Description

Technical Field

[0001] This utility model relates to the field of globe technology, and in particular to a dynamic globe based on projection. Background Technology

[0002] A globe is a tool for displaying geographical information, commonly used in teaching and for finding geographical information. Traditional globes only have the simple function of manually rotating to view a fixed map, but they have at least the following shortcomings: because the geographical image being viewed is fixed and cannot be changed, they lack the ability to present dynamic images in real time. Simulating the Earth's rotation requires manual rotation of the globe; the geographical images cannot rotate automatically.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic globe based on projection, which can display images of the Earth in an intuitive, dynamic, and rotating manner, thereby solving the aforementioned technical problems in the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A dynamic globe based on projection, comprising:

[0007] Hollow imaging sphere and projection equipment; among which,

[0008] The hollow imaging sphere has an opening at its bottom;

[0009] The projection device is located at the bottom opening of the hollow imaging sphere, with the fisheye lens of the projection device facing the top inside the hollow imaging sphere. It can project the dynamic image of the sphere onto the imaging rear projection film inside the hollow imaging sphere, so that the outer surface of the hollow imaging sphere displays the corresponding complete dynamic image of the sphere.

[0010] Compared with existing technologies, the dynamic globe based on projection provided by this invention has the following advantages:

[0011] By placing a projection device at the bottom of a hollow imaging sphere and positioning the fisheye lens of the projection device towards the top of the hollow imaging sphere, the projection device can project a dynamic image of the sphere into the hollow imaging sphere, thus displaying a corresponding dynamic image of the complete sphere on the outer surface of the hollow imaging sphere. This globe achieves the effect of displaying dynamic images on the surface of the globe through projection, providing an intuitive, dynamic, and rotating display of images related to the Earth.

[0026] like Figure 1As shown, this utility model provides a dynamic globe based on projection, comprising:

[0027] Hollow imaging sphere 1 and projection device 2; wherein,

[0028] The bottom of the hollow imaging sphere 1 is provided with an opening 13;

[0029] The projection device 2 is located at the bottom opening 13 of the hollow imaging sphere 1. The fisheye lens of the projection device faces the top inside the hollow imaging sphere 1 and can project the dynamic image of the sphere onto the imaging back projection film 12 inside the hollow imaging sphere 1, so that the outer surface of the hollow imaging sphere 1 displays the corresponding complete dynamic image of the sphere.

[0030] See Figure 2 , Figure 3 Preferably, in the above-mentioned dynamic globe, the hollow imaging sphere 1 is composed of a hollow transparent glass sphere 11 and the imaging back projection film 12 coated on the inner surface of the hollow transparent glass sphere 11.

[0031] The bottom of the hollow transparent glass sphere 11 is provided with the opening 13 for installing the projection device 2.

[0032] Preferably, in the above-mentioned dynamic globe, the projection device includes: a micro projector 21 and the fisheye lens 22; wherein,

[0033] The fisheye lens 22 is mounted at the lens position of the micro projector 21, and the fisheye lens 22 faces the top of the hollow imaging sphere 1 from bottom to top.

[0034] Preferably, in the above-mentioned projection device, the fisheye lens 22 is a 160° fisheye lens. This angle of the fisheye lens can meet the requirement of viewing the entire inner surface of the hollow imaging sphere 1 to obtain a complete dynamic spherical image.

[0035] See Figure 4 , Figure 5 The aforementioned projection device also includes an image server 3, which is communicatively connected to the projection device 2 and can send dynamic images of the sphere to the projection device 2.

[0036] In summary, the dynamic globe provided by this utility model, by setting a projection device at the bottom opening of the hollow imaging sphere, uses the fisheye lens of the projection device to project the dynamic image of the sphere onto the imaging rear projection film on the inner surface of the hollow imaging sphere, and then displays the projected dynamic image on the display surface on the outer surface of the hollow imaging sphere. Since the image can be easily switched, it solves the problem of the single image of traditional globes, and can achieve the effect of intuitively, dynamically, and rotatingly displaying relevant images of the earth.

[0037] To more clearly demonstrate the technical solution and its effects provided by this utility model, the following detailed description of the solution provided by the embodiments of this utility model is provided with reference to specific examples.

[0038] Example 1

[0039] This embodiment provides a dynamic globe based on projection, capable of dynamically displaying different images, forming a completely new form of globe presentation, and subverting the traditional way of globe presentation, such as... Figure 1 As shown, the dynamic globe includes:

[0040] Hollow imaging sphere 1 and projection device 2; wherein,

[0041] The bottom of the hollow imaging sphere 1 is provided with an opening 13;

[0042] The projection device 2 is located at the bottom opening 13 of the hollow imaging sphere 1. The fisheye lens of the projection device faces the top inside the hollow imaging sphere 1 and can project the dynamic image of the sphere onto the imaging back projection film 12 inside the hollow imaging sphere 1, so that the outer surface of the hollow imaging sphere 1 displays the corresponding complete dynamic image of the sphere.

[0043] The above-mentioned hollow imaging sphere 1 is constructed as follows: Figure 2 As shown, an imaging rear projection film 12 is formed on the inner surface of a hollow transparent glass sphere 11 with an opening 13 at the bottom using a coating technology. When an image is projected onto the imaging rear projection film, the corresponding image is displayed on the display surface of the outer surface of the hollow glass sphere. For a specific effect, please refer to [reference needed]. Figure 3 The opening at the bottom of the hollow transparent glass sphere 11 serves two purposes: it facilitates the spraying of the rear projection film 12 inside the hollow transparent glass sphere 11, and it also facilitates the subsequent installation of the projection equipment 2.

[0044] The aforementioned projection device 2 consists of a miniature projector 21 and a 160-degree fisheye lens 22 that projects the image (see [link]). Figure 3 It can project a complete spherical dynamic image inside a hollow, transparent glass sphere.

[0045] The projection device 2 in this embodiment can store dynamic image data itself, or provide dynamic image data through external storage devices such as USB flash drives, memory cards, or memory devices, or it can connect to the Internet and obtain images from cloud servers.

[0046] Example 2

[0047] See Figure 4 , Figure 5This embodiment provides a dynamic globe based on projection. The structure of the hollow imaging sphere 1 and the projection device 2 is the same as in Embodiment 1, except that it also includes an image server 3, which is communicatively connected to the projection device 2 and can send dynamic images of the sphere to the projection device 2. Specifically, it is communicatively connected to the micro projector of the projection device 2. Preferably, image processing software can be pre-screened within the image server. The software performs real-time dynamic image segmentation, deformation correction, and stitching processing on the image to be sent to the projection device 2 before transmitting it to the projection imaging system for playback.

[0048] The workflow of the dynamic globe in this embodiment is as follows:

[0049] 1) Turn on the power to the projection device 2 and the image server 3, and run the image processing software;

[0050] 2) Input the images that need to be displayed by the dynamic globe into image processing software for real-time processing (cutting, correction of deformation, etc.);

[0051] 3) Transmit the processed image to projection device 2;

[0052] 4) Projection device 2 projects corresponding dynamic images onto the inner wall of hollow imaging sphere 1 through fisheye lens 22;

[0053] 5) The viewer views the image from outside the hollow imaging sphere 1.

[0054] In summary, the dynamic globe of this invention can be used not only to display traditional geographical and meteorological information related to the Earth, such as atmosphere, topography, cloud maps, and landforms, but also to display other spherical images (such as the real-time dynamic distribution of global shipping vessels and aircraft flights).

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims. The information disclosed in the background section is intended only to enhance the understanding of the overall background technology of this utility model and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art.
