Description

Technical Field

[0001] The present invention relates to the field of optical imaging, and in particular to a surround imaging device and method thereof. Background Art

[0002] Today, people are increasingly demanding immersive visual experiences. For example, current dome displays and annular (or surround) screen displays can provide those surrounded with a strong visual immersion experience. However, these traditional technologies are currently limited by screen size and venue space size, and are very expensive. In addition, these traditional surround screens actually create an opaque, surround-wrapped three-dimensional space. They cannot display both surround images and transparent images (i.e., real objects can be seen through the transparent images). The images displayed by these traditional image surround technologies cannot be integrated with the real scene behind the screen. Since the real objects behind the images cannot be seen and there is no physical background reference, the depth, three-dimensionality, and immersion of the images are weakened. In addition, virtual three-dimensional images cannot be displayed from both the front and back at the same time, which is a limitation. Summary of the Invention

[0018] According to the optical reflection principle, the reflection imaging analysis of the present invention is as follows: As Figures 1 to 12 shown, the first reflector 1 and the second reflector 2 are used as reflection carriers, and the shown reflectors can be plane mirrors or curved mirrors. The light emitted from the first screen 3 is reflected between the first reflector 1 and the second reflector 2 (back and forth) to form (generate) the virtual image set A and the virtual image set B. The virtual image set A = {A1, A2,..., A n}, each element in the set A represents a reflected virtual image, and there are n elements in the set A (that is, the number of virtual images is n). Among them, the virtual image A1 is the first virtual image generated by the first screen 3 using the first reflector 1 as the reflection carrier, and the virtual image A n refers to the nth virtual image in the virtual image set A, and A n is the last generated virtual image in the virtual image set A. Similarly, the virtual image set B = {B1, B2,..., B n}; among them, the virtual image B1 refers to the first virtual image generated by the first screen 3 using the second reflector 2 as the reflection carrier, and the virtual image B n refers to the nth virtual image in the virtual image set B, and the virtual image B n is the last generated virtual image in the virtual image set B. The order of the virtual images in the virtual image set described in the present invention is arranged in the chronological order of the generation of the corresponding virtual images, that is, the virtual images A1 and B1 are the corresponding first generated virtual images, that is, the virtual images A n and the virtual image B n are the last generated virtual images in the corresponding virtual image sets. According to the optical reflection imaging law, the virtual image A n-1 generates a corresponding virtual image B by being reflected at a corresponding position using the second reflector 2 as the reflector n , for example, when n = 12, then the virtual image A 11 = the virtual image A 12-1 , that is, A 11 generates a corresponding virtual image B at a corresponding position using the second reflector 2 as the reflector 11 , where the virtual image A 12and virtual image B 12 The corresponding virtual image is finally generated, the virtual image A n-1 It refers to the n-1th virtual image in the set A (i.e., the previous virtual image of the nth virtual image). Similarly, the virtual image B n-1 By using the reflector 1 as a reflection carrier, a corresponding virtual image A is generated at the corresponding position. n , for example, when n=12, the virtual image B 11 The first reflector 1 is used as a reflective carrier to generate a corresponding virtual image A at a corresponding position. 12 , where the virtual image B 12 and virtual image A 12 It is the corresponding virtual image generated at last. The virtual image B n-1 It refers to the n-1th virtual image in the set B (i.e., the previous virtual image of the nth virtual image).

[0019] like Figure 1 、 Figure 8 and Figure 9 As shown, the virtual image set F={F1, F2, F3…,F m}, m is a natural number, F m is the mth virtual image, and the virtual images in the virtual image set F are virtual images corresponding to the first reflector 1, wherein the virtual image F1 corresponds to the first virtual principal optical axis 42, the virtual image F2 corresponds to the second virtual principal optical axis 43, and the virtual image F3 corresponds to the third virtual principal optical axis 44; the virtual images A2 and A3 correspond to the virtual image F1, the virtual images A4 and A5 correspond to the virtual image F2, the virtual images A6 and A7 correspond to the virtual image F3, and so on; the set of angles formed by the principal optical axes (or corresponding normals) of the virtual images in the virtual image set F and the second principal optical axis 34 (or the second normal 12) is γ={γ1,γ2,…,γ m}, where m is a natural number, angle γ1 = α + 2α, angle γ2 = α + 4α, angle γ3 = α + 6α, angle γ4 = α + 8α, γ5 = α + 10α, that is, when the value of the angle α increases, the angle γ 1、 Angle γ 2、 Angle γ 3、The values of angle γ4 and angle γ5 increase, and so on; therefore, the set γ is an arithmetic progression, monotonically increasing, and according to the law of optical imaging, it is concluded that the virtual images in the virtual image set A are generated in chronological order and arranged in a circular manner. Among them, virtual image A2 and virtual image A3 are a virtual image group, virtual image A4 and virtual image A5 are a virtual image group, virtual image A6 and virtual image A7 are a virtual image group, and so on. Therefore, the direction of the normal vector corresponding to each virtual image group in set A is deflected by an angle of 2α in the corresponding direction, so that the virtual image can be arranged in a circular distribution around the corresponding axis, that is, the virtual images in the virtual image set A are combined and arranged into a circular visual effect, forming a unique three-dimensional surround visual space. Similarly, the virtual images in the virtual image set B are also combined and arranged into a circular effect. For example, Figure 1 As shown, the virtual images in set A are within a first range 21, and the virtual images in set B are within a second range 22. The virtual images in set A can be seen arranged in a ring along the first direction 11, while the virtual images in set B can be seen arranged in a ring along the second direction 32. The first range 21 or the second range 22 refers to the three-dimensional spatial range on one side of the first tangent plane 16 or the second tangent plane 25.

[0020] In summary, the number n of virtual images formed by the first screen 3 within the first range 21 is the integer part of the quotient of 180° / α (for example, the integer part is a), or the integer part of the quotient of 180° / α (for example, the integer part is a) plus 1, which is the corresponding number of virtual images n, that is, n=a+1; for example, when the integer part of the quotient of 180° / α is a and the decimal part is 0, the corresponding number of virtual images n=a, when the angle α = 15°, n=180° / 15°=12, that is, the corresponding number of virtual images n=12, that is, virtual image A n = virtual image A 12 , at this time, the last virtual image generated in set A is a complete reflected virtual image; for example, when the integer part of the quotient of 180° / α is a and the decimal part is not 0, the number of virtual images n=a+1, when α angle = 19°, 180° / 19°=9.4736, that is, the number of corresponding virtual images n=9+1=10, virtual image A n = virtual image A 10 At this time, the last virtual image generated in the virtual image set A is a reflection virtual image that is not completely generated (displayed). Point M is a point on the virtual image A1, and point M′ is a point on the virtual image A1. nA point on the tangent plane 16, point M and point M' are two corresponding points, the distance between line segment MM' is L (that is, the distance between the first virtual image generated and the last virtual image generated). When the value of angle α is divisible by 180°, line segment MM' is parallel to the first tangent plane 16; when angle α is equal to 0°, the value of the number n of virtual images is infinite, the last virtual image cannot be determined, and the shape formed by the arrangement of its virtual images is not a ring. The last virtual image is at infinity, that is, at this time, virtual image A1 and virtual image A n The distance L is infinite and cannot be determined. The size of the angle α is used to determine the number n of virtual images in the virtual image set A or the virtual image set B. When the angle α increases, the number n of virtual images decreases accordingly. The adjustment of the number n of virtual images can meet the convenience of adjusting the number of virtual images and meet different visual effect requirements. The visual effects include: the visual effect presented by the density of the virtual image distribution in the virtual image set A or the virtual image set B. The density refers to the density (virtual image density) of all virtual images generated in the space of the first range 21. The size of the angle α is also used to make the corresponding direction of the first virtual image (i.e., virtual image A1) in the virtual image set A, the last virtual image (i.e., virtual image A n ) and the corresponding directions of other corresponding virtual images produce different directions, so that the corresponding virtual images produce a unique surrounding arrangement visual effect. When the value of α changes, the virtual image A1 and the virtual image A n The corresponding orientation changes accordingly, and the corresponding orientation refers to the direction of the normal vector corresponding to the virtual image itself. Point N is a point on the surrounding axis, point P is a point on the surface of the first screen 3, and the distance of line segment NP is W, where W < 200 meters. According to the optical reflection imaging law, when the value of W increases or decreases, the value of L also increases or decreases. The magnitude of distance W is also used to control the magnitude of distance L. In addition, 2W>L, the magnitude of distance W is used to control the magnitude of distance L. When distance W increases, distance L increases. The magnitude of distance W of line segment NP is used to adjust or determine the viewing distance between viewer 19 or viewer 18 and the corresponding virtual image (e.g., the virtual image in set A and set B). This can conveniently determine the distribution range of the virtual images in virtual image set A and virtual image set B, meeting different visual effect requirements.

[0021] In summary, it can be concluded that if Figure 1 、 Figure 8 and Figure 9 When the first reflector 1 and the second reflector 2 are plane mirrors and / or curved mirrors, the virtual images (virtual images in the virtual image set A or the virtual image set B) generated by reflection in the present invention are all arranged and distributed in a surrounding manner.

[0022] The beneficial effects of the present invention are: achieving real-time adjustment of the corresponding normal orientation of each virtual image in the virtual image set A or virtual image set B, and the virtual image generated by the reflection can display a transparent (similar to a traditional phantom imaging effect) or opaque, annularly arranged stereoscopic image effect (which can also be used in combination with stereoscopic equipment and corresponding technologies to produce a more realistic three-dimensional immersive effect), forming a semi-enclosed (or semi-enclosed) or fully enclosed (or fully enclosed) surround virtual stereoscopic image, ultimately producing a wraparound virtual stereoscopic space that can surround (surround) the observer within the virtual stereoscopic image, thereby providing the observer with a strong visual immersion experience. By setting corresponding display objects (such as the first display object, 78. the second display object, or 79. the third display object), the surround virtual image generated by the corresponding display object and the image displayed on the display screen can jointly form a set of virtual and real dual-layer surround stereoscopic images, providing an extremely strong visual immersion experience. By determining the size of the corresponding angle α, the number n of virtual images in virtual image set A and virtual image set B can be determined in real time (for example, as angle α decreases, the number n of virtual images generated increases). This allows for real-time determination or dynamic control of the density of the virtual images, effectively enhancing the visual appeal and interest. By determining the size of the corresponding angle α and the size of distance W, and thereby controlling the size of distance L, the size of the rings formed by the virtual images in virtual image set A and virtual image set B can be controlled in real time, meeting the requirements of different venues. By controlling the size of angle α, the number of virtual images displayed on the corresponding screen can be flexibly controlled, saving corresponding screen material and using fewer screens to display the effect of multiple virtual screens. Since multiple virtual image effects can be displayed, the virtual images do not occupy space, meaning that a smaller space (or smaller area) can be used to display image effects that would require a larger space (or larger area). When the reflectors are all plane mirrors, each virtual image in virtual image set A or virtual image set B can be made to produce a virtual image of the same size. When the reflectors include curved mirrors, each virtual image in virtual image set A or virtual image set B can be made to produce virtual images of different sizes, with a magnified effect, thus meeting the flexible usage requirements of different scenarios. The audience can simultaneously view the virtual stereoscopic image from both the front (e.g., first direction 11) and the back (e.g., second direction 32). Furthermore, the present invention allows for naked-eye observation of stereoscopic images (parallax-type) and the viewing of multi-layered stereoscopic images (non-parallax-type), further enhancing the visual immersion experience. The present invention has broad application in immersive experience fields such as exhibitions, amusement rides, intelligent interactions, and the metaverse.

DETAILED DESCRIPTION

[0045] The present invention will be explained in detail through the following embodiments with reference to the accompanying drawings.

[0046] The following is embodiment 1 of the present invention. Figure 1 、 Figure 2 and Figure 13 As shown, the first reflector 1, the second reflector 2, and the first screen 3 are fixed by a support frame and set vertically on the ground; the first reflector 1 and the reflector 2 are two flat coated glasses (i.e., the glass surface is coated with a metal film, and the metal film is a layer of reflective film). The reflective surfaces of the two coated glasses are set to an angle α, α=15°, the first tangent plane 16 and the second tangent plane 25 intersect at the first surround axis 9, point N is a point on the first surround axis 9, point P is a point on the surface of the first screen 3, the distance of the line segment NP is W, and the line segment NP is perpendicular to the first surround axis 9, point b and point d are two points on the reflective surface of the first reflector 1, and the first reflector 1 is perpendicular to the first surround axis 9. Among all straight lines connecting any two points on the reflective surface, line segment bd has the longest distance, and the distance of line segment bd is greater than 0.2W. For example, W is equal to 2 meters, and the distance of line segment bd is greater than 0.4 meters. Point e and point f are two points on the reflective surface of the second reflector 2. Among all straight lines connecting any two points on the reflective surface of the second reflector 2, line segment ef has the longest distance, and the distance of line segment ef is greater than 0.2W. The edge surface 80 of the reflector is brought into contact with a black substance, for example, by painting the edge thickness portion of the glass (for example, the edge surface 80) black with black paint. The black paint is used to reduce the brightness of the edge portion of the glass and reduce the interference of reflected light on the eyes. The first screen 3 is a liquid crystal screen, for example Figure 1 According to the imaging principle of optical reflection, the virtual image set A={A1,A2,…,A n}, the virtual image set B={B1,B2,…,B n}, determine the number of virtual images in the virtual image set A and the virtual image set B as n=180° / 15°=12, that is, generate 24 corresponding complete virtual images in the first range 21 and the second range 22, and the virtual images generated in the first range 21 (the virtual images in the virtual image set A) are: A1, A2, A3, A4, A5, A6, A7, A8, A9, A 10 , A 11, A 12 , that is, the virtual image set A={A1,A2,…,A 12}, the virtual images generated by the second range 22 (the virtual images in the virtual image set B) are: B1, B2, B3, B4, B5, B6, B7, B8, B9, B 10 ,B 11 ,B 12 , that is, the virtual image set B={B1,B2,…,B 12},like Figure 1 As shown, according to the above reflection imaging analysis, the 24 virtual images are arranged in a surrounding distribution. The first observer 6 observes along the first direction 11 and can see the virtual images A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A111, A12, A3, A4, A5, A6, A7, A8, A9, A10, A112, A12, A3, A4, A5, A6, A7, A8, A9, A10, A113, A114, A125, A126, A127, A128, A129, A130, A131, A132, A133, A134, A135, A136, A137, A138, A139, A140, A141, A142, A143, A144, A1 10 、A 11 and A 12 , and can also be observed in the second direction 32, and virtual images B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B3, B4, B5, B6, B7, B8, B9, B12, B13, B14, B15, B16, B17, B18, B19, B20, B21, B22, B23, B 10 、B 11 and B 12 , the 24 virtual images in the virtual image set A and the virtual image set B are seen to be distributed in a circular manner (with point N as the center, arranged in a circular manner); in addition, the third observer 19 observes in the first direction 11, and sees part of the virtual images in the virtual image set A through the first reflector 1, such as virtual images A1, A2, A3, A4, A5, and A6, and sees that these virtual images are distributed in a semi-circular manner (with point N as the center, arranged in a semi-circular manner); the second observer 18 observes in the second direction 32, and can see part of the virtual images in the virtual image set B through the second reflector 2, such as virtual images B1, B2, B3, B4, B5, and B6, and sees that these virtual images are distributed in a semi-circular manner (with point N as the center, arranged in a semi-circular manner). Set point M and point M′, the distance between line segment MM′ is L, point M is a point on the virtual image A1, and point M′ is a point on the virtual image A1. n A point on the first screen 3, point M and point M' are two corresponding points; when a light ray emitted from a point on the first screen 3 is reflected to form a light ray, the reverse extension line of the light ray will coincide with the virtual image A1 and the virtual image A n If they intersect at two points respectively, then these two points can be point M and point M', that is, these two points are corresponding points; according to the law of optical reflection, set point M and point P are also two corresponding points, that is, the distance of line segment NP is equal to the distance of line segment NM, and the distance from point P to the first tangent plane 16 is set to K. According to the Pythagorean theorem, , Right now, . The first observer 6, the second observer 18 and the third observer 19 can all watch virtual images with a highly immersive surround arrangement effect. Since the first reflector 1 and the second reflector 2 are both translucent, the observers can see that the virtual images in the virtual image set A and the virtual images in the virtual image set B are all transparent, thereby achieving an effect of virtual-real fusion of transparent virtual images with the surrounding real objects on the site or the real objects in the front, back, left, right, up and down directions. That is, by using the real objects in the front, back, left, right, up and down directions as reference objects, a unique and strong surround-type fusion of virtual and real immersive experience is produced. This type of effect has not been produced before the present invention. This embodiment uses only one display screen to generate multiple identical virtual display screens, which expands the space for image display and ultimately produces a surround-type virtual three-dimensional space. While improving the immersive experience and sense of mystery, it saves costs.

[0047] The following is embodiment 2 of the present invention. Figure 3 The embodiment of the present invention is as follows: on the basis of Example 1, a third reflector 13, a fourth reflector 14, a second screen 15, a first exhibit 77, a second exhibit 78, and a third exhibit 79 are added and fixed by a support frame to build a holographic surround exhibition stand or holographic surround stage that integrates the virtual and the real. The first reflector 1, the second reflector 2, the third reflector 13, the fourth reflector 14, the first screen 3 (a liquid crystal screen), and the second screen 15 (a liquid crystal screen) are fixed and placed perpendicular to the ground; the third reflector 13 and the fourth reflector 14 are transparent plane reflectors coated with a metal film (reflective film). The reflective surface of the first reflector 1 and the reflective surface of the third reflector 13 are parallel to each other and arranged on the same plane. The fourth reflector 14 forms an angle β with the third reflector 13, β = 15°. According to the analysis of Example 1, Similarly, when the second observer 18 observes along the second direction 32, he can see the virtual images in the virtual image set D through the fourth reflector 14, and see part of the virtual images in the virtual image set B through the second reflector 2; the third observer 19 observes along the first direction 11, and sees part of the virtual images in the virtual image set A through the first reflector 1, and sees the virtual images in the virtual image set C through the third reflector 13; the virtual images in the virtual image set C and the virtual image set A are distributed in a circular manner (with point N as the center). Wherein the virtual image set C = {C1, C2, ..., C r}, virtual image set D={D1,D2,…,D r}, wherein r=12. The first exhibit 77, the second exhibit 78 and the third exhibit 79 are as shown in FIG. Figure 3The three exhibits are illuminated by light. According to the above light reflection analysis, the first exhibit 77, the second exhibit 78 and the third exhibit 79 respectively generate three corresponding virtual image sets, which are virtual image sets H={H1, H2, ..., H 12}, virtual image set E={E1,E2,…,E 12}, virtual image set Q = {Q1, Q2}, the virtual images in the three virtual image sets are arranged in a surrounding manner, and these virtual images can also correspondingly display the appearance effects of the first exhibit 77, the second exhibit 78 and the third exhibit 79 at different angles; the virtual images in the virtual image set H, the virtual image set E and the virtual image set Q (forming the second layer of images), and the virtual images in the virtual image set A and the virtual image set C (forming the first layer of images) together form a set of multi-layer surround virtual and real fusion stereoscopic images with front and back distances, ultimately generating a surround-wrapped virtual three-dimensional space, thereby creating a unique visual immersive experience.

[0048] The following is embodiment 3 of the present invention. Figure 4 and Figure 5On the basis of Example 2, a refractive body 7 is added. The refractive body 7 is a transparent square container filled with water. The second reflector 2 and the fourth reflector 14 are placed in the container so that the reflective surfaces of the second reflector 2 and the fourth reflector 14 are in contact with the water. The first screen 3 (a liquid crystal screen) and the second screen 15 (a liquid crystal screen) are placed outside the square container. The second reflector 2 is set in the refractive body 7. The reflective surface of the second reflector 2 is in contact with the refractive body 7. The refractive surface EFTZ is located between the second reflector 2 and the first screen 3. The reflector 2 is located between the refractive surface FTSR and the refractive surface EPQZ; the reflective surface of the fourth reflector 14 contacts the refractive body 7, the refractive surface SRPQ is located between the fourth reflector 14 and the first screen 3, the fourth reflector 14 is located between the refractive surface FTSR and the refractive surface EPQZ, the fourth reflector 14 is 75 degrees to the refractive surface SRPQ, the refractive surface SRPQ is parallel to the refractive surface EFTZ, the refractive surface FTSR is parallel to the refractive surface EPQZ, and the refractive surface FTSR is 15 degrees to the fourth reflector 14. According to invention patent CN201110080894.6, the first screen 3 and the second screen 15 will be hidden, that is, when the second observer 18 observes in the second direction 32, he can see part of the virtual image in the surrounding virtual image set D and part of the virtual image in the virtual image set B, but cannot see the first screen 3 and the second screen 15; when the third observer 19 observes in the first direction 11, he can see part of the virtual image in the surrounding virtual image set C and part of the virtual image in the virtual image set A, but cannot see the first screen 3 and the second screen 15; that is, the second observer 18 and the third observer 19 cannot see the first screen, which increases the mystery of the imaging and the novel and unique display effect.

[0049] The following is Example 4 of the present invention. Figure 6 On the basis of Example 1, a fifth reflector 23 and a sixth reflector 24 are added, wherein the fifth reflector 23 is parallel to the sixth reflector 24, and the first reflector 1 is perpendicular to the fifth reflector 23 and the sixth reflector 24, respectively, so that the virtual image set {A1, A2, ..., A 12} and the virtual image set {B1, B2, ..., B 12 The virtual image in the image is reflected by the fifth reflector 23 and the sixth reflector 24 and formed at corresponding positions, so that the second observer 18 and the third observer 19 can see more virtual images, thereby producing a unique visual effect.

[0050] The following is Example 5 of the present invention. On the basis of Example 2, a power module composed of a motor is added to rotate the first reflector 1 and the third reflector 13, which can change the size of the angle α, thereby causing the corresponding number of virtual images to change in real time.

[0051] The following is embodiment 6 of the present invention. Figure 8 、 Figure 14 and Figure 16 As shown, based on Example 1, the plane mirror of the second reflector 2 is replaced with a curved mirror. The curved mirror is a transparent concave mirror with a metal film (i.e., a reflective film) coated on its surface. The first normal 8 of the reflector 1 (i.e., the plane mirror) forms an angle α with the second principal optical axis 34 of the curved mirror (concave mirror), α=15°. The object distance between the first screen 3 and the curved mirror is u=0.5 meters. The focal length of the curved mirror is u=5 meters. The first tangent plane 16 and the third plane 37 intersect at the third surround axis 50. The third plane 37 is a plane perpendicular to the first screen 3 and the curved mirror. The plane passing through the second reflector 2 and perpendicular to the second principal optical axis 34; point b and point d are two points on the reflective surface of the first reflector 1. Among all straight lines connecting any two points on the reflective surface of the first reflector 1, line segment bd has the longest distance, and the distance of line segment bd is greater than 0.2W; point e and point f are two points on the reflective surface of the second reflector 2. Among all straight lines connecting any two points on the reflective surface of the second reflector 2, line segment ef has the longest distance, and the distance of line segment ef is greater than 0.2W. Similarly, based on Example 1, according to the reflection imaging law of the concave mirror, the first screen 3 can be reflected by the first reflector 1 and the second reflector 2 (curved mirror) into two sets of virtual images, namely: virtual image set {A1, A2, ..., A 12} and the virtual image set {B1,B2,…,B 12 Since the second reflector 2 is a concave mirror, it has a magnifying effect. Therefore, the virtual image set {A1, A2, ..., A 12} and the virtual image set {B1,B2,…,B 12 The image in} can present an effect of magnifying the first screen 3 as a whole. According to Example 1, the virtual image can also form a surround effect.

[0052] The following is embodiment 7 of the present invention. Figure 9 and Figure 15 As shown, based on Example 1, the plane mirrors of the first reflector 1 and the second reflector 2 are replaced with curved mirrors, for example, the first reflector 1 is replaced with a cylindrical mirror (such as Figure 10As shown), the second reflector 2 is replaced with a concave mirror, and the corresponding reflective surface of the curved mirror is coated with a metal film; the first principal optical axis 33 of the reflector 1 (i.e., the cylindrical mirror) forms an angle α with the second principal optical axis 34 of the curved mirror (concave mirror), α=15°, the object distance between the first screen 3 and the curved mirror is u=0.5 meter, the focal length of the curved mirror is u=5 meters, the first principal optical axis 33 can be the principal optical axis passing through the center of the first reflector 1, points b and d are two points on the reflective surface of the first reflector 1, and among all straight lines connecting any two points on the reflective surface of the first reflector 1, the line segment bd has the longest distance, and the distance of the line segment bd is greater than 0.2W; points e and f are two points on the reflective surface of the second reflector 2, and among all straight lines connecting any two points on the reflective surface of the second reflector 2, the line segment ef has the longest distance, and the distance of the line segment ef is greater than 0.2W. According to the analysis of Example 1, similarly, the first screen 3 can be reflected into two sets of virtual images by the first reflector 1 (cylindrical mirror) and the second reflector 2 (concave mirror), namely: virtual image set {A1, A2, ..., A 12} and the virtual image set {B1,B2,…,B 12}, since the first reflector 1 is a cylindrical mirror, the virtual image set {A1, A2, ..., A 12} and the virtual image set {B1,B2,…,B 12 The image in the image can present the effect of horizontally enlarging the first screen 3, and also has the unique effect of surround imaging.

[0053] The following is Example 8 of the present invention. Based on Example 1, the first reflector 1 is replaced with a completely opaque total reflection mirror, that is, the generated virtual image set {A1, A2, ..., A 12} and the virtual image set {B1,B2,…,B 12 The virtual image in the mirror is opaque. Since it is a total reflection mirror, the reflection intensity of the reflected image can be improved. Since the total reflection mirror is opaque, the observer cannot see the real scene behind the virtual image through the virtual image, but the virtual image can produce an opaque three-dimensional surround effect.

[0054] The following is embodiment 9 of the present invention. Figure 11 On the basis of embodiment 1, a fifth reflector 45 is added. The object 4 is set between the first reflector 1, the second reflector 2 and the fifth reflector 45. The object 4 (for example, a display object) is illuminated by light. The fifth reflector 45 is a transparent reflector or an opaque reflector. Figure 11According to the law of optical reflection, the real object 4 can form a plurality of first reflected virtual images 47 arranged in a surrounding manner through the mutual reflection of the first reflector 1, the second reflector 2 and the fifth reflector 45, thereby forming a unique visual effect. The first reflected virtual image 47 is a virtual image of the first screen 3.

[0055] The following is embodiment 10 of the present invention. Figure 12 On the basis of Example 9, a sixth reflector 46 and / or a third screen 48 are added. The sixth reflector 46 is a transparent reflector or an opaque reflector. When the third screen 48 is included, the third screen 48 and the real object 4 are both arranged between the first reflector 1, the second reflector 2, the fifth reflector 45 and the sixth reflector 46. Similarly, according to the law of optical reflection, multiple first reflected virtual images 47 and second reflected virtual images 51 arranged in a surrounding manner can be formed to form a unique imaging effect. The second reflected virtual image 51 is a virtual image of the third screen 48, and the first reflected virtual image 47 is a virtual image of the real object 4. The sixth reflector 46 is a transparent reflector or an opaque reflector. When a display screen 48 is included, the third screen 48 and the real object 4 are both arranged between the first reflector 1, the second reflector 2, the fifth reflector 45 and the sixth reflector 46. Similarly, according to the law of optical reflection, a plurality of first reflective virtual images 47 and second reflective virtual images 51 arranged in a surrounding manner can be formed to form a unique imaging effect. The second reflective virtual image 51 is the virtual image of the third screen 48, and the first reflective virtual image 47 is the virtual image of the real object 4.

[0056] The following is Example 11 of the present invention. Figure 17 On the basis of Example 2, a seventh reflector 53 is added. The seventh reflector 53 is a transparent coated reflector or an opaque reflector, and can be a plane mirror or a concave mirror. The virtual images in the virtual image set B and the virtual images in the virtual image set D form a reflected virtual image set Q at corresponding positions through the seventh reflector 53. The virtual images in the virtual image set Q and the virtual images in the virtual image set A form a double-layer image with a front-to-back distance, thereby producing a strong three-dimensional immersive feeling.

[0057] The following is Example 12 of the present invention, which adds a third screen 52 on the basis of Example 2. Figure 18 and Figure 19As shown, the third screen 52 is set on one side of the reflector 1. According to the principle of optical reflection, the third screen 52 forms a virtual image set G={G1, G2, G3, G4, G5} through the reflection of the reflector 1 and the reflector 2. The virtual images in the virtual image set G will be superimposed in front of the virtual images in the virtual image set A and the virtual images in the virtual image set C to form two layers of virtual images. When the third observer 19 observes according to the first direction 11, he will see the two layers of virtual images with front and back layers at the same time, that is, the first layer of image refers to the virtual image in the virtual image set A and the virtual image in the virtual image set C, and the second layer of image refers to the virtual image in the virtual image set G. The two layers of virtual images seen together form a surrounding double-layer three-dimensional space, which can make the observer have a strong sense of three-dimensional immersion. According to the principles of optical imaging, if the image displayed on the third screen 52 (i.e., the second layer of image) includes images with lower brightness and images with higher brightness, then the lower brightness portion will be penetrated by the higher brightness portion of the first layer of image, that is, the lower brightness portion of the second layer of image will not be visible, thereby achieving the superposition of images in the same line of sight, producing a three-dimensional sense with front and back layers, and presenting an extremely unique three-dimensional immersive effect that blends virtual and real.

[0058] The following is Example 13 of the present invention. Based on Example 2, Figure 20 The first screen 3 (e.g., an LCD), the second screen 15 (e.g., an LCD), the first reflector 1, the second reflector 2, the third reflector 13, and the fourth reflector 14 are fixed via a support frame and perpendicular to a horizontal plane. The first tangent plane 16 and the second tangent plane 25 intersect at an angle α, and the third tangent plane 65 and the fourth tangent plane 66 intersect at an angle β. The values of angle α and β are 15°. The reflective surfaces of the second reflector 2 and the fourth reflector 14 are balanced and located in the same plane. That is, the third reflector 13 and the fourth reflector 14 can be combined into a single piece of flat coated transparent glass. The first tangent plane 16 and the second tangent plane 25 intersect at the first surround axis 9, and the third tangent plane 65 and the fourth tangent plane 66 intersect at the second surround axis 9. The reflective planes of the second reflector 2 and the fourth reflector 14 are in the same plane. Alternatively, the second reflector 2 and the fourth reflector 14 can be directly replaced with a single reflector. The four reflectors are all transparent flat coated glass. The corresponding reflective surfaces of the first reflector 1, the second reflector 2, the third reflector 13 and the fourth reflector 14 include metal films, which are used to enhance the reflection intensity of light.

[0059] Make the angle formed by the display surface of the first screen 3 and the first cutting plane 16 equal to the angle formed by the display surface of the first screen 3 and the second cutting plane 25; make the angle formed by the display surface of the second screen 15 and the third cutting plane 65 equal to the angle formed by the display surface of the second screen 15 and the fourth cutting plane 66, make the first screen 3 display the first parallax image or the reverse image of the first parallax image, make the second screen 15 display the second parallax image or the reverse image of the second parallax image, and the first parallax image and the second parallax image are two corresponding parallax images; in the virtual scene established by the 3D model, set the corresponding stereo cameras in the virtual scene to obtain the corresponding left and right eye parallax images, that is, the first stereo source image and the second stereo source image; alternatively, the left and right eye corresponding parallax images can be obtained by purchasing a binocular stereo camera to photograph the real scene. The positive virtual image refers to the image generated by the original image through specular reflection and having the same left and right direction as the original image; the reverse virtual image refers to the image generated by the original image through specular reflection and being symmetric to the original image. Points b and d are two points on the reflection surface of the first reflector 1, and among all the straight lines connecting any two points on the reflection surface of the first reflector 1, the distance of the line segment bd is the longest; points g and h are two points on the reflection surface of the third reflector 13, and among all the straight lines connecting any two points on the reflection surface of the third reflector 13, the distance of the line segment gh is the longest. The third line of sight 70 is a plane passing through the left eye 60 and point b, and the second line of sight 69 is a plane passing through the left eye and point d; the first line of sight 68 is a plane passing through the right eye and point g, and the fourth line of sight 71 is a plane passing through the right eye 61 and point f.

[0060] The first reflector 1 and the second reflector 2 are used to reflect the first screen 3 into corresponding virtual images at corresponding positions, and the third reflector 13 and the fourth reflector 14 are used to reflect the second screen 15 into corresponding virtual images at corresponding positions; that is, the first screen 3 generates the virtual images in the virtual image set A through the first reflector 1, the first screen 3 generates the virtual images in the virtual image set B through the second reflector 2, the second screen 15 generates the virtual images in the virtual image set C through the third reflector 13, and the second screen 15 generates the virtual images in the virtual image set D through the fourth reflector 14; the virtual image set A = {A1, A2, …, A n}, the virtual image set B = {B1, B2, …, B n}, the virtual image set C = {C1, C2, …, C n}, the virtual image set D = {D1, D2, …, D n}, where n is a natural number, 1 < n < 90, and n refers to the number of virtual images in the virtual image set A, the virtual image set B, the virtual image set C, and the virtual image set D. The virtual image An is the nth virtual image in the virtual image set A, the virtual image B n is the nth virtual image in the virtual image set B, the virtual image C n is the nth virtual image in the virtual image set C, the virtual image D n is the nth virtual image in the virtual image set D; the virtual image A n is the last virtual image generated in the virtual image set A, and the virtual image B n is the last virtual image generated in the virtual image set B. The virtual image C n is the last virtual image generated in the virtual image set C. The virtual image D n It is the last virtual image generated in the virtual image set D.

[0061] The first screen 3 and the second screen 15 are configured to simultaneously display corresponding left-eye and right-eye parallax images. Based on the principle of parallax stereoscopic imaging, within the third range 62, at least one virtual image in the virtual image set A is parallax-position-matched with at least one virtual image in the virtual image set C. For example, the parallax image of virtual image A5 (left-eye parallax image) is position-matched with the parallax image of virtual image C6 (right-eye parallax image); or the parallax image of virtual image C5 (right-eye parallax image) is position-matched with the parallax image of virtual image A6 (left-eye parallax image). Perform parallax position matching between at least one virtual image in the virtual image set A and at least one virtual image in the virtual image set C, set at least one virtual image in the virtual image set A as virtual image J, and set at least one virtual image in the virtual image set C as virtual image K. The virtual image J may include the virtual images in the virtual image set A within the third range 62, that is, virtual image A4 and / or virtual image A5 and / or virtual image A6 and / or virtual image A7; the virtual image K may include the virtual images in the virtual image set C within the third range 62, that is, virtual image C4 and / or virtual image C5 and / or virtual image C6 and / or virtual image C7.

[0062] The viewer's eyes are positioned close to the second reflector 2 and the fourth reflector 14 (the closer to the corresponding reflectors, the larger the range of the corresponding virtual image seen), and the left eye and the right eye are positioned on either side of the fourth plane 64 (the fourth plane 64 is the angle bisector of the angle V), and the fourth plane 64 is positioned as close as possible to the middle position between the two eyes, facing the first reflector 1 and the third reflector 13, to view the virtual image in front. When a viewer views the first reflector 1 and the third reflector 13 in a first direction 11, the left eye 60 can only see the virtual images in virtual image set A but not the virtual images in virtual image set B, while the right eye can only see the virtual images in virtual image set B but not the virtual images in virtual image set A. This means that the left eye 60 can see the virtual images corresponding to the third range 63 through the first reflector 1, such as A1, A2, A3, A4, A5, A6, and A7; while the right eye 61 can see the virtual images corresponding to the fourth range 67 through the third reflector 13, such as C1, C2, C3, C4, C5, and C6, C7. Based on the principle of parallax stereoscopic imaging, the viewer can simultaneously synthesize the virtual images A and B within the third range 62 to view the corresponding stereoscopic image. Therefore, the viewer can view a stereoscopic image with a stereoscopic effect through the reflectors 1 and 13. Virtual image A5 is configured to include the corresponding left-eye parallax image, and virtual image C6 is configured to include the corresponding right-eye parallax image. The eye then perceives a stereoscopic image (actually, a composite of the corresponding left-eye and right-eye parallax images) synthesized from virtual image A5 and virtual image C6. Since virtual image A5 is the reverse image of the first parallax image displayed on the first screen, and virtual image C6 is the forward image of the second parallax image displayed on the second screen, the first or second parallax image can be mirrored using video synthesis software and then displayed to produce a correctly synthesized stereoscopic image. Similarly, virtual image C5 is configured to include the corresponding right-eye parallax image, and virtual image A6 is configured to include the corresponding left-eye parallax image. Similarly, when a viewer views the second reflector 2 and the fourth reflector 14 in the second direction 32, the viewer can perceive a stereoscopic image through the second reflector 2 and the fourth reflector 14. In addition, an anti-peep film can be set on the display surface of the first screen 3 and the second screen 15. When viewing the virtual image set A, virtual image set B, virtual image set C and virtual image set D, the virtual image closer to the center of the line of sight has a higher brightness, forming a unique visual effect. The anti-peep film is a product that uses ultra-fine blinds optical technology to prevent images from being viewed from the side within a specific range.

[0063] The following is Example 14 of the present invention, based on Example 6 (see Figure 14), the reflector further includes a third reflector (13) and a fourth reflector (14), the third reflector (13) is the same as the first reflector (1), the fourth reflector (14) is the same as the second reflector (2), the third reflector (13) is symmetrically arranged with the first reflector (1), and the fourth reflector (14) is symmetrically arranged with the second reflector (2); according to embodiment 6, similarly, the second screen 15 can also be reflected into two groups of virtual images through the first reflector 1 and the second reflector 2 (curved mirror), namely: virtual image set {C1, C2, ..., C 12} and the virtual image set {D1,D2,…,D 12}, therefore, the virtual image set {C1, C2, ..., C 12} and the virtual image set {D1,D2,…,D 12 The image in the image can present an effect of magnifying the first screen 3 as a whole, and the virtual image can also form a surround effect.

[0064] The above description is only a preferred embodiment of the present invention. Those skilled in the art should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
