[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0026] To provide a better understanding of the present invention, the three-dimensional holographic projection system will first be described.

[0027] The 3D holographic projection system employs an upright or inverted pyramid structure, composed of four trapezoidal glass panels. It operates on the principle of Pepper's ghost technology (holography based on Pepper's ghost technology is also known as pseudo-holography). Compared to 3D holographic display technology based on beam interference, Pepper's ghost technology is characterized by its simpler principle, lower cost, ease of implementation, ability to observe 3D objects with the naked eye, and high fidelity.

[0028] The principle of a 3D holographic projection system is to project an image from a display screen onto a projection glass at a 45° angle using light reflection, creating a reflected virtual image. Holographic projection systems employing Pepper's Ghost technology typically display objects with brighter light and dimmer ambient light for better display effects. It should be noted that the projection glass is semi-reflective.

[0029] Specifically, the working process of a 3D holographic projection system can be as follows: The object to be displayed is placed in the center of spatial coordinates; four cameras capture images of the object horizontally from four directions; by adding lighting and adjusting the position and angle of the light sources, basic 3D display can be achieved, such as... Figure 1A The diagram shows the display area and screen layout. The object to be displayed is a mountain peak, and the display is a large square area, which includes four smaller square display areas. Each smaller square display area shows the image of the mountain peak, and the blank area in the large square area is the background.

[0030] according to Figure 1A It can be seen that there is a lot of waste in the existing technology of displays.

[0031] Example 1

[0032] Figure 1B This is a flowchart of a screen display method provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation where a display in a three-dimensional holographic projection system displays an image to be displayed. The method can be executed by a screen display device, which can be implemented in software and / or hardware and can be configured in an electronic device that carries screen display function.

[0033] See Figure 1B The screen display method shown includes:

[0034] S110. Based on the vertical projection of each projection glass in the 3D holographic projection system onto the display, determine the local display area corresponding to each projection glass.

[0035] The display can be used to show an image to be displayed. The projection glass can be used to display the image to be displayed on the display to the user. A partial display area refers to at least a portion of the display area of ​​the display. This embodiment of the invention does not limit the shape and / or number of partial display areas, which can be set by a technician based on experience or needs. For example, if the projection glass is trapezoidal in shape and there are four projection glasses, then the display contains four trapezoidal partial display areas.

[0036] Specifically, based on the vertical projection of each projection glass in the 3D holographic projection system onto the display, the display is divided into local display areas corresponding to each projection glass.

[0037] S120. Adjust the size of the image to be displayed from the camera corresponding to the local display area so that the image to be displayed occupies a larger area of ​​the corresponding local display area.

[0038] The camera can be used to provide a data stream, i.e., the image to be displayed, for the holographic projection system. This embodiment of the invention does not specifically limit the type of camera; it can be set by a technician based on experience. Optionally, the camera can be a real camera or a virtual camera. It should be noted that the number of cameras is the same as the number of local display areas.

[0039] Here, the image to be displayed refers to the image of the object that needs to be displayed.

[0040] Specifically, adjust the size of the image to be displayed by the camera corresponding to the local display area so that the image to be displayed occupies a larger area in the corresponding local display area.

[0041] This invention provides a screen display solution that determines the local display area corresponding to each projection glass in a 3D holographic projection system based on the vertical projection of each projection glass onto a display screen. The size of the image to be displayed from the camera corresponding to the local display area is adjusted so that the image to be displayed occupies a larger area of ​​the corresponding local display area. This solution, by determining the local display area based on the projection glass, ensures that the local display area occupies the maximum area on the display screen, avoiding wasted space. Furthermore, by ensuring that the image to be displayed occupies a larger area of ​​the corresponding local display area, the utilization rate of the local display area is improved, thereby increasing the overall utilization rate of the display screen.

[0042] Based on the above embodiments, when there are at least two local display areas, in order to avoid the images to be displayed in the at least two local display areas being overlaid, the background of the camera corresponding to the local display area can be set to not fill.

[0043] Understandably, setting the background of the camera corresponding to the local display area to not fill can prevent the images to be displayed in different local display areas from overlapping, so that the images to be displayed in the local display area can be displayed completely.

[0044] Example 2

[0045] Figure 2A This is a flowchart of a screen display method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further refines the operation of "adjusting the size of the image to be displayed by the camera corresponding to the local display area so that the image to be displayed occupies a larger area of ​​the corresponding local display area" into "adjusting the rectangular parameters of the camera corresponding to the local display area to update the image to be displayed; adjusting the focal length of the image displayed by the corresponding camera so that the image to be displayed occupies a larger area of ​​the corresponding local display area," thereby improving the mechanism for determining the size of the image to be displayed. It should be noted that for parts not described in detail in this embodiment, please refer to the descriptions in other embodiments.

[0046] See Figure 2A The screen display method shown includes:

[0047] S210. Based on the vertical projection of each projection glass in the three-dimensional holographic projection system onto the display, determine the local display area corresponding to each projection glass.

[0048] S220. Adjust the rectangular parameters of the camera corresponding to the local display area to update the image to be displayed.

[0049] The rectangle parameter can be used to determine the size of the camera. Specifically, the rectangle parameter can include the rectangle length and the rectangle width.

[0050] In an optional embodiment, adjusting the rectangular parameters of the camera corresponding to the local display area includes: for each local display area, adjusting the rectangular parameters of the camera corresponding to the local display area based on the distance from the center point of the display to the local display area and the maximum side length of the local display area parallel to the edge of the display.

[0051] Specifically, for any local display area, the distance from the center point of the display to that local display area is taken as the width of the rectangle; the longest side of that local display area that is parallel to the edge of the display is taken as the length of the rectangle.

[0052] Understandably, by introducing the center point of the display and the maximum side length, the rectangular parameters are determined, which avoids the problem of the displayed image being too small when the camera's field of view is small, thus increasing the camera's field of view.

[0053] This invention does not limit the number of projection glass panes or the shape of the display; these can be set by technicians based on experience or needs. In one optional embodiment, the rectangular parameters of the camera can be determined based on the number of projection glass panes and the shape of the display. Specifically, if there are four projection glass panes and the display is square, adjusting the rectangular parameters of the camera corresponding to the local display area includes: adjusting the rectangular parameters of the camera corresponding to the local display area based on the screen length of the display.

[0054] In this embodiment of the invention, when the display is square, since the screen length of the display is uniform, the rectangular parameters of the camera corresponding to the local display area can be directly adjusted according to the screen length of the display. Optionally, the rectangle length in the rectangular parameters of the camera corresponding to the local display area can be set to the screen length of the display.

[0055] Alternatively, the rectangle width in the rectangle parameter of the camera corresponding to the local display area can be set to half the screen length of the monitor; or, the rectangle width in the rectangle parameter of the camera corresponding to the local display area can be set to the height of the local display area.

[0056] Understandably, by determining the rectangle length based on the monitor's screen length, and the rectangle width based on half the monitor's screen length or the height of a partial display area, the efficiency of determining the rectangle parameters is improved, and the amount of computation is reduced.

[0057] In this embodiment of the invention, by limiting the number of projection glass and the shape of the display, a simpler method is provided for a special three-dimensional holographic projection system to determine the rectangular parameters of the camera. This avoids the waste of resources that occurs when determining the rectangular parameters of the camera using a uniform method, and reduces the amount of computation.

[0058] S230. Adjust the focal length of the image displayed by the corresponding camera so that the image to be displayed occupies a larger area of ​​the corresponding local display area.

[0059] Optionally, the size of the image to be displayed can be adjusted by changing the focal length, so that the image occupies a larger area of ​​the corresponding local display area. If the image to be displayed is too large, the focal length of the corresponding camera's display image can be reduced to shrink the image; if the image to be displayed is too small, the focal length of the corresponding camera's display image can be increased to enlarge the image.

[0060] Alternatively, the camera lens can be zoomed in or out to make the image occupy a larger area of ​​the corresponding local display area. If the image to be displayed is too large, the camera lens can be zoomed out to shrink the image; if the image to be displayed is too small, the camera lens can be zoomed in to enlarge the image.

[0061] For example, the display result after adjusting the focus can be seen in [reference needed]. Figure 2B The diagram shows the display area and screen layout. The object to be displayed is a mountain peak; there are four trapezoidal projection screens; the monitor is square; the monitor includes four trapezoidal partial display areas; each partial display area displays one image to be displayed.

[0062] It should be noted that the larger area can be the area of ​​the largest inscribed graphic within the local display area. This embodiment of the invention does not impose any limitation on the shape of the largest inscribed graphic; it can be set by a technician based on experience. For example, the largest inscribed graphic can be one of the largest inscribed circle or the largest inscribed rectangle, etc.

[0063] This invention provides a screen display solution. The operation of adjusting the size of the image to be displayed by the camera corresponding to a local display area, so that the image occupies a larger area of ​​the corresponding local display area, is refined into adjusting the rectangular parameters of the camera corresponding to the local display area to update the image to be displayed; and adjusting the focal length of the image displayed by the corresponding camera, so that the image to be displayed occupies a larger area of ​​the corresponding local display area. This solution, by introducing rectangular parameters and focal length, maximizes the area of ​​the image to be displayed in the local display area, avoids wasting the local display area, and improves the utilization rate of the local display area.

[0064] Based on the above embodiments, this invention also provides a slide turner. The slide turner is connected to a computer for communication, and its customizable functions allow for switching of displayed results. For example, the operation keys on the front of the slide turner can be set to navigate up and down pages, and the two buttons on the side can be set to pause and resume. This invention does not specifically limit the communication connection method; it can be configured by a technician based on experience or needs. For example, the communication connection between the slide turner and the computer can be via Bluetooth.

[0065] For example, the process of switching display results using a slide turner is as follows: In the Update function, the keyboard event is obtained, and the Boolean value of Input.GetKeyDown(KeyCode.DownArrow)[input keyboard key code (key code.down arrow key)] is used to determine whether the "down" button on the keyboard is pressed, and then the specific key content is executed.

[0066] In this embodiment of the invention, a slide turner is used instead of a computer keyboard in the prior art to switch the display results, which is simple to operate and has a low cost.

[0067] Example 3

[0068] Figure 3 This is a schematic diagram of a screen display device provided in Embodiment 3 of the present invention. This embodiment can be applied to the situation where a display in a three-dimensional holographic projection system displays an image to be displayed. The method can be executed by a screen display device, which can be implemented in software and / or hardware and can be configured in an electronic device that carries screen display function.

[0069] like Figure 3 As shown, the device includes: a partial display area determination module 310 and a to-be-displayed image adjustment module 320. Wherein,

[0070] The local display area determination module 310 is used to determine the local display area corresponding to each projection glass based on the vertical projection of each projection glass on the display in the three-dimensional holographic projection system.

[0071] The image to be displayed adjustment module 320 is used to adjust the size of the image to be displayed from the camera corresponding to the local display area, so that the image to be displayed occupies a larger area of ​​the corresponding local display area.

[0072] This invention provides a screen display solution that uses a local display area determination module to determine the local display area corresponding to each projection glass in a 3D holographic projection system based on the vertical projection of each projection glass onto the display. A display image adjustment module then adjusts the size of the image to be displayed from the camera corresponding to the local display area, ensuring that the image occupies a larger area within the respective local display area. This solution, by determining the local display area based on the projection glass, maximizes the area occupied by the local display area, avoiding wasted space. Furthermore, by ensuring the image occupies a larger area within the corresponding local display area, it improves the utilization rate of the local display area, thereby increasing the overall utilization rate of the display.

[0073] Optionally, the partial display area determination module 310 includes:

[0074] The image to be displayed update unit is used to adjust the rectangular parameters of the camera corresponding to the local display area in order to update the image to be displayed;

[0075] The focus adjustment unit is used to adjust the focus of the image displayed by the corresponding camera so that the image to be displayed occupies a larger area of ​​the corresponding local display area.

[0076] Optionally, the image update unit to be displayed is specifically used for:

[0077] For each local display area, the rectangular parameters of the camera corresponding to that local display area are adjusted based on the distance from the center point of the display to that local display area and the maximum side length of the local display area that is parallel to the edge of the display.

[0078] Optionally, if the number of projection glass is four and the display is square, the image update unit to be displayed includes:

[0079] The rectangular parameter adjustment subunit is used to adjust the rectangular parameters of the camera corresponding to the local display area according to the screen length of the monitor.

[0080] Optional, rectangular parameter adjustment sub-unit, specifically used for:

[0081] Set the rectangle length in the rectangle parameter of the camera corresponding to the local display area to the screen length of the monitor.

[0082] Optional, rectangular parameter adjustment sub-unit, specifically used for:

[0083] Set the rectangle width in the rectangle parameters corresponding to the camera for the partial display area to half the screen length of the monitor; or,

[0084] Set the rectangle width in the rectangle parameters of the camera corresponding to the local display area to the height of the local display area.

[0085] Optionally, the device may also include:

[0086] The No-Fill module is used to set the background of the camera corresponding to a local display area to be non-filled.

[0087] The screen display device provided in the embodiments of the present invention can execute the screen display method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects for executing each screen display method.

[0088] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of rectangular parameters, screen length, height of local display areas, etc., all comply with relevant laws and regulations and do not violate public order and good morals.
