of image spots with different patterns, and becomes a pixel containing a plurality of image spots, and even the image spots in the pixel are connected into a continuous image; (c) placing the image spot cluster which is not easy to generate the deep radial sense near the image spot cluster which is easy to generate the deep radial sense, when the latter generates the deep radial sense, the former can also easily generate the deep radial sense by comparing with the latter, and the effect is called 'comparison-expansion effect for forming the stereoscopic vision'; the pattern spot strings that originally do not easily generate a deep radial sense are, for example, the following: short clusters of spots containing fewer spots, clusters of spots arranged at unequal intervals, each spot in the cluster not having the same but similar pattern.

Fig. 3 is a "repetitive pattern stereogram model" generalized from a common repetitive pattern stereogram, and how a three-dimensional scene will be seen by it is explained as follows: in line 3.1, there are two clusters of spots, the spots are "O-shaped" and "I-shaped" patterns, and the spacing parameters of the spots are alld ₁The drawing line 3.2 is identical to the drawing line 3.1; the parameter of the spot interval of the spot string in line 3.3 isd ₂，d ₂ < d ₁(ii) a In vision, the image of the cluster with deep diameter produced by lines 3.1 and 3.2 appears as a back curtain of a stage, while line 3.3 appears as the front edge of the stage; line 3.4 and the lines in the vicinity, the parameter of the spot interval of the spot string from top to bottom being defined byd ₁Is gradually reduced tod ₂What appears is a stage extending forward from the lower edge of the rear curtain; the picture line 3.5 and the upper and lower picture lines have the same structure and can be divided into a left part, a middle part and a right part, and the middle part is an upper and a lower three-pattern-spot interval parameterd ₃The cluster of pattern spots of (a) is,d ₃ < d ₁and is andd ₃ > d ₂the pattern spots on the left part are not arranged at equal intervals, but from left to rightd ₁Is reduced tod ₃The interval between adjacent spots of the right part is from right to leftd ₁Is reduced tod ₃Thus, the three lines show a middleThe curved object which is convex forwards and the two sides of which are close to the back curtain backwards is positioned on the stage. The repeated arrangement of the lines 3.1 and 3.2 has strict periodicity, while the repeated arrangement of the line 3.5 sandwiched between them has no strict periodicity, so that the former easily generates the deep radial sense and the latter hardly generates the deep radial sense, but by means of the comparison-expansion effect of the stereoscopic vision, when the former generates the deep radial sense, the latter close to the former is driven to generate the deep radial sense; for another example, looking down from the drawing line 3.2 through the drawing line 3.4 to the drawing line 3.3, where there are through lines from top to bottom connecting the internally associated patches in each line, the "compare-expand effect" works more easily, and as long as one drawing line forms the deep radial sense, it will drive each drawing line to form the deep radial sense. A large number of repetitive-pattern stereograms have been published, and the basic way to represent a stereogram is shown in the model shown in fig. 3.

How to view a repetitive-pattern stereogram to enable stereoscopic vision has been reported in various ways, for example, as disclosed in the article "three-dimensional stereogram" of "Sao Gou encyclopedia", seehttps://baike.sogou.com/ v411113.htmzhe. The following methods are relatively preferable for comparison among the methods: go to watch the posteroanterior sighting rod of picture with eyes and its part that stretches out above the picture experiences and "remembers" the neural state of vision of watching this sighting rod upper segment, from last sighting rod down until the sight is kept off by the picture, makes the neural state that is in the original sighting rod of vision all the time of vision, just at this moment sees the three-dimensional form that the picture represents like. However, when the sight line is shifted to see the lower picture, the state of the optic nerve of the picture is changed to only watch the picture, and it is not easy to watch a marker post which is not seen actually, so that the formation of stereoscopic vision by the method is not proved.

Recently, a patent (publication No. CN 111123550 a) that has been published by us has proposed a better method for viewing repetitive pattern stereograms, namely, establishing an induction imaging system comprising: the repetitive pattern stereo picture, the transparent reflecting sheet which is covered in front of the picture and is transparent and has reflection function to light, and a lamp string group; the lamp string group consists of one lamp string or a plurality of lamp strings which are parallel in the direction, and each lamp string consists of a plurality of identical lamp beads which are arranged at equal intervals from left to right; each light string is parallel to the three-dimensional picture, and the distance between the light string and the picture is at least 100 mm; the relative positions of the lamp string group, the three-dimensional picture and the two eyes of the observer meet the following conditions: the light rays emitted by each lamp string form mirror symmetry lamp string virtual images through the reflection of the transparent reflector, both eyes of an observer can see all lamp string virtual images, the sight of the virtual images of all lamp beads in the lamp string is intersected with the picture of the stereoscopic picture, and the intersection point of the sight is called the 'apparent position' of the lamp bead virtual images in the picture; the induction imaging system induces the viewer to watch the back of the three-dimensional picture by the light string virtual image behind the picture, and the viewer sees the picture pattern at the same time, thereby providing good conditions for forming three-dimensional vision.

The solution of this patent disclosed also gives several specific designs to the structure of the light string set. The 'lamp string' formed by a plurality of lamp beads is adopted instead of a single 'point lamp' for inducing imaging, and the lamp string has a plurality of advantages, for example, the lamp beads in the lamp string are densely distributed, and the lamp string is longer, so that the pattern spots of the picture can be compared with the lamp beads nearby, and the stereoscopic vision is convenient to form; for another example, the virtual image of a string actually constitutes a new repeated pattern stereograph, so that it can also form deep-diameter stereograph in vision, and said stereograph is simple and bright, and is positioned at the far place behind the picture, and it also has a good induction action for stereograph imaging of picture. The solution described in this patent is very sensitive to the formation of stereoscopic vision for persons who have a clear desire to see stereoscopic images from a stereoscopic representation (and thus have a sense of patience).

However, in some situations, a person viewing a repetitive pattern stereograph may not have a clear desire to see the stereogram, for example, in the presence of a billboard made with such a picture, many passers-by may only see a few eyes at any time for such a somewhat odd picture, and habitually their eyes may only see the middle area of the picture corresponding to the eye height; however, the light string in the above patent technical solution can only be installed at the upper and lower edges of the picture (otherwise, it may block the view of the picture from both eyes), as shown in fig. 4 (note: fig. 4 and the aforementioned fig. 1 to 3 are both cited from patent 111123550 a), so that the observer who only sees the middle area of the picture cannot see the light string virtual image, and the light string virtual image cannot play an inducing role, which is a serious problem in the above patent; another problem with said patent is that if a virtual light string image is visible superimposed on the pictorial image, the bright spots of the virtual light string image are actually smeared to the cleanliness of the pictorial image, which is not intended for artistic appreciation of the picture, and therefore should be minimized.

SUMMERY OF THE UTILITY MODEL

(II) selection of lamp-to-picture distance: theoretically, when the distance between the lamp and the picturezThis will best induce stereoscopic imaging when compared to the maximum depth of the avatar of a repeating pattern stereogram, but this may be such that the distance iszHaving a size of a few meters, such a large distance is only possible in very special circumstances, such as a picture in a room, where the lamp can be mounted on the wall opposite the picture. Experiments show that the distance between the lamp and the picturezIf not too small, there is still a relatively good effect of inducing stereoscopic imaging: (zAt least 150 mm); for the situation that the lamp supporting rod is arranged at the edge of the picture, the distance between the lamp and the picture can be taken in consideration of the effect of three-dimensional imaging and the beautiful appearance of the devicezDistance from eye to pictures1/6-1/4, such assWhen the distance to the picture is about 1600 mm, the distance from the lamp arranged at the left edge and the right edge of the picture to the picture is 270 mm, and the distance from the lamp arranged at the left edge and the right edge of the picture to the picture is 340 mm.

(III) when viewing the repetitive pattern stereoscopic picture, since the interval of the pattern spots of the pattern spot string determines the depth of the stereoscopic picture, it is possible to form a stereoscopic vision from the picture pattern in a range of the stereoscopic picture only if the interval of the pattern spots can be clearly recognized for the pattern spot string in the range; when the eyes of the person do not rotate basically, the visual field range of the picture pattern which can be seen clearly is about 20 in the horizontal direction^oThis range is called "visual field capable of simultaneously seeing the patterns", and if all "visual fields capable of simultaneously seeing the patterns" are added together when the eyeball rotates, the total visual field range is about 100^o(ii) a Therefore, when the horizontal length of the stereograph is very large, the eyes need to be rotated, the' view field capable of seeing the pattern clearly can be transferred once along the horizontal direction, a local stereo figure is formed from the parts of the picture, and a complete stereo figure is formed by integrating the memorized impressions; based on the above-mentioned reason, the measure of 'synchronously and periodically lighting a pair of lamps' in the above technical solution (two), (four), (six) also meets the following requirements: (a) the peak brightness of the blinking light of the pair of lights is high enough that it is impossible for an observer to overlook either of the two bright blinking light virtual images in subconscious (it is impossible to do so) while viewing the pictureStaring at only one look), (b) the opening angle of the virtual images of the two lamps of the pair of lamps with respect to the eye is less than 20^oSo as to ensure that the two lamp virtual images can be positioned in a 'view field capable of seeing the patterns simultaneously'; when the two conditions (a) and (b) are both satisfied, the observer can see the two lamp virtual images behind the picture at the same time, and can see the picture pattern between the two lamp virtual images clearly, so that a foundation is laid for forming stereoscopic vision. In practice, the angle of the two lamp virtual images of a pair of lamps relative to the eyes is less than 20^oThis corresponds to the distance between the two apparent positions of the virtual images of the two lamps in the picture being less than 1/3 times the eye-to-picture distance, so that the distance between the perpendicular projections of the two lamps to the picture is less than about 0.4 times the eye-to-picture distance. In the above technical solution, two lamps ' emit light in a blinking manner for a period of time in one period, and emit light at a constant brightness for the rest of time, in a specific implementation manner, the period of time of blinking and emitting light in one period may be 5 to 10 seconds, the length of the period of time depends on how easily the related picture pattern is stereoscopic, and the ' remaining time of the period of time of the blinking and emitting light at a constant brightness ' is used for reducing the attention of the observer to two lamp virtual images themselves and increasing the attention to the picture pattern between the two lamp virtual images, or for shifting the attention to another pair of blinking and emitting lamp virtual images and the related picture pattern.

(IV) when the conditions (a) and (b) are both met, under the induction of a pair of lamp virtual images which synchronously flicker and emit light, an observer sees the two lamp virtual images and also clearly sees the picture pattern between the two lamp virtual images; however, there is a process from the clear picture pattern to the formation of stereoscopic vision (seeing the corresponding stereoscopic image), which is a process of carrying out a huge amount of information processing by the brain visual nerve center, the time spent in the process is greatly different due to different imaging difficulties of the stereoscopic picture, some are only a moment, and some are as long as six seconds and seven seconds, a fuzzy relief type image is seen in one second or two seconds, and then the image is gradually changed into a clear stereoscopic image with a large depth diameter after four seconds and five seconds; therefore, there is no clear purpose for oneOnly a person who accidentally sees the picture needs to insist on seeing the picture for one or two seconds to see the initial stereo image, and then the person is driven to see the picture continuously by curiosity, so that the person can see the stereo image finally; therefore, trying to attract people who watch the picture to make the people watch the picture for 0.5-2 seconds, is an important problem in widening the field of the repeated pattern stereoscopic picture. In the above technical solution, (seven) said a method, that is, the frequency and brightness of the flickering light of a pair of lamps holding a certain area of the picture are changed, for example, the flickering light of the pair of lamps has an "drumbeat" moving beat, which should attract the observer to watch the pattern of the area for a long time; in the technical scheme, (eight), (nine) and (ten) in the light letting stringnThe lamps are sequentially flickered, which is equivalent to the movement of the single flickered lamp, and the effect of prolonging the picture-watching time of the observer is achieved, and the vision of the observer moves backwards along with the light spot, which also contributes to the formation of stereoscopic vision. There are also more effective ways of extending the viewing time, for example by making the picture pattern between two flashing virtual lamp images also change brightness or colour, which is a considerable attraction for the viewer, but this is too cumbersome to achieve and does not seem necessary.

(V) transverse length of picture elementHAfter the determination, the distance from the eyes to the picture is not too small due to the limitation of 'the visual field capable of seeing the pattern clearly at the same time', but too large causes the problem that the pattern is not clear; when the structures described in the technical scheme (I) and (II) are adopted, the distance from the eyes to the picturesIs generally preferably asH2 to 2.5 times higher than that of the other, e.g.HMeasured when = 600 mms = 1200 mm; when the structures described in the technical schemes (three) and (four) are adopted, the distancesIs generally preferably asH1.3 to 1.5 times of, for exampleHMeasured when = 1200 mms= 1600 mm; in this configuration, the left two lamps L_{Left side of}And L_{Upper left side}Is responsible for the task of image-forming induction of the upper left part of the picture, and two lamps L on the right_{Right side}And L_{Upper right side}Is responsible for the task of image-guided imaging of the upper right part of the picture, so that this structure is for the same distancesThe lateral length of the picture can be doubled. In the technical scheme (Fifth) and sixth, the vertical length of the picture can be doubled, because the upper and lower lamp pairs are respectively responsible for the induced imaging tasks of the upper and lower parts of the picture. The vertical length of the stereograph can be made larger by using the 'comparison-expansion effect for forming stereo vision', and the stereograph is made into a structure in which the patterns of all lines are internally associated from top to bottom, for example, a plurality of penetrating lines from top to bottom are formed, so that the 'comparison-expansion effect' can be exerted strongly, and all lines are driven by a few lines to form stereo vision.

(VI) according to the theory behind the technical scheme, some flexible ways can be adopted, for example, in the aspect of arrangement of the lamps, if the picture is transversely long, a plurality of pairs of lamps can be arranged on the upper edge, if the picture is vertically long, a plurality of lamps can be respectively arranged on the left edge and the right edge, and if the environment allows, the lamps can also be arranged on the lower edge; particularly, a 'lamp pair' can be specially arranged for a special area of the picture to bear the stereo imaging task, for example, the stereo picture shown in fig. 3, the lower area where the lines 3.3 and 3.4 are located is most easy to form stereo vision, and lamps can be arranged on the left side and the right side or the lower side of the area to induce the area to carry out the stereo imaging in advance, so that the whole picture can be driven to carry out the stereo imaging; for example, in the aspect of lighting lamps, some lamps can be arranged to flash and light in a certain sequence, and the eyes of the viewer are guided to move along with the virtual light spots of the lamps so as to scan the area patterns of the picture.

(VII) the method described In (IV) above is to make stereoscopic vision by illuminating the viewer in a "pattern" of a pair of lamps to attract the viewer to extend the time of viewing the picture; however, this solution can extend only for a limited time, and if the picture is not stereoscopically visible for this limited time, the viewer may get lost. Therefore, in order to effectively use a three-dimensional picture for advertisement, etc., the picture itself needs to be designed, and the picture is designed from the viewpoint of easy formation of three-dimensional vision in addition to highlighting the subject of advertisement. The following strategy can be adopted overall: selecting a small area of the picture, and specially designing the pattern of the small area to make the stereo imaging specialThe method is easy, and the paired lamps arranged in the area are used for the stereo imaging task of the area picture, once the stereo imaging is realized, the area picture is internally related with the rest part of the picture in length and breadth, so that the 'comparison-expansion effect' is exerted strongly, and the stereo imaging of the local area is rapidly expanded into the stereo imaging of the whole picture. The key point here is how to design the picture for the selected area to be easily stereoscopic, which is done as follows: the opening angle of the size of the area relative to the eyes is less than 20^oSo that the whole area can be contained in a 'visual field capable of seeing the pattern at the same time'; secondly, all the image spot strings in the region have strict periodicity, and each image spot string at least comprises 4 image spot intervals; thirdly, the area has a high occupation ratio of all the image spots of all the graphic primitives in the transverse direction, namely, the blank area without the image is small; the picture in this area is particularly obvious: the brightness is large, the contrast is large, the light-dark contrast and the color contrast are strong, the pattern spots are large, whether the patterns of the pattern spots are the same or different can be easily judged, the periodicity of the picture is obvious, so that the signal of the picture information can strongly stimulate the subconscious of a viewer, and the viewer can clearly see the picture without special attention; the picture in this area is quite simple: the pattern of the graphic primitive is simple, the lines are simple and clear, the color is monotonous, the types of the graphic spots in the graphic primitive are few, the arrangement of the graphic spots is simple, and the picture is neat and disorderly, so that the amount of information processing required by a brain center is small, and the processing time is natural and short; preferably, the area contains two spot strings with different spot interval parameters, so that three-dimensional images with different depth diameters can be seen in the area. If the above items are well done, the stereoscopic image can be seen from the picture pattern controlled by a pair of virtual images of the lamps, which can be completely realized in a moment.

The effect of the induced imaging system of the present invention for viewing the repeated pattern stereograph will be described below.

For viewing three-dimensional objects at ordinary times, people with normal stereoscopic vision capacity account for about 85% of the total number of people. When the repeated pattern stereograph is viewed, the difficulty of forming stereoscopic vision is obviously much higher than that of viewing a three-dimensional object. Preliminary experiments show that by applying the induction imaging system on the repeated pattern stereograph according to the above, under the condition of fully optimizing conditions, no matter whether the person who observes the stereograph has strong desire, more than 60% of people can form stereoscopic vision. In fact, a display with a reflective screen is used for playing a plurality of repeated pattern stereographs, and two flashlights are used for lighting one picture, so that the effect of stereo imaging can be immediately experienced. In addition, the utility model discloses a punctiform lamp comes the induced formation of image, and only several lamp virtual image bright spots superpose on the picture shape, and it is much less to the clean stained of picture obviously than the lamp cluster, can also consider to make these several lamp virtual image bright spots subtly a part of the content that the picture expressed, just become stained for helping.

The induction imaging system is used for watching the repeated pattern stereograph, once the stereo vision is formed, even if the light is turned off, the stereo image can still be seen as long as the vision is not shifted. After seeing the stereo image, two eyes can approach to the picture without limit, so that the stereo vision can not be lost, and the detail of each local part of the stereo image can be seen more clearly, just like seeing the stereo object from far to near at ordinary times. The repeated pattern stereograph can be used as a single frame picture to be made into an animation picture, and after a viewer forms a stereoscopic vision by using the first frame picture, the stereoscopic vision can be continuously maintained and the dynamic stereoscopic image can be seen as long as the motion change of the stereoscopic image is not too fast.

The repeated pattern stereo picture and the matched induction imaging system are applied to the aspects of advertising boards, artistic fresco and the like, the manufacture is simple, the cost is very low, and the stereo picture can be vividly and interestingly displayed to people, so that the repeated pattern stereo picture can possibly become a new advertising mode and an artistic appreciation mode which are loved by people.
