Abstract

This invention relates to techniques of displaying volumetric 3D images. Its principle is to project a set of 2D image frames, through the use of an image delivery mechanism, onto a fast moving screen. A new ""rotary reciprocating"" mechanism uses rotary motion to generate effective reciprocating effect, and hence can be used to move a screen. Image delivery mechanism has two types. The first type uses the ""rotary reciprocating"" mechanism to move a reflector set; the second type combines a varifocal mirror with a projection lens. Both types can keep the size and focus of projected images on the screen invariant while the screen is in motion. The ""rotary reciprocating"" mechanism can also be used to move a display panel directly, to create volumetric 3D images. This invention also includes new methods of projection to create images with colors and gray scale. It further includes new man-machine interface systems.

Description of the invention (I) Three-dimensional three-dimensional image display technology Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics Background of the invention From the perspective of users, the display technology currently used to display three-dimensional computer data can be divided into two Major categories: (1) perspective view method ································ 3D depth of field display technology: display a depth of field image on a 2D display, such as laser holography ) Or use the difference between the left and right eye angles and special glasses to generate the depth of field. The disadvantage of the perspective method is that it lacks a solid sense of depth. It is easy for users to use a mouse to locate on a two-dimensional plane. The vertical third dimension of the display screen) is extremely difficult. Therefore, various depth-of-field display technologies attempt to solve this shortcoming. However, computerized laser tomography requires huge computer power, and the technology is not yet mature: the left and right eye angle difference technology usually requires special glasses, which is uncomfortable Many people viewing in multiple directions. In addition, the viewing angle of all existing depth-of-field display technologies is extremely limited. It is a technology that can display three-dimensional three-dimensional images in space. The so-called volumetric three-dimensional image (volumetric 3D image) is a three-dimensional image that actually occupies the volume. Where it should be geometrically, the light emitted by each pixel hits almost all directions and is shaped in the eyes of the observer (please read the precautions on the back before filling this page) fOrder ——— #!

Description of the invention (2) The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed a real image. Therefore, observers can view this from almost any direction Three-dimensional three-dimensional images do not require any special glasses. Multiple observers can view the same three-dimensional image from different directions around the development space. Combining a projection device with a computer can be used to display three-dimensional computer data or images, and three-dimensional images 2 7 Animation. Applications include 3D medical imaging, stereo radar or sonar display 7K, and video game display Τρς device, etc. There are several types of known stereoscopic three-dimensional image display technology, the following overview of which is reviewed. The zoom mirror (Varifocal Mirror) technology is representative of early development. The zoom mirror system includes a fixed two-dimensional display, such as a cathode ray tube, and one side moves The user sees the virtual image of the two-dimensional display from the mirror. The periodic movement of the virtual image in the mirror forms a visualization space. A set of two-dimensional images are sequentially displayed on the two-dimensional display in sequence. The images are developed one by one at different positions in the development space one by one. Due to the effect of visual persistence, all the two-dimensional images displayed in the space form a three-dimensional three-dimensional image in the human eye. [See Traub 19 6 7] However, because it is a virtual image in the mirror, the viewing angle of this technology is very narrow. The second technology directly moves or rotates a two-dimensional display 'such as a circuit board filled with a light-emitting diode matrix, and then follows the circuit board. Move to different positions to 'control the light-emitting diode matrix graphics. Due to the visual persistence effect', all the light spots displayed in space form a three-dimensional three-dimensional image. in 19 7 3] The main disadvantage of this technology is that it is easy to cause reliability problems when moving or rotating an electronic display at high speed. Its resolution is also limited by the size of the light emitting diode and the paper is also suitable for China National Standards (CNS) A4 specifications (210X297 mm) (Please read the notes on the back before filling in this page) --- * Order #! 1222605 A7 B7 V. Description of the invention (3) Product. Then transfer the data from the computer or other instruments to the mobile There is also a problem with the signal interface on the display. Another technique uses one or more laser beams to scan a screen that moves or rotates at a high speed. The intersection of the laser beam and the screen is a fast and constantly moving space. light spot. Computer program control is used to control the scanning path of light spots in space, and the use of visual persistence effects can generate stereo 3D images. [Clifton 1993; Garcia 1989; Garcia and Williams 1991; Sol tan et al. 1998; Batchko 19 9 2 ] The disadvantage of this technology is that the complexity of the image is limited by the speed of the laser scanning technology. Industrial safety factors also limit the available laser luminosity. There is another technology that uses an electron beam to scan a mobile screen that is mined. Similar to a cathode ray tube with a moving screen. Another method is to use a crossed laser or electron beam to scan a luminous gas or solid that is sensitive to light or electricity [Rowe 1977; Downing et al. 1996; Korevaar I989]. The technology of using two laser beams with different pitch ratios to meet in a photosensitive gas or solid is referred to as the "principle of 2-step excitation" principle, because the first laser excites the photosensitive material At an intermediate energy level, the second laser excites the material to the second energy level, and the photoelectric effect at the second energy level then emits visible light. This type of "point scanning" technology has similar disadvantages to the aforementioned laser light point technology. Another type of technology discards the aforementioned "point scanning" method and adopts the "Chinese paper standard (CNS) A4 specification (21 °) for the entire paper size" (21〇 X29? Mm) (Please read the precautions on the back before filling out this page) -it »Printed by the Consumer Consumption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 1222605 A7 B7 V. Description of Invention (4) Screen" display method. The aforementioned earlier-developed zoom lens technology can be taken as an example. Another method is to stack a lot of transmissive flat-panel displays (such as liquid crystal displays) on top of each other to form a 7K display. [Hattori 199 2; ‘Sadovinik I " 8] However, since the flat display has a certain thickness and the amount that can be stacked in a certain space is limited, the image resolution of this method is also limited. Another method uses a screen that is curved into a vortex, as shown in Figure 1. When it rotates around the vortex 1Q1, the vortex screen 1Q2 can sweep through a display space 1. Then use a projector to project the two-dimensional images one by one onto the screen that swept the space [Montebello 1969]. However, the limitation makes the depth of focus of the projector limited, and the depth of the display space produced by this method is also limited. Another mechanism uses a screen twisted into a spiral, as shown in Figure 2 :. When it rotates around the axis 2 01, the spiral screen 2M can sweep through a display space 203. Then use a projector to project the two-dimensional images one by one onto the screen that sweeps through the space. To overcome the limitation of depth of focus, one method uses an * anamorphic lens to match the huge difference in depth of focus of a spiral screen [Morton 1990]. However, the manufacturing combination of an anamorphic lens is extremely complicated, and the imaging quality is not as good as that of a general projection lens. Another method is to project two-dimensional images one by one onto a mobile screen with parallel beams [Thompson I " 6]. Because the parallel beam is not limited by the depth of focus. However, to produce a parallel beam, laser light must be used as the light source, or Schierieri projection optical design must be used. Both of them have low energy efficiency, so the commercial cost is high. In order to overcome the shortcomings of the above various technologies, the inventor of this application has issued that this paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 '乂 297 mm) (Please read the precautions on the back before filling this page)- i'tv

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, 1T Summary of the Invention The present invention relates to a technology for generating a three-dimensional three-dimensional image, which is an improvement of "mobile screen projection technology". The basic principle of "Mobile Screen Projection Technology" is to use a "mechanical image transmission mechanism" of an optical mechanism to sequentially project a set of two-dimensional pictures on a fast-moving screen in order to project the image on the screen when the screen moves. The picture, its size and focus are not changed by the screen movement. The periodic movement of this screen in space forms a developing space. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1222605 Repair ^ '2: ^; ^ Change ^ weight A7 B7 V. Invention Explanation (厶) The projected two-dimensional images are developed one by one at different positions in the development space one by one. Due to the visual persistence effect, all the two-dimensional images developed in the space form one. Stereoscopic 3D image · Observers can view this stereoscopic 3D image from almost any direction without the need for any special glasses. The present invention describes a novel mobile screen mechanism called a "rotating reciprocating mechanism". The basic principle is to make the screen revolve around an axis. But it does not rotate; that is, the surface of the screen keeps facing a fixed direction during the revolution. In this way, the rotation of the screen can cover a cuboid display space, and the screen essentially moves back and forth in this space. There are many mechanisms that can produce "rotating reciprocating" motion. The main mechanism is to use a set of rotating arms to drive the screen. "Rotary reciprocating mechanism" can also be used to directly move a flat display, such as a circuit board filled with a light emitting diode matrix, or a polymer light emitting display (OLED) to generate a three-dimensional three-dimensional image . '' The present invention describes two new "image transmission mechanisms". The first uses a set of movable mirrors, the position of which is changed according to the screen position change to compensate for the change in the projection optical path, so the image picture projected on the screen 'Neither its size nor focus changes due to screen movement. The movement of the mirror uses the above-mentioned "rotary reciprocating mechanism". The second type uses a variable concave plano-convex mirror, whose focal length changes depending on the screen position.

Description of Invention (7) 92. Employee Consumption of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the cooperative, it has the function of a zoom lens, so the size and focus of the image screen projected on the screen can not be changed due to screen movement. In terms of displaying color or grayscale images, the present invention describes a novel color projection method. The basic principle is that the color pixel group is placed on the projection screen instead of the display panel, so the projector only needs to project a monochrome (white) light image. Monochrome 2D images are projected onto the screen before they appear in color. In addition, the use of extra pixels below the surface of the three-dimensional curved surface can increase the color or grayscale of the three-dimensional three-dimensional image of the object. The method is to decompose the data of the color surface to be displayed into the data of several sub-surfaces. Each subsurface has a different color, but the shape is similar to the original surface. Then in the development space, the surfaces are closely superimposed to reproduce the color of the original surface. The present invention also proposes two improved system man-machine interfaces to allow users to interact with stereoscopic 3D images in a more natural way.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs of the 1T 1222605 A7 B7 V. Description of the invention (彳) Figure 1S7K is intended to display a * cuboid in space, and only its six surfaces need to be displayed in pixels. Printed by the Intellectual Property Bureau, Ministry of Economic Affairs, Employee Consumer Cooperative, Detailed Description of the Invention First, the basic concepts of the "mobile screen projection technology" in a broad sense are outlined. As shown in Figure 3, the system consists of three main parts: (1) Mobile screen: image display screen (screen for short) 11 Zhou Sisheng movement to form a display space 12. There are basically two movement modes of the screen: Reciprocating or rotating. For example, a rectangular reciprocating screen can form a rectangular parallelepiped developing space, and a rotating type can form a cylindrical developing space. The screen is made of translucent material, so the projection screen can be seen on both sides of the screen. (2) Image transmission mechanism: The function of the image transmission mechanism 13 is to transmit the projection multi-beam 14 (the content of which is a set of two-dimensional image frames 14 a) from the projector to a mobile screen. When the screen is moved, it is projected. The size and focus of the image on the screen are not changed by the screen movement, and its orientation is kept in sync with the orientation of the screen. Arrow 17 indicates the projection direction of the projection beam onto the screen. (3): Image generation and projection device ( Projector for short): The projector 15 is used to generate one-dimensional two-dimensional images 14 ^ which form a three-dimensional three-dimensional image and project them on the screen 11. The projector is fixed in position and the two-dimensional images it projects Through much like the King and the movement of the transmission mechanism 13 to achieve synchronization screen. This paper size applies to China National Standard (CNS) A4C (210X297 mm) (Please read the precautions on the back before filling this page) 丨 Order 1222605 A7 B7 V. Description of Invention (ί) Staff of the Intellectual Property Bureau of the Ministry of Economic Affairs Consumption cooperatives print a set of two-dimensional pictures, such as the profile curve 14a of each section of a car body, through the image transmission mechanism, and sequentially project them on the mobile screen in order. Visualize sequentially at different locations in the imaging space 16. Due to the visual persistence effect, these two-dimensional images that are displayed in space form a three-dimensional three-dimensional image in the human eye. The observer can view this from almost any direction Stereoscopic 3D images' do not require any special glasses. Each of the above three main parts has various possible devices, so the system also has many possible combinations. There are many possible devices for moving the screen. For the convenience of description, the definition of reciprocating movement includes two-way reciprocating motion 'as well as periodic one-way scanning. For bidirectional back and forth motion, a ready-made example can use a sliding crank mechanism, as shown in Figure 4. The sliding crank mechanism needs a crank 411 through a connecting rod 412 and a sliding groove (or linear bearing) 413 to turn the rotary motion into a reciprocating motion, so it is relatively complicated. For periodic unidirectional sweeping, the examples shown in Figures 1 and 2 can be used. Swirl screens and spiral screens require a simple rotary motion to form a reciprocating mobile screen, but only a small area of the entire screen is available. This application proposes a novel moving screen mechanism, called a "rotary reciprocating mechanism". As shown in the figure, the basic principle is to take a flat screen 11 that revolves around an axis 5Q1, but does not rotate; that is, the surface of the screen keeps facing a fixed direction (z direction) during the revolution. In this way, the rotation of the screen can cover a cuboid display space I2 in the Z direction. If you observe the part where the screen intersects with this space, the screen is essentially in this space to 10 paper sizes.

1T 1222605 A7 B7 V. Description of the invention (II) The return motion is shown in the side view 5b-5d three continuous action diagrams. It is called r rotary reciprocating mechanism. " The advantage of this movement method is that the pure rotating mechanism generates substantial screen linear back and forth movement. The mechanism is simple and reliable, and projection; L 7 is also relatively tolerant and easy. Due to the movement of the screen, its full length must be greater than the width of the display space 12 in order to cover the projection beam in any position. There are naturally many mechanisms that can produce the above-mentioned "rotating reciprocation" motion. Figure 5a illustrates one of the device examples. The main mechanism is two pairs of synchronously rotating rotating arms SlOa-SIQd (pictured as disks in the figure). The two pairs of rotating arms can be mounted on a machine (the machine is not shown), and rotates around its axis 502 and 503, respectively. The screen 11 is fixed on a supporting structure 52. Both ends of the supporting structure are respectively mounted on a rod 522, and the rod is connected to two pairs of rotating arms via a rotating bearing 524. When the two pairs of rotating arms rotate around the central axes 502 and 503, the screen supporting structure and the screen rotate accordingly, and can move back and forth in a rectangular parallelepiped development space 12. Each swivel arm can be equipped with an appropriate counterweight 53 Q for smooth and smooth rotation balance. Figure 5f illustrates the mechanism that keeps the two pairs of rotating arms synchronized to rotate. A left and right timing belt and gear system synchronize the rotating arms (such as 510a and 510c) on the same side. The left and right sides are synchronized by a coaxial HQ. An electric motor 5 6 由此 can drive the whole mechanism coaxially. When using the "rotating reciprocating mechanism", the angle at which the screen is mounted on the screen supporting structure can be determined as needed. As shown in Figure 5 (a), the screen orientation is different from that shown in Figure 5a. Figure 6a-6c shows the device that uses the "rotary reciprocating mechanism" to move the screen. Fig. 6a is a sectional view of the mechanism, and Fig. 6b is a front view τκ.

Description of invention (丨 2) The main mechanism is a rotating arm 61Q. The swivel arm is mounted on a machine 6QQ and rotates around the central axis 6Q3. There is a timing belt gear 6Q5 on the bottom shaft. The bottom shaft and timing belt gears are fixed to the machine and do not rotate. One end of the rotating arm has a protruding shaft 61Q1, and a second timing belt gear 62ϋ on the shaft is rotatable. Two timing belt gears 6 2 0 and 6Q5 have the same diameter / number of teeth, and they are connected by a timing belt S3Q. The screen 11 and the supporting structure 621 are fixed on the second timing gear 6 2 0. In this way, when the rotating arm rotates, the second timing gear does not rotate, and the surface of the screen remains facing a fixed direction. As in Figures 5a and 5f, a balanced weight 5 3 0 can be placed on the other end of the rotating arm, and the movement of the rotating arm can be driven by a set of TF belts 64Q and a gear 61 0 2 fixed on the rotating arm. This device example may have another variant, that is, remove the timing belt 630 'and then add a * idle gear between the gear 6 0 5 and the gear 6 2 0 ^ g the shaft of the idler gear fft stands on the rotating arm, which Each of the teeth meshes with the gears 6 0 5 and 6 2 G to achieve the same function. "Rotary reciprocating mechanism" can also be used to directly move a flat display, such as a circuit board filled with a light emitting diode matrix, or a polymer light emitting display (OLED) to generate a three-dimensional three-dimensional image . As shown in the example shown in Figure 3, the flat display 2 01 is mounted on the supporting structure 5 2 Q, and then driven by two pairs of rotating arms, similar to the mechanism of Figure 5 at. As with the reciprocating screen, the full length of the flat display must be greater than the width of the display space 12. Each two-dimensional picture 16 constituting the three-dimensional three-dimensional image must be displayed at different positions on the flat-panel display, and moved to different positions corresponding to the flat-panel display. ) A4 size (210X297mm) (Please read the notes on the back before filling this page)

1222605 A7 B7 ----——----- V. Description of Invention (, 丨 3) The situation where the printed devices of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs went to different locations. If you want to use the "two-step energy level" principle to generate a three-dimensional three-dimensional image, you don't need a continuous screen. The screen power can be the intersection plane of a planar light beam and a light-sensitive material. The inclination of this plane beam can excite the photosensitive material to the intermediate energy level. The projection light of the projector must be the second screen aspect ratio to excite the material to the second energy level, and the visible light is emitted by the photoelectric effect of the second energy level. To make the ~ plane light beam sweep back and forth in a group of photosensitive materials, scanning mirrors and parabolic mirrors can be used. They are known to those skilled in optical mechanical technology and need not be described in detail. The image transmission mechanism can be divided into two categories. The first type is the moving mirror group. The principle is to place a mirror group into the light path of the projector to the mobile screen, and the reflex mirror group moves back and forth in synchronization with the screen, but its speed is one-half of the screen, so it compensates the projector to the mobile screen. The optical path changes, so that the size and focus of the image on the projection screen will not change due to screen movement. The figure shows an example described in [Tsao I " 9] U.S. Patent No. 5J54,414. The two-dimensional image produced by the projector display 15 01 is projected by the lens 15 02, reflected by the mirror group 13 () 1 and 13 () 2, and projected on the mobile screen 11. The display and the lens do not move. The mirrors 13Q1 and 1302 are at 90 degrees. The projection multi-light path 7 Q2 is parallel to the screen travel 7 Q1 direction. The screen travels back and forth between 11 and 11A, forming a cuboid display space12. The mirror group moves back and forth in synchronization with the screen, but its speed and travel are half of the screen, between 1301 to 13Q1A (and 13 () 2 to 13 () 2 ^). Therefore, the 13 paper sizes of the projector apply the Chinese National Standard (CNS) A4 specification (21 〇χ 297mm) ί ─ —See 丨 (Please read the precautions on the back before filling this page) Order-1222605 Please come to ^ Printed A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. The description of the invention (1+) The light path to the screen remains unchanged ◦ Using the above-mentioned image transmission mechanism, the entire picture can be continuously projected on the screen Come up to generate a three-dimensional three-dimensional image. Fig. 7b shows a second example of the device. This device uses only one side of the moving mirror 1300, and the incident angle of the projected light beam to the moving mirror plus the reflection angle forms an angle ', so the two sides of the development space are parallelograms12. For another angle, the optical path difference caused by the movement of the mirror will be slightly larger than twice the stroke of the mirror. Therefore, for the best effect, the mirror stroke should be reduced as needed. The figure shows the third example of the device. This device uses a fixed set of total reflection prisms 13 0 3 to reduce the incident angle and reflection angle of the projection beam 7 Q 2 to the moving mirror, so the imaging space can be closer to a cuboid. Figure 7'd shows the fourth example of the device. This device uses a polarizing beam splitter 130 7 to reduce the incident angle and reflection angle of the projected beam onto the moving mirror to degrees, so the imaging space can be Into a rectangular parallelepiped. In this device, the projection light beam entering the polarized beam splitter is preferably polarized. For example, the image of a display generally based on liquid crystal is polarized. In this case, a quarter wave iretarder IMS must be used between the polarizing, spectroscopic, and moving mirrors. The polarization axis of the projection beam should be selected so that the projection light enters the polarized beam splitter 稜鏡 and is reflected to the moving mirror 13⑼. The axial direction of the quarter wave retarder should also be selected. After the projected light passes through the quarter wave retarder twice, the axis of the polarized light turns 90 degrees, which can reach the screen through the polarized beam splitter. The movement of the moving mirror group can adopt a mechanism similar to the screen movement, for example, a sliding crank mechanism similar to FIG. 4 or a “rotating reciprocating 14” similar to FIG. 5a. The paper size is applicable to the Chinese National Standard (CNS) Λ4 specification (21 〇x—297 mm) ^ (Please read the notes on the back before filling this page)

1222605 A7 B7 V. Description of the invention (5) Mechanism ", the construction method can change the screen and supporting structure in the above mechanism to an appropriate reflector group and supporting structure. For example, when the mirror group is a right-angle double mirror (used in Figure 7a), the "reciprocating reciprocating mechanism" device can be placed on the support structure 52Q as shown in Figure 8. The synchronization and coordination between the movement of the mirror group and the screen movement can naturally be achieved by various mechanisms, such as using gears or timing belts. This is known to those skilled in mechanical technology and need not be described in detail. However, when the "rotary reciprocating mechanism" is used for both the mirror group movement and the screen movement, the "rotary reciprocating mechanism" of the two can be combined and simplified. Figures 93 and 91 :) show a case where the mobile mirror 130 0 and the mobile screen 11 are mounted on the same group of rotating arms. Figure M is a schematic sectional view, and Figure 9b is a schematic front view. Figure 9c shows the mechanism turning to the highest point, and Figure 9d shows the mechanism turning to the lowest point. The swivel arms 91Qa and 91QC are similar to the swivel arm in FIG. 5a, but there is an extension structure on it: a short axis 912 is included, and an extension arm 914 on the short axis extends to the axis of the swivel axis 901. There is a short shaft hit 6 and the above are all fixed to the rotating arm body. The short shaft 912 is connected to both ends of the screen supporting structure 520 via a bearing (not shown). The radius from the minor axis 912 to the axis 901 is R, so when the rotary arm rotates, the screen reciprocating stroke is 2R, as shown in Figs. 9C and 9d. The extension arm short axis 916 is connected to both ends of the support structure 92 G by bearings (not shown). Structure 9 2 0 is similar to structure 5 2 0, except that a reflector 1300 is mounted thereon. The radius of the extension arm short axis 916 to the axis 9Q1 is 1/2 R ′. Therefore, when the rotating arm rotates, the reciprocating stroke of the mirror is R, as shown in FIG. 9 c and FIG. In short, using the extension structure can make—the group of rotating arms have two different motion strokes at the same time, one for moving the screen and one for 15 (please read the precautions on the back before filling this page)-Order 4 '· · National Standard (CNS) A4 (210X297 mm) 1222605 A7 B7 V. Description of the invention (β) Used to move the mirror to achieve the effect of optical path compensation. For example, 9 0 2 shows a usable multi-path for projection, this path is similar to FIG. 7b. • m In the installation method shown in Figure 7 and 7c, because the incident angle of the projected beam to the moving mirror is greater than Q degrees, the two faces of the development space are parallelograms instead of regular rectangles. This is because the mirror surface is flat when the mirror moves back and forth. If the mirror surface is rotated while the mirror is reciprocating, the position of the projection picture on the screen can be changed, that is, the 'shape of the development space can be corrected to make it closer to a rectangular parallelepiped. Figure 10a shows the situation of the device method in Figure 7b. After the reflector moves from the lowest point 13QQA to the highest point, it turns slightly counterclockwise to make the reflected projection path 彳 to 7Q3 and the projection path at the lowest point. 7 Q 3A is no longer parallel, so the shape of the development space can be corrected. The required turning angle of the mirror depends on the actual system optical path. For example, in Figure IQa, if the angle between the highest point projection path 703 and the most striking point path 70 "is t ', the mirror needs to be turned from the lowest point to the most local point. 1/2 t. As for the method of rotating the mirror, naturally there are many mechanisms available. Figure 10b shows the method of rotating the mirror when using the "reciprocating reciprocating mechanism", that is, using two sets of rotating arms with different rotation radii, one set at The front lQlOa, a set of rear 1Q1QC. Due to the different radius of rotation of the front and rear rotating arms, the distance between the front axis 1021 and the rear axis 1Q22 will change significantly when the mirror support structure 102ϋ moves. For example, a small chute 1Q24 is used. The second type of image transmission mechanism is a zoom light component group. The basic principle is to use a light component group that can quickly change the focal length to adjust the projector to project a two-dimensional image. National Standards (CNS) Α4 grid (210X297 mm) (Please read the notes on the back before filling out this page) ": Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Consumer Cooperatives 1222605 A7 B7 V. Invention Ming (i?) Imaging distance and magnification to match the distance of the screen. This type of image transmission mechanism and the image projection part of the projector has become an indistinguishable one. Figure 11 illustrates [Tsao I " 9] United States The example described in Patent No. 5,954,414 mainly uses a zoom lens 11Q1, which can project the two-dimensional image produced by the multiviewer display 1501 onto a screen that moves near and far, and maintain the magnification constant. The actual device can be counted値 The controller 11Q3 controls the brake 1102 of the zoom lens according to the screen distance data transmitted from the sensor 110.

In addition to zoom lenses, other zoom light components can also be used or used in conjunction with fixed-focus projection lenses. The second example of the zoom light element is the zoom mirror (Varifocal Mirror) mentioned in the background section of the invention. A zoom mirror is a thin film mirror whose mirror curvature can be quickly changed to a flat, concave, or convex mirror. The detailed structure can be found in [Rawson I969]. Fig. 12a illustrates the optical function of the zoom lens in geometrical optics. When the mirror surface is plane 12, an object 9 located at 0 becomes a virtual image 9f at CV, 0M = 0. When the mirror becomes convex 12Q3X, Fx is the focal point of the convex mirror. The object 9 becomes a virtual image & X, OM > XM, the image height is less than the object height. When the mirror becomes concave UWv, Fv is the focal point of the concave mirror, object 9 The virtual image is 9v at V, 0M < VM, the image height is greater than the object height. From the above, it can be seen that changing the mirror curvature of the zoom lens can simultaneously change the imaging distance 隹 and the size, and both are related. Using this function, the zoom lens can Used in combination with a fixed focal length lens to achieve the effect of a zoom lens. One of the unintended installation methods in Figure 12b is to place the zoom lens 12 Q 3 into the light path of the display panel 15 Q1 to the projection lens 15 02. Because the zoom lens is reflective It is necessary to use a total reflection chirp to arrange the optical path. Under this arrangement, the curvature of the zoom lens is controlled. 17 This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read first Note on the back, please fill out this page again)-Order shame. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, printed 1222605 A7 B7 V. Invention Description uf) You can control the optical path length from the display panel to the projection lens. The size of the projection lens. Therefore, when the zoom lens becomes convex, the display panel becomes smaller and closer to the projection lens. The projection image becomes farther away, such as position B. When the zoom lens becomes concave, the display panel becomes larger and further away from the projection lens, and the projection image It is closer, such as position A. At this time, the imaging magnification also becomes smaller, but because the display panel becomes larger, the imaging size can still be the same as position B. All the optical path and optical parameters can be calculated by geometric optics Need to elaborate. Figure 12c The second method of the device is mainly to place the zoom lens 12Q3 into the optical path of the projection lens to the mobile screen 11. In this arrangement, because the projection lens is also affected by the zoom lens, use a The brake 12QQ is used to adjust the distance from the display panel 15 01 to the projection lens to increase a controllable variable. In a broad sense, any zoom plano-convex mirror can achieve the above functions, and is not necessarily limited to the original structure of the zoom lens. 7 Image generating device In principle, it can include any image display device, such as: projection cathode ray tube and projection liquid crystal display, etc. The image projection device includes a projection lens and light Source, or other image projection devices such as laser and laser beam scanning devices. If you want to make full use of the characteristics of "whole screen projection" to generate complex three-dimensional images, the image generation device must have a high frame reproduction rate (frame refresh rate) and allow high brightness. There are several image generating devices that meet the above requirements, including light emitting diodes, ferroelectric liquid crystal (FLC) display 71 [see Clark 1981], digital micromirror display ( digital micr〇 ~ mirror device / DMD for short) [Ref. Mignardi 1994], and film 18 This paper size is applicable to China National Standard (CNS) A4 (210X: 297 mm) (Please read the precautions on the back first to save Fill in this page) tr—Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 1222605 Α7 Β7 V. Description of the invention) Micro-mirror display [thin-film micromirror array / referred to as TMA] [See Kim and Hwang 1999], etc. 0 • The above images are produced The device, except for the light-emitting diode and laser, has no color on the display itself. To produce color images, there are two types of methods according to the general display technology. The first is to use three display panels, such as three LCD panels, each of which is cast with different colors of light (such as the three primary colors of red, green, and blue), and then the three different color screen projections are superimposed together. Another method is to use a display panel with color triads. For example, a color liquid crystal display is often stacked on a colorless liquid crystal panel with one or more thin films with a small color filter array to produce colors. The two methods are known to those skilled in display technology and need not be described in detail. However, the process of making color pixel groups on the LCD panel is complicated. To achieve the purpose of generating a three-dimensional three-dimensional image by projection, the present invention proposes a novel color projection method. The basic principle is that the color pixel group is placed on the projection screen instead of the display panel, so the projector only needs to project a monochrome (white) light image. Monochrome two-dimensional scenes are projected onto the screen before they appear in color. As shown in FIG. 14, the screen 1411 can be a translucent material 1452, or a layer of thin film 1451 with a color filter array (shown as repeated red, green, blue, and blue stripes) on the mine or pasted. The image projected by the projector is composed of white light spots 14 6 0. White light spots fall on red stripes to become red light spots 146 QR; white light spots fall on green or blue stripes to become green or blue light spots, that is, P46OG or 146〇B. Another way to make a screen is to use a translucent material with colored pixel group patterns as the screen. The most important thing in this method is that the white light image projected by the projector must be aligned with the correct color pixel group. This paper size is applicable to the Chinese National Standard (CNS) Α4 specification (male thin)-(Please read the precautions on the back first (Fill in this page again) " τ, 1T Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1222605 V. Description of Invention (20) The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed A7 B7 can reconstruct the correct color picture on the screen. Although in the "Mobile Screen Projection Technology", the screen is constantly moved, but its operation is cyclically heavy. Therefore, the relative position of the screen and the projector is known at any time. In this way, the relative position of the projection position of the projector on the screen and the color pixel group pattern is also known. As long as you grasp this relative position, you can properly arrange the projected white light image content, align the correct color pixel group, and reconstruct the correct color picture on the screen. Using the characteristics of the three-dimensional three-dimensional image, a new method can be used to combine pixels in the development space to produce more color or grayscale. According to our experimental observations, three-dimensional three-dimensional images are most suitable for expressing the spatial distribution relationships of three basic geometric forms: sparse sets of points, curves (including straight lines), and curved surfaces (including planes). In many cases, three-dimensional objects can be displayed using curved surfaces. Because to display a three-dimensional object in space, you only need to express the surface of the object with pixels, and you don't need to worry about its interior. For example, Fig. 15 shows a rectangular parallelepiped in space. It only needs to display its six surfaces in pixels (three surfaces 151-! · 53 are drawn in the figure), and the internal pixels are not used. This ^ characteristic is not available in the two-tenon display. This is a trait that allows us to use the extra pixels below the surface of the object to increase the color or grayscale of the surface of the object. The method is to decompose the data of yesterday's colorful tunes into the data of the transition and secondary surface. Each subsurface has a different color, but the shape is similar to the original surface. Then in the development space, the surfaces are closely superimposed to reproduce the color of the original surface. This method is particularly suitable for displays using color pixel groups. As shown in Figure 16, a three-dimensional curved surface data 21 and its surface 20 are shown on the left. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page)

Description of the invention (2 丨) ¥ ^ iL.f Whether the contents of $$ are infused into # 正-mentioned by the Ministry of Economic Affairs Intellectual Property Bureau employee consumer cooperative printed a part of the data points 2 2. Plane 20 represents the position where the screen is moved at an instant, and the intersection surface with the three-dimensional curved surface is the picture that should be projected at that time. 23 is an enlarged view of a small part of the intersection surface. The four small square points 24-27 on the surface represent the surface of the curved surface, and W represents white. The right side of Figure 16 shows how to display the color of the original three-dimensional surface with a subsurface in the development space. First, the data of the color surface is decomposed into three subsurfaces, as shown in 162R, 162G, and 162B, which are respectively red, green and blue. Then in the development space, the subsurfaces are closely superimposed 162. 163 is an enlarged view of the image projected on the screen at a certain moment, and its position corresponds to 23. The pixels 162B-1, 162B-2, and 162B-3 are all part of the sub-surface 162B, and the other pixels are part of the sub-surfaces 162R and 162G. The colors of the three subsurfaces are mixed to reproduce the colors of the original surface. For example, pixels 162R-1 (red), 162G-1 (green), and 162B-1 (blue) are mixed into white, that is, the color corresponding to the original data point 24. R G B in the small squares in the figure respectively represent the two colors of red, green and blue. The above-mentioned sub-curved surface display method, although increasing the thickness of the curved surface, has a small negative impact on the visual effect of the three-dimensional three-dimensional image. First, the added pixels are on the inside of the surface of the object. Secondly, in most cases, the observer ’s line of sight is close to the direction of the superposition of the subsurface, and the superposition thickness is less significant at this perspective. If only grayscale is required, each surface can be white or other monochromatic, and no color pixel group is required for the display panel or screen. The pixel density distribution of each surface also varies from place to place, so after superimposition, it can show that the grayscale distribution is different everywhere. 21 This paper size applies to China National Standard (CNS) A4 (210X297 mm) (Please read the precautions on the back before filling this page) -i-τί

The above method using a sub-surface to display the surface color or grayscale is a basic method for displaying three-dimensional three-dimensional images, so it can be applied to any The three-dimensional three-dimensional image display device is not limited to the hardware technology described in this application. If the image generating device uses three display panels with color pixel groups and overlaps the three color images, naturally more colors can be obtained. The 3D 3D image display can improve the system's human machine interface through additional devices, allowing users to interact with the 3D 3D image in a more natural way. One of the ideal ways to interact is to allow users to reach into the imaging space with their hands or handheld devices, directly point, touch, and process 3D images.

According to the principle of optical imaging, the three-dimensional three-dimensional image in the development space will become a real image, floating in the air 185Q close to the optical axis of the concave mirror. This real image is also three-dimensional and three-dimensional, and it looks like it is jumping out of the concave mirror.

The system shown in Fig. 18 above is a method for communicating the world in the display space of the three-dimensional three-dimensional display with the external world.

In addition, two other points should be specified 'to highlight the nature of the above system. First, the three-dimensional image displayed on the two-dimensional display by the perspective method cannot effectively use the above-mentioned system, because the image does not occupy real space. Second, the relationship between a general computer mouse and its cursor is not the same as the relationship between the physical part and the virtual part of the aforementioned hand tool.
