Description

Technical Field

[0001] This invention relates to a levitation stereoscopic display device, and more particularly to a levitation stereoscopic display device that includes a reflection module and projects a levitation stereoscopic image. Background Technology

[0002] With the evolution of display technology, its applications and development directions are becoming increasingly diversified. For example, current automotive surround view systems utilize multi-lens image stitching technology, combined with 2D display devices, to present the image on the dashboard. However, image stitching surround view systems cannot perfectly display the surroundings of the vehicle, creating blind spots (such as the front corner of the bumper, the rear corner of the taillights, etc.). Furthermore, 2D displays lack depth information, requiring drivers to rely on their subjective judgment of distance and depth when reversing or cornering, often leading to collisions. In addition, the 2D display screen on the dashboard is relatively far from the user, requiring them to stand up and approach to view and interact with it, failing to provide a good viewing and interactive experience.

[0003] Stereoscopic imaging can solve the problem that planar images cannot present depth of field. However, in application scenarios with limited space, especially when the user is close to the camera, existing technologies struggle to simultaneously achieve stereoscopic imaging, environmental detection, and provide a viewing and interactive experience. Summary of the Invention

[0004] This invention provides a floating stereoscopic display device that uses a reflection module to reflect a floating stereoscopic image into a stereoscopic imaging space. It can also be combined with an environmental detector to detect environmental and user information. For example, it can present objects or obstacles around a vehicle in stereoscopic form, allowing the driver to judge the distance between the vehicle and surrounding obstacles to reduce the occurrence of accidents. It can also be combined with a motion detector to detect the user's movements. Combined with the depth-of-field display feature of the floating stereoscopic display device, the distance between the interactive display plane and the user can be adjusted to improve the user experience. It can provide a viewing and interactive operation experience and expand the application scope of the technology.

[0115] Please refer to Figure 1 According to an embodiment of the present invention, a floating stereoscopic display device 100 is disclosed. The floating stereoscopic display device 100 includes a floating display module 110 and a reflection module 160. The floating display module 110 includes a processor 120. The processor 120 generates stereoscopic image data 140 in response to input image data 130 and provides the stereoscopic image data 140 to the floating display module 110. The type of input image data will be determined by... Figure 2A , Figure 3A , Figures 4 to 6A and Figure 7A The illustrated embodiments are described in detail. Specifically, input image data can be detected by a detector, including but not limited to environmental, human, static, and dynamic images, and then a 3D model can be generated in virtual space, providing information such as angle, size, and distance. This model is then processed by a processor to obtain corresponding stereoscopic image data. The processor can generate stereoscopic image data by performing calculations on the ground or in the cloud using built-in apps, software, and algorithms. However, the present invention is not limited to this, and other methods of generating stereoscopic image data are also applicable. The floating stereoscopic display device of the present invention can be one or more, and each device can have one or more floating display modules, processors, and other components. One or more processors can be used as needed to provide one or more sets of stereoscopic image data or instructions to one or more floating stereoscopic display devices.

[0116] like Figure 1As shown, the floating display module 110 projects a floating stereoscopic image 151 based on the stereoscopic image data 140. In such a way... Figure 1 In the illustrated embodiment, the floating display module 110 includes a light field display 111 and a reflective projection component 112. Light projected from the light field display 111 onto the reflective module 160 via the reflective projection component 112 converges to form a floating stereoscopic image 151. In some embodiments, the reflective projection component may be a Dihedral Corner Reflector Array (DCRA). A DCRA is a passive optical component that can project a complete mirror image of an image onto another side. Specifically, the light field display is responsible for generating a high-quality 3D stereoscopic image at the near end, and then the DCRA projects the 3D image to the far end, providing the user with an immersive floating display effect. However, the invention is not limited to this; any component that can mirror-project light projected by the light field display 111 onto the reflective module 160 is applicable. In some embodiments, the visible range of the floating display module 110 is determined by the reflective projection component 112. For example, when the reflective projection component is a DCRA (Distributed Direct Reflective Aspect Ratio), it consists of two sets of multiple reflective layers (e.g., glass) oriented perpendicularly to each other. When the thickness of the reflective layer is 1.5 mm, its field of view (FOV) is approximately ±20 degrees; when the thickness of the reflective layer is 1.25 mm, its FOV is approximately ±25 degrees. In other words, the field of view can be controlled by controlling the thickness of the reflective layer.

[0117] like Figure 1 As shown, the reflection module 160 reflects the floating stereoscopic image 151 into the stereoscopic imaging space 170, forming a reflected floating stereoscopic image 150. In... Figure 1 In the illustrated embodiment, the stereoscopic imaging space 170 is located in front of the user 195. However, the invention is not limited to this; the position of the stereoscopic imaging space and the corresponding reflection module configuration can be designed according to requirements. In some embodiments, the reflection module is movable. Details regarding the movable reflection module, the stereoscopic imaging space, and the reflected floating stereoscopic image will be discussed later. Figures 7A to 7E The illustrated embodiments are described in detail. Figure 1As shown, the light field display 111 emits light through a projection light path Ie according to the stereoscopic image data 140 provided by the processor 120. The light is then projected onto the reflection module 160 via the reflection projection component 112 and converged to form a floating stereoscopic image 151. The number of light paths is only for illustration. Specifically, the light field display 111 of the present invention can separate the imaging focus from the surface of the light field display 111. In response to the stereoscopic image data 140, it simulates the light emission effect of a real object through light field reconstruction technology. For example, it can simulate that the light emission point of the projection light path Ie is located behind the light field display 111, so that the floating stereoscopic image 151 has depth information and provides a light field image with a realistic stereoscopic feel. By simulating the effect of the light source of a real object originating from behind the screen, the optical path can be extended through optical path design, thereby increasing the distance at which the reflected floating stereoscopic image 150 is projected to the user's eyes. This design architecture can also be called a negative light field display. However, the present invention is not limited thereto. Due to the characteristic that the light field display 111 can separate the imaging focus from the surface of the light field display 111, it can also focus on the front of the light field display 111.

[0118] like Figure 1 As shown, the reflection module 160 reflects the floating stereoscopic image 151 into the stereoscopic imaging space 170 via the reflected light path Ir, forming a reflected floating stereoscopic image 150. The number of light paths is only for illustration. The reflection module of the present invention can be the windshield of a moving vehicle or the reflector of a game console; however, the present invention is not limited to these, and any component that can reflect a floating stereoscopic image into the stereoscopic imaging space is applicable. Specifically, the light field display of the present invention projects an image generated based on stereoscopic image data provided by the processor, which has the characteristics of left-right reversal and front-back displacement. Through the reflection of the reflection module, a reflected floating stereoscopic image with the same image direction as the input image data source (e.g., environmental image or user image) can be formed. In some embodiments, the reflected floating stereoscopic image may include text messages, such as interactive messages, speed warnings, license plate numbers, etc. In some embodiments, the surface of the reflection module has curvature, and the stereoscopic image data content provided by the processor can be pre-compensated so that the floating stereoscopic image projected by the floating display module is distortion-free. Compared to the virtual images of previous technologies, which are prone to causing eye fatigue, the floating stereoscopic real images projected by this invention provide a practical solution, especially in situations requiring prolonged viewing, such as driving or interactive games, which can significantly reduce the burden on users.

[0119] Please refer to Figures 2A to 2C According to an embodiment of the present invention, a floating stereoscopic display device 200 is disclosed. The floating stereoscopic display device 200 includes a floating display module 210 and a reflection module 260. The floating stereoscopic display device 200 is substantially similar to... Figure 1The levitation stereoscopic display device 100, wherein similar component symbols indicate similar components, and for the sake of brevity, related descriptions are omitted here, and the previously described levitation stereoscopic display device and its related details are applicable here.

[0120] like Figure 2A As shown, the floating display module 210 includes a processor 220. The processor 220 generates stereoscopic image data 240 in response to input image data 230 and provides the stereoscopic image data 240 to the floating display module 210. The floating display module 210 projects a floating stereoscopic image 251 based on the stereoscopic image data 240. The reflection module 260 reflects the floating stereoscopic image 251 into the stereoscopic imaging space 270, forming a reflected floating stereoscopic image 250. Figures 2A to 2C In the illustrated embodiment, the holographic display device 200 can be applied to a mobile vehicle 205 (e.g., an automobile), where the windshield 265 reflects the holographic image 251 into a stereoscopic imaging space 270, forming a reflected holographic image 250, wherein the stereoscopic imaging space 270 is located in front of the user 295 of the mobile vehicle 205. In some embodiments, when the mobile vehicle includes multiple users, the reflected holographic image can be deflected to any one or more positions of the driver or passengers by adding or adjusting the reflection module or adjusting the holographic display module.

[0121] like Figure 2A As shown, the holographic display device 200 further includes an image detector 280 that detects environmental images 282 of the scene 281 and provides input image data 230 to the processor 220 in response to the environmental images 282. The image detector 280 can be a camera, radar, light source, infrared, or acoustic detector, etc. Figure 2A In the illustrated embodiment, the mobile vehicle 205 has eight cameras 280a; however, the invention is not limited to this, and the type and number of image detectors can be adjusted as needed. Specifically, the image detectors 280 (e.g., cameras 280a) detect environmental images 282 around the mobile vehicle 205 and provide input image data 230 to the processor 220 in response to the environmental images 282. The processor 220 generates stereoscopic image data 240 in response to the input image data 230 and provides the stereoscopic image data 240 to the levitation display module 210. The levitation display module 210 projects a levitation stereoscopic image 251 based on the stereoscopic image data 240. A reflection module 260 (e.g., windshield 265) reflects the levitation stereoscopic image 251 into the stereoscopic imaging space 270, forming a reflected levitation stereoscopic image 250, wherein the reflected levitation stereoscopic image 250 is a real-time levitation stereoscopic image in response to the environmental images 282. Figure 2A and Figure 2BIn the illustrated embodiment, the floating display module 210 includes a light field display 211 and a reflective projection component 212, and the light projected from the light field display 211 to the reflective module 260 through the reflective projection component 212 converges to form a floating three-dimensional real image 251. Figure 2A As shown, the light field display 211 emits light through the projection light path Ie according to the stereoscopic image data 240 provided by the processor 220. The light is then projected through the reflection projection component 212 to the reflection module 260 and converged to form a floating stereoscopic real image 251. The reflection module 260 reflects the floating stereoscopic real image 251 into the stereoscopic imaging space 270 through the reflection light path Ir to form a reflected floating stereoscopic real image 250. The number of light paths is only for illustration.

[0122] Figure 2B For the corresponding Figure 2A A partially enlarged schematic diagram of the floating stereoscopic display device 200. (See attached diagram.) Figure 2B As shown, the light field display 211 emits light through the first projection light path Ie1, the second projection light path Ie2, and the third projection light path Ie3 according to the stereoscopic image data 240 provided by the processor 220. The light is then projected onto the reflection module 260 via the reflection projection component 212 and converged to form a floating stereoscopic real image 251. The reflection module 260 reflects the floating stereoscopic real image 251 into the stereoscopic imaging space 270 through the first reflection light path Ir1, the second reflection light path Ir2, and the third reflection light path Ie3, respectively, to form a reflected floating stereoscopic real image 250. The number of light paths is only for illustration. Specifically, the first projection light path Ie1 is the leftmost light that can be projected by the floating display module 210, the second projection light path Ie2 is the middle light that can be projected by the floating display module 210, and the third projection light path Ie3 is the rightmost light that can be projected by the floating display module 210. The three light paths converge on one side relative to the reflective projection component 212 to form a floating stereoscopic real image 251. Through reflection by the reflective module 260, the first reflection light path Ir1, the second reflection light path Ir2, and the third reflection light path Ir3, respectively corresponding to the first projection light path Ie1, the second projection light path Ie2, and the third projection light path Ie3, converge again in the stereoscopic imaging space 270 to form a reflected floating stereoscopic real image 250. Figure 2A and 2B In the illustrated embodiment, the reflective module 260 can be a windshield 265. For example... Figure 2B As shown, the angle between the two largest projection light paths of the floating display module 210 is the light emission angle α of the floating display module 210, such as the angle between the first projection light path Ie1 and the third projection light path Ie3. In some embodiments, the light emission angle of the light field display 211 should be consistent with the light emission angle of the corresponding reflective projection component 212 to avoid ghosting.

(Example) Figure 2C As shown, the reflected levitation stereoscopic image 250 may include triangular cones in the environment surrounding the moving vehicle 205. However, the invention is not limited to this. Stationary objects (e.g., obstacles) or moving objects (e.g., pedestrians or vehicles) in the environment can be detected by an image detector to provide input image data to the processor to generate a 3D model in virtual space, and then obtain corresponding stereoscopic image data to project the reflected levitation stereoscopic image 250 in response to the environmental image onto the user 295. Specifically, the reflection module 260 (e.g., windshield 265) projects the levitation stereoscopic image (e.g., Figure 2A or Figure 2B The floating stereoscopic image 251 shown is reflected in the stereoscopic imaging space 270, forming a reflected floating stereoscopic image 250, wherein the stereoscopic imaging space 270 is located in front of the user 295 of the moving vehicle 205. In this way, when the driver (e.g., user 295) is reversing or turning, if an object is too close to the vehicle, the floating stereoscopic display device 200 can provide a real-time stereoscopic environment modeling display, allowing the driver to better judge the distance and avoid over-reliance on the driver's subjective judgment, which could lead to collision accidents.

[0124] Please refer to Figure 3A , 3B and Figure 3D According to an embodiment of the present invention, a floating stereoscopic display device 300 is disclosed. The floating stereoscopic display device 300 includes a floating display module 310 and a reflection module 360. The floating stereoscopic display device 300 is substantially similar to... Figure 2A The 200 is a levitation stereoscopic display device, wherein similar component symbols indicate similar components, and for the sake of brevity, related descriptions are omitted here, and the previously described levitation stereoscopic display device and its related details are applicable here.

[0125] like Figure 3A As shown, the floating display module 310 includes a processor 320. The processor 320 generates stereoscopic image data 340 in response to input image data and provides the stereoscopic image data 340 to the floating display module 310. The floating display module 310 projects a floating stereoscopic real image 351a or a floating stereoscopic real image 351b based on the stereoscopic image data 340. The reflection module 360 ​​reflects the floating stereoscopic real image 351a or the floating stereoscopic real image 351b into the stereoscopic imaging space 370, forming a reflected floating stereoscopic real image 350a or a reflected floating stereoscopic real image 350b.

[0126] like Figure 3A As shown, the holographic display device 300 further includes an image detector 380. The image detector 380 is substantially similar to... Figure 2AThe image detector 280, as described above, and its related details are applicable here. The image detector of the present invention, in addition to being able to... Figures 2A to 2C In addition to detecting environmental images, the image detector 380 can also detect the user's position 383a or 383b within scene 381 and provide position data 331 to the processor 320 in response to the user's position 383a or 383b. The processor 320 adjusts the position of the reflected floating stereoscopic image (e.g., 350a or 350b) in the stereoscopic imaging space 370 in response to the position data 331. Specifically, the optimal projection imaging position may differ depending on the user's position. By detecting the position of the user 395, the image detector 380 can adjust the position of the reflected floating stereoscopic image (e.g., 350a or 350b) in the stereoscopic imaging space 370 accordingly. For example, when the user 395 is at position 383a, the optimal projection imaging position is at the reflected floating stereoscopic image 350a; while when the user 395 is at position 383b, the optimal projection imaging position is at the reflected floating stereoscopic image 350b. Specifically, the holographic display device 300 has a depth-of-field range D, within which clear imaging is possible. For example, in this embodiment, within the depth-of-field range D, the imaging position closest to the reflection module 360 ​​is the position of the reflected holographic image 350a, and the imaging position furthest from the reflection module 360 ​​is the position of the reflected holographic image 350b. The reflected holographic image can be adjusted within the depth-of-field range D; for example, its position can be adjusted between the positions of the reflected holographic image 350a and 350b. However, the invention is not limited thereto, and those skilled in the art will understand the meaning of the depth-of-field range D. The holographic image and the reflected holographic image can be adjusted by the processor through built-in Apps, software, and algorithms, either locally or in the cloud.

Figure 3A As shown, the light field display 311 emits light through the projection light path Ie according to the stereoscopic image data 340 provided by the processor 320. The light is then projected through the reflection projection component 312 to the reflection module 360 ​​and converged to form a floating stereoscopic real image 351a or a floating stereoscopic real image 351b. The reflection module 360 ​​reflects the floating stereoscopic real image 351a or the floating stereoscopic real image 351b into the stereoscopic imaging space 370 through the reflection light path Ir, forming a reflected floating stereoscopic real image 350a or a reflected floating stereoscopic real image 350b. The number of light paths is only for illustration.

The light is projected through the reflective projection component 312 to the reflective module 360 ​​and converged to form a floating stereoscopic real image 351a or a floating stereoscopic real image 351b. The reflective module 360 ​​reflects the floating stereoscopic real image 351a or the floating stereoscopic real image 351b into the stereoscopic imaging space 370 using the first reflection light path Ir1, the second reflection light path Ir2, and the third reflection light path Ir3, respectively, corresponding to the first projection light path Ie1, the second projection light path Ie2, and the third projection light path Ie3, to form a reflected floating stereoscopic real image 350a or a reflected floating stereoscopic real image 350b. The number of light paths is for illustrative purposes only. Figure 3B As shown, the angle between the two largest light paths that the floating display module 310 can project is the light emission angle α of the floating display module 310, such as the angle between the first projection light path Ie1 and the third projection light path Ie3.

For example, the holographic display device 300 can be configured for a central control panel display or dashboard to provide real-time stereoscopic environment modeling display, allowing the driver (e.g., user 395) to better judge distances, and can adjust the position of the reflected holographic image in the stereoscopic imaging space according to the driver's position (e.g., the driver's seat position, the driver's visual focus, etc.), avoiding image blurring caused by user position movement (e.g., seat movement or driver's visual focus movement).

[0132] Please refer to Figure 5 According to an embodiment of the present invention, a floating stereoscopic display device 500 is disclosed. The floating stereoscopic display device 500 includes a floating display module 510 and a reflection module 560. The floating stereoscopic display device 500 is substantially similar to... Figure 2A The 200 is a levitation stereoscopic display device, wherein similar component symbols indicate similar components, and for the sake of brevity, related descriptions are omitted here, and the previously described levitation stereoscopic display device and its related details are applicable here.

[0133] like Figure 5As shown, the floating display module 510 includes a processor 520. The processor 520 generates stereoscopic image data 540 in response to input image data and provides the stereoscopic image data 540 to the floating display module 510. The floating display module 510 projects either a floating stereoscopic real image 551a or a floating stereoscopic real image 551b based on the stereoscopic image data 540. The reflection module 560 reflects either the floating stereoscopic real image 551a or the floating stereoscopic real image 551b into the stereoscopic imaging space 570, forming a reflected floating stereoscopic real image 550a or a reflected floating stereoscopic real image 550b.

[0134] like Figure 5 As shown, the holographic display device 500 further includes a motion detector 590 that detects the action 596 of the user 595 and provides motion data 532 to the processor 520 in response to the action 596. The processor 520 adjusts the reflected holographic image (e.g., reflected holographic image 550a or reflected holographic image 550b) in response to the motion data 532. Specifically, the processor 520 provides correspondingly adjusted stereoscopic image data 540 to the holographic display module 510. The holographic display module 510 projects the holographic image 551a or holographic image 551b based on the stereoscopic image data 540. The reflection module 560 reflects the holographic image 551a or holographic image 551b into the stereoscopic imaging space 570, forming the reflected holographic image 550a or reflected holographic image 550b. The motion detector 590 can be a camera, radar, light source, infrared, or acoustic detector, etc. Figure 5 In the illustrated embodiment, motion detector 590 can be a gesture recognition device, and action 596 is gesture 593; motion detector 590 can also be an eye-tracking device, and action 596 is gaze position 594. However, the invention is not limited to this, and the type and number of motion detectors can be adjusted as needed. For example, in some embodiments, a gyroscope or accelerometer can be used to infer the action and position of user 595. Figures 7A to 7E The embodiments shown are described in detail.

[0135] Specifically, user 595 can use actions, gestures, and gaze positions (such as user 595's visual focus) to have the motion detector 590 detect user 595's actions and 596 adjust the reflected holographic image accordingly (for example, adjusting the position of the holographic image between the positions of reflected holographic image 550a and reflected holographic image 550b). Figure 5In the illustrated embodiment, user 595 can use action 596 (gesture 593 or gaze position 594) to move the reflected levitation stereoscopic image 550a, which is close to the imaging position of the reflection module 560, to a reflected levitation stereoscopic image 550b at another imaging position, moving away from the reflection module 560. However, the present invention is not limited to this.

[0136] In such Figure 5 In the illustrated embodiment, the floating display module 510 includes a light field display 511 and a reflective projection component 512, and the light projected from the light field display 511 to the reflective module 560 through the reflective projection component 512 converges to form a floating stereoscopic real image 551a or a floating stereoscopic real image 551b. Figure 5 As shown, the light field display 511 emits light through the projection light path Ie according to the stereoscopic image data 540 provided by the processor 520. This light is projected via the reflective projection component 512 to the reflective module 560, where it converges to form a floating stereoscopic image 551a or 551b. The reflective module 560 reflects the floating stereoscopic image 551a or 551b into the stereoscopic imaging space 570 through the reflective light path Ir, forming a reflected floating stereoscopic image 550a or 550b. The number of light paths is for illustrative purposes only. By incorporating a motion detector, this invention provides a viewing and interactive experience, expanding the application scope of the technology. Figure 5 The holographic display device 500 shown can be applied to mobile vehicles (such as automobiles), and the previously described mobile vehicles and related details are applicable here. For example, the holographic display device 500 can be used to adjust the reflected holographic image. For instance, a passenger in the front seat can use gestures to bring the reflected holographic image closer to themselves, enjoying a readily accessible operating experience without getting up. They can also operate the magnified reflected holographic image to confirm the distance to obstacles or determine parking space, etc. By adjusting the distance between the interactive display plane and the user, the user experience is improved, solving the problem in the prior art where the front-end 2D display screen is too far from the user, requiring them to get up and approach to view and interact with it. In some embodiments, in addition to the previously described image detector and motion detector, the reflected holographic image can also be adjusted in response to any electronic signals such as audio, GPS, acceleration / deceleration, steering, door opening / closing, or vehicle operation. For example, it can simultaneously display vehicle speed and overspeed warnings, vehicle turn signals, or gear information, or magnify and remind users of relevant lane information when exiting a ramp.

[0137] Please refer to Figures 6A to 6CAccording to an embodiment of the present invention, a floating stereoscopic display device 600 is disclosed. The floating stereoscopic display device 600 includes a floating display module 610 and a reflection module 660. The floating stereoscopic display device 600 is substantially similar to... Figure 2A The 200 is a levitation stereoscopic display device, wherein similar component symbols indicate similar components, and for the sake of brevity, related descriptions are omitted here, and the previously described levitation stereoscopic display device and its related details are applicable here.

[0138] like Figure 6A As shown, the floating display module 610 includes a processor 620. The processor 620 generates stereoscopic image data 640 in response to input image data 630 and provides the stereoscopic image data 640 to the floating display module 610.

[0139] like Figure 6A As shown, the holographic display device 600 further includes an image detector 680. The image detector 680 is substantially similar to... Figure 4 Image detector 480, the previously described image detector and its related details are applicable here. Image detector 680 can detect user image 684 located within scene 681 and provide input image data 630 to processor 620 in response to user image 684. Figure 6A As shown, the holographic display device 600 further includes a second image detector 686, which detects a second user image 688 located within a second scene 687, and provides input image data 630 to the processor 620 in response to the second user image 688, wherein the second scene 687 is different from scene 681. The processor 620 generates stereoscopic image data 640 in response to the input image data 630, and provides the stereoscopic image data 640 to the holographic display module 610. The holographic display module 610 projects a holographic stereoscopic image 651 based on the stereoscopic image data 640. The reflection module 660 reflects the holographic stereoscopic image 651 into the stereoscopic imaging space 670, forming a reflected holographic stereoscopic image 650. The second image detector 686 is substantially similar to... Figure 4 The image detector 480, as previously described, and its related details, are applicable here. Figure 6A and Figure 6B In the illustrated embodiment, the floating display module 610 includes a light field display 611 and a reflective projection component 612, and the light projected from the light field display 611 to the reflective module 660 through the reflective projection component 612 converges to form a floating three-dimensional real image 651. For example... Figure 6AAs shown, the light field display 611 emits light through the projection light path Ie according to the stereoscopic image data 640 provided by the processor 620. The light is then projected through the reflection projection component 612 to the reflection module 660 and converged to form a floating stereoscopic real image 651. The reflection module 660 reflects the floating stereoscopic real image 651 into the stereoscopic imaging space 670 through the reflection light path Ir to form a reflected floating stereoscopic real image 650. The number of light paths is only for illustration.

[0140] Figure 6B For the corresponding Figure 6A A partially enlarged schematic diagram of the 600 floating stereoscopic display device. (See attached diagram.) Figure 6B As shown, the light field display 611 emits light through a first projection light path Ie1, a second projection light path Ie2, and a third projection light path Ie3 according to the stereoscopic image data 640 provided by the processor 620. This light is projected via the reflective projection component 612 to the reflective module 660, where it converges to form a floating stereoscopic image 651. The reflective module 660 reflects the floating stereoscopic image 651 into the stereoscopic imaging space 670 through a first reflection light path Ir1, a second reflection light path Ir2, and a third reflection light path Ir3, respectively, corresponding to the first projection light path Ie1, the second projection light path Ie2, and the third projection light path Ie3, thus forming a reflected floating stereoscopic image 650. The number of light paths is for illustrative purposes only. Figure 6B As shown, the angle between the two largest light paths that the floating display module 610 can project is the light emission angle α of the floating display module 610, such as the angle between the first projection light path Ie1 and the third projection light path Ie3. The previously described projection light path, reflection light path, light emission angle and related details are applicable here.

[0141] Figure 6C For the corresponding Figure 6A A schematic diagram illustrating the usage scenario of the 600 floating stereoscopic display device. In, for example... Figure 6C In the illustrated embodiment, the levitation stereoscopic display device 600 can be applied to a mobile vehicle 605 (e.g., a car), and the reflection module 660 (e.g., a windshield 665) projects the levitation stereoscopic image (e.g., a real image). Figure 6A or Figure 6B The floating stereoscopic image 651 shown is reflected in the stereoscopic imaging space 670, forming a reflected floating stereoscopic image 650, wherein the stereoscopic imaging space 670 is located in front of the user 695 of the moving vehicle 605. Figure 6AIn the illustrated embodiment, image detector 680 can detect user image 684 of user 695 located within mobile vehicle 605, and provide input image data 630 to processor 620 in response to user image 684; second image detector 686 can detect second user image 688 of second user 697 located within second mobile vehicle 606, and provide input image data 630 to processor 620 in response to second user image 688, wherein the second mobile vehicle 606 is different from mobile vehicle 605, and the reflected levitation stereoscopic image 650 is a real-time levitation stereoscopic image in response to the second user image 688. Figure 6A In the embodiment shown, the second mobile vehicle 606 is provided with a second image detector 686 and a second processor 620r, and the second processor 620r provides input image data 630 to the processor 620 in response to the second user image 688.

[0142] For example, when two vehicles (e.g., mobile vehicle 605 and second mobile vehicle 606) are equipped with holographic display devices, in addition to sensing the environment outside the vehicle and sensing the user's position, movements (eye movements, gestures), or images inside the vehicle, as mentioned above, information transmission and image projection between the two vehicles can also be achieved. For example, the input image data 630 provided by the near-end vehicle system (e.g., processor 620) in response to the user image 684 can be processed by the near-end vehicle system (e.g., mobile vehicle 605), and the first input image data 630n provided by the response to the user image 684 can also be transmitted to the far-end vehicle system (e.g., second processor 620r); conversely, the second input image data 630r provided by the far-end vehicle (e.g., second mobile vehicle 606) in response to the second user image 688 can also be transmitted to the near-end vehicle system (e.g., processor 620) through the far-end vehicle system (e.g., second processor 620r). These image data can be transmitted via Wi-Fi or Bluetooth, but the present invention is not limited thereto. In the above scenario, the processor can combine input image data from different signal sources (e.g., remote environmental or user image information and near-end environmental or user information) to generate stereoscopic image data, thus creating a hybrid far-end and near-end reflected floating stereoscopic real image. For example, a video call connected by an in-vehicle system can achieve real-time stereoscopic image communication through a floating stereoscopic display device, and can also simultaneously project the surrounding environment to maintain driving safety. It can be used to simultaneously project near-end or far-end user images and / or environmental images, expanding the application methods of this invention.

[0143] Please refer to Figures 7A to 7B According to an embodiment of the present invention, a floating stereoscopic display device 700 is disclosed. The floating stereoscopic display device 700 includes a floating display module 710 and a reflection module 760. The floating stereoscopic display device 700 is substantially similar to... Figure 5The levitation stereoscopic display device 500, wherein similar component symbols indicate similar components, and for the sake of brevity, related descriptions are omitted here, and the previously described levitation stereoscopic display device and its related details are applicable here.

[0144] like Figure 7A As shown, the floating display module 710 includes a processor 720. The processor 720 generates stereoscopic image data 740 in response to input image data and provides the stereoscopic image data 740 to the floating display module 710. The floating display module 710 projects a floating stereoscopic image 751 based on the stereoscopic image data 740. The reflection module 760 reflects the floating stereoscopic image 751 into the stereoscopic imaging space 770, forming a reflected floating stereoscopic image 750.

[0145] like Figure 7A and Figure 7B As shown, the holographic display device 700 (or the host 701 of the gaming device 705) further includes a motion detector 790, which detects the actions 796 of the user 795 and provides motion data 732 to the processor 720 in response to the actions 796. The processor 720 adjusts the reflected holographic image 750 accordingly in response to the motion data 732. The previously described motion detector and its related details are applicable here. Specifically, the user 795 can adjust the reflected holographic image 750 by detecting the user 795's actions 796 through movements, gestures, gaze positions, etc., via the motion detector 790. Figure 7A In the example shown, user 795 can adjust the reflected floating stereoscopic image 750 by action 796 (gesture 793 or gaze position 794). Figure 7B For the corresponding Figure 7A A schematic diagram illustrating the usage scenarios of the 700 floating stereoscopic display device, in situations such as... Figure 7B In the illustrated embodiment, the holographic display device 700 can be applied to a gaming device 705 (e.g., an immersive gaming console including a host 701). The host 701 includes a reflector 765 that reflects the holographic image 751 into a stereoscopic imaging space 770, forming a reflected holographic image 750. The stereoscopic imaging space 770 is located in front of the user 795 of the gaming device 705. Because the stereoscopic imaging space 770 of the holographic display device 700 has a depth space (range), clear imaging is possible within this depth range, allowing the reflected holographic image 750 in the stereoscopic imaging space 770 to have a depth effect. This provides both a sense of depth and distance when projecting game images, resulting in a more immersive experience, such as in fishing games.

[0146] In such Figure 7A and Figure 7BIn the illustrated embodiment, the floating display module 710 includes a light field display 711 and a reflective projection component 712, and the light projected from the light field display 711 to the reflective module 760 through the reflective projection component 712 converges to form a floating three-dimensional real image 751. Figure 7A and Figure 7B As shown, the light field display 711 emits light through the projection light path Ie according to the stereoscopic image data 740 provided by the processor 720. The light is then projected to the reflection module 760 via the reflection projection component 712 and converged to form a floating stereoscopic real image 751. The reflection module 760 reflects the floating stereoscopic real image 751 into the stereoscopic imaging space 770 through the reflection light path Ir, forming a reflected floating stereoscopic real image 750. The number of light paths is only for illustration.

[0147] In such Figures 7A to 7E In the illustrated embodiment, the reflection module 760 (e.g., reflector 765) adjusts accordingly in response to motion data 732, and moves the stereoscopic imaging space 770 and the reflected floating stereoscopic image 750 accordingly. For example, the fish in the reflected floating stereoscopic image 750 can swim in the air, providing a realistic sense of depth. By rotating or moving the reflection module 760, the player (e.g., user 795) can move and fish simultaneously, enhancing the gaming experience. Figure 7B As shown, the host 701 further includes a motion detector 790, which can be installed in the handheld device 791 of the host 701 (e.g., a fishing net or fishing gun device). The motion detector 790 includes, for example, a gesture recognition device, an eye-tracking device, a gyroscope, an accelerometer, or a light detector, which can be used to infer the actions and position of the user 795 and provide motion data 732 to the processor 720 to adjust the reflected levitation stereoscopic image 750 accordingly. The reflection module 760 responds to the motion data 732 and adjusts accordingly, and moves the stereoscopic imaging space 770 and the reflected levitation stereoscopic image 750 accordingly, which can change the position of the displayed image. Figure 7B As shown, a reflective levitation stereoscopic image 755 can also be generated based on the actions of the user 795. For example, after pulling the trigger of the fishing gun, the user 795's actions are detected by the handheld device 791 (for example, the light detector of the motion detector 790 is used to detect the aiming position of the fishing gun), and the motion data 732 is provided to the processor 720 to form a reflective levitation stereoscopic image 755 of the action of shooting the fishing net. For ease of explanation and neatness of the diagram, the reflective levitation stereoscopic image 755 is only shown in the stereoscopic imaging space 770.

[0148] Figures 7C to 7E For the corresponding Figure 7A The diagram shows the reflection module 760 at different angles. Specifically, the holographic display device 700 has a movable reflection module 760, whose stereoscopic imaging space 770 and reflected holographic image 750 can move with different angles of the reflection module 760. Figure 7C In the top view shown, the angle θ between the reflection module 760 and the reference plane 761 is 30 degrees, which can be understood as the reflection module 760 being rotated 30 degrees to the left. These values ​​are only examples and are not intended to be limiting; the direction and angle range can be adjusted according to the projection requirements. The light field display 711 emits light through the projection light path Ie according to the stereoscopic image data 740 provided by the processor 720. This light is projected onto the reflection module 760 via the reflection projection component 712 and converges to form a floating stereoscopic image 751. The reflection module 760 reflects the floating stereoscopic image 751 into the stereoscopic imaging space 770 through the reflection light path Ir, forming a reflected floating stereoscopic image 750. The number of light paths is for illustrative purposes only.

[0149] like Figure 7D In the top view shown, the angle θ between the reflection module 760 and the reference plane 761 is 0 degrees, which can be understood as the reflection module 760 being in a horizontal state. These values ​​are only examples and are not intended to be limiting; the direction and angle range can be adjusted according to the projection requirements. The light field display 711 emits light through the projection light path Ie according to the stereoscopic image data 740 provided by the processor 720. The light is projected onto the reflection module 760 via the reflection projection component 712 and converges to form a floating stereoscopic image 751. The reflection module 760 reflects the floating stereoscopic image 751 into the stereoscopic imaging space 770 through the reflection light path Ir, forming a reflected floating stereoscopic image 750. The number of light paths is for illustrative purposes only.

[0150] like Figure 7E In the top view shown, the angle θ between the reflection module 760 and the reference plane 761 is -30 degrees, which can be understood as the reflection module 760 rotating 30 degrees to the right. These values ​​are only examples and are not intended to be limiting; the direction and angle range can be adjusted according to the projection requirements. The light field display 711 emits light through the projection light path Ie according to the stereoscopic image data 740 provided by the processor 720. The light is projected onto the reflection module 760 via the reflection projection component 712 and converges to form a floating stereoscopic image 751. The reflection module 760 reflects the floating stereoscopic image 751 into the stereoscopic imaging space 770 through the reflection light path Ir, forming a reflected floating stereoscopic image 750. The number of light paths is for illustrative purposes only.

[0151] By comparison Figures 7C to 7EThe holographic display device 700 has a movable reflective module 760, whose holographic imaging space 770 and reflected holographic image 750 can move with different angles of the reflective module 760. However, the invention is not limited to this. The reflective module can change the position, size, shape, etc. of the reflected holographic image by moving, rotating, or changing curvature in response to environmental data or motion data. For example, in a scenario with multiple users, it may be difficult to manufacture a reflective projection component with a viewing range covering all users due to technological limitations. The invention can also achieve the effect of interactive projection for multiple users by adjusting the reflective module. In summary, the motion detection of the holographic display device provided by the present invention can include motion detection of physical devices (e.g., operating game devices) and motion detection of non-physical devices interacting with the reflected holographic image (e.g., adjusting position, size, distance, clicking).
