The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] As mentioned earlier, the cost of using naked-eye 3D technology for exhibitions in exhibition halls is extremely high. Not only does it require the production of naked-eye 3D content, but it also requires the use of gratings or lenses to achieve 3D display. The structure is complex and the cost is high, making it unsuitable for large-scale and modular applications.

[0038] The present disclosure provides an exhibition hall projection splicing system, comprising: a three-dimensional projection screen, a plurality of supporting components, a projector array and a plurality of observation areas; the three-dimensional projection screen comprises a main screen, a side screen and a floor screen, the main screen and the side screen are arranged perpendicular to the ground, the side screen is arranged on the side of the main screen, the floor screen is arranged on the ground, and the main screen, the side screen and the floor screen are seamlessly spliced; the projector array comprises a plurality of projector groups, the plurality of projector groups and the plurality of supporting components are arranged correspondingly, different projector groups are fixedly arranged above the three-dimensional projection screen at different angles through corresponding supporting components, so as to seamlessly splice and display the content to be projected on the three-dimensional projection screen; the plurality of observation areas are arranged in front of or above the main screen.

[0039] The present invention can achieve a multi-angle and immersive exhibition hall viewing experience with a simple structure, and can achieve three-dimensional viewing without a complex grating or lens structure, thereby greatly reducing costs and achieving a more vivid exhibition hall content display.

[0040] Figure 1 A first view of an exhibition hall projection splicing system according to an embodiment of the present disclosure is shown. Figure 2 A second view of an exhibition hall projection splicing system according to an embodiment of the present disclosure is shown. Figure 3 A third view of an exhibition hall projection splicing system according to an embodiment of the present disclosure is shown.

[0041] like Figure 1-Figure 3As shown, the exhibition hall projection splicing system includes: a three-dimensional projection screen, a plurality of supporting components, a projector array and a plurality of observation areas 6.

[0042] According to an embodiment of the present disclosure, the stereoscopic projection screen includes a main screen 1, a side screen 2 and a floor screen 3. The main screen 1 and the side screen 2 are arranged perpendicular to the ground, the side screen 2 is arranged on the side of the main screen 1, and the floor screen 3 is arranged on the ground. The main screen 1, the side screen 2 and the floor screen 3 are seamlessly spliced.

[0043] In a specific embodiment, the number of the main screen 1 is 1, the number of the side screens 2 is 2, and the number of the floor screen 3 is 1. The main screen 1, the side screens 2, and the floor screen 3 can be screens of different shapes, as long as the shapes satisfy the seamless splicing between the main screen 1, the side screens 2, and the floor screen 3. For example, the main screen 1, the side screens 2, and the floor screen 3 are all rectangular screens, the long side of the main screen 1 is equal to the long side of the floor screen 3, and the wide side of the main screen 1 is equal to the long side of the side screen 2, so that the stereoscopic projection screen constitutes a stereoscopic three-dimensional structure.

[0044] According to an embodiment of the present disclosure, the main screen, the side screens and the floor screen are all walls coated with projection paint.

[0045] When the main screen, side screens and floor screen are all walls coated with projection paint, the use and maintenance costs can be reduced, and since less waste is generated during the use of the projection paint, it is more environmentally friendly.

[0046] According to an embodiment of the present disclosure, the main screen, the side screens and the floor screen are all one electronic screen or are composed of multiple electronic screens spliced ​​together.

[0047] When the main screen, side screens and floor screen are composed of multiple electronic screens, it can provide clearer and more realistic images, improve display quality, and have stronger interactivity, which helps the audience to obtain more comprehensive information and improve the display effect. At the same time, each electronic screen can be maintained and replaced independently without affecting the normal use of other parts.

[0048] According to an embodiment of the present disclosure, the projector array includes a plurality of projector groups, and the plurality of projector groups and the plurality of support components are arranged correspondingly. Different projector groups are fixedly arranged above the stereoscopic projection screen at different angles through corresponding support components to seamlessly splice and display the content to be projected on the stereoscopic projection screen.

[0049] According to an embodiment of the present disclosure, the projector array includes a plurality of forward projection groups 4 and a plurality of side projection groups 5; the plurality of support assemblies include a corresponding plurality of forward support assemblies and a plurality of side support assemblies.

[0050] For example, the plurality of front projection groups 4 include three front projection groups and two side projection groups.

[0051] The three forward projector groups specifically include a first forward projector group, a second forward projector group and a third forward projector group. The first forward projector group, the second forward projector group and the third forward projector group are fixed at a first angle, a second angle and a third angle respectively. The different fixed angles are the angles between the projectors in different forward projector groups and the horizontal line, that is, the fixed angles of each projector in the same forward projector group are the same.

[0052] The two side projection groups specifically include a first side projection group and a second side projection group, the first side projection group and the second side projection group are fixed at a fourth angle and a fifth angle respectively, the different fixed angles are the angles between each projector in different side projection groups and the vertical line, and similarly, the fixed angles of each projector in the same side projection group are the same. In a specific embodiment, the fourth angle is the same as the fifth angle.

[0053] Specifically, the first forward projection group is the projection group closest to the observation area 6, the third forward projection group is the projection group farthest from the observation area 6, and the second forward projection group is located between the first forward projection group and the second forward projection group. Then, the first angle of the first forward projection group is greater than the second angle of the second forward projection group, and the second angle of the second forward projection group is less than the third angle of the third forward projection group. The third angle can be 90 degrees. Each forward projection group can include 3 projectors, and each side projection group can include 2 projectors, but is not limited thereto.

[0054] When fixing the projector array, it is necessary to use a plurality of corresponding support components. The plurality of support components are described below with two specific embodiments. Those skilled in the art can understand that the two specific embodiments are not technical means for limiting the protection scope of the plurality of support components. For example, the plurality of support components can be implemented by any implementation method of the two specific embodiments alone, or by a combination of the two specific embodiments. For another example, the two specific embodiments are used to implement the forward support component and the lateral support component, respectively.

[0055] The inventors have found that most current projector support assemblies are designed with a fixed angle, which cannot be adjusted by the user during use. Although this design is simple, it cannot meet the usage requirements of different users in different occasions. Existing adjustable projector support assemblies are often composed of a support arm, a rotating shaft, and a tension knob. Although this projector support assembly can adjust the angle, it has poor stability, is prone to shaking, and has low safety.

[0056] Therefore, the present disclosure provides a projector support assembly that is adjustable in angle and stable in fixation, so as to meet the requirements of angle adjustment and safety of the projector during use.

[0057] According to an embodiment of the present disclosure, the plurality of support assemblies include a plurality of projector hangers, the number of which is not less than the sum of the number of projectors in the projector array. Each projector in the projector array is arranged above the stereoscopic projection screen via a projector hanger.

[0058] Each projector in the projector array is individually fixed at a set angle by using a plurality of projector hangers, so that the angle adjustment is more convenient and the fixing effect is more stable.
