Description

Technical Field

[0001] The utility model relates to the field of phantom imaging devices, in particular to a lifting type virtual-real combined stereoscopic imaging mechanism. Background Art

[0002] The existing phantom imaging system is generally composed of an imaging system, light and shadow reflection, real scene and sound system, forming a three-dimensional picture with clear layers, giving the audience a real viewing experience of "real-time performance" and "real happening". For example, Chinese patent application CN201610335788.0 discloses a naked-eye 3D imaging device using a phantom imaging film, which is a fixed position projection for mapping. Chinese patent application CN201920292729.9 discloses a 3D virtual holographic phantom imaging device for various demonstrations. This technology solves the problems of imaging ghosting and unclearness.

[0003] However, the existing phantom imaging systems are all fixed in structure and are similar. Aluminum-coated film projections cannot be raised or lowered, and there is a problem that the depth of the picture cannot be changed and the three-dimensional sense of the picture space is poor.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The utility model aims to provide a lifting type virtual-real combination stereoscopic imaging mechanism, which can realize the lifting of the aluminum film projection to change the depth of the picture, enhance the three-dimensional sense of the picture space, and thus solve the above technical problems existing in the prior art.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A lifting type virtual-real combined stereoscopic imaging mechanism, comprising:

[0008] A fixed LED screen, at least one lifting platform, an oblique aluminum film imaging device and a lifting LED screen; wherein,

[0009] The fixed LED screen is arranged at the end farthest from the auditorium and can display scene images;

[0010] Each lifting platform is arranged in sequence and at intervals in front of the fixed LED screen, and can carry and lift actors and change real scenes;

[0011] The oblique aluminum film imaging device is obliquely arranged in front of the lifting platform, in front of the auditorium, and inclined toward the auditorium.

[0012] The lifting type LED screen is arranged below the oblique aluminum-coated film imaging device. The LED display screen of the lifting type LED screen is arranged horizontally, and the horizontally arranged LED display screen can be lifted and lowered.

[0013] Compared with the prior art, the lifting type virtual-real combined stereoscopic imaging mechanism provided by the utility model has the following beneficial effects:

[0014] By setting up a lifting LED screen and an oblique aluminum-film imaging device, the lifting LED screen can drive the horizontally set LED display screen to move up and down, so that the projection image on the aluminum film of the oblique aluminum-film imaging device also becomes larger or smaller, making the virtual imaging surface closer or farther from the audience, creating the size and distance effect of the image, that is, the depth of the picture, increasing the depth experience, and enhancing the three-dimensional sense of the picture space. The imaging mechanism of this structure projects the display content through the aluminum film into the stage space by lifting the LED screen up and down. The picture has a sense of depth and three-dimensionality. Combined with real-life performances and real scenes, it realizes the visual feeling that real people and animation characters exist in the same three-dimensional space, and then can realize the creation of many surreal film and television stories, which well solves the problem that the aluminum-film projection in the traditional phantom imaging system cannot be lifted and lowered, has no sense of depth and three-dimensionality, and has great limitations.

[0055] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the lifting type virtual-real combined stereoscopic imaging mechanism provided by the present invention is described in detail with reference to specific embodiments below.

[0056] Example 1

[0057] like Figure 1 As shown, the embodiment of the utility model provides a lifting type virtual-real combined stereoscopic imaging mechanism, comprising:

[0058] Fixed LED screen 1, first lifting platform 5, second lifting platform 6, lifting type LED screen 3 and oblique aluminum film imaging device 2; wherein,

[0059] The fixed LED screen 1 is fixedly arranged at the outermost side of the entire stage, that is, at the end away from the auditorium 8, with one side of the screen facing forward to display the scene picture;

[0060] The first lifting platform 5 is arranged in front of the fixed LED screen 1 at intervals and is used for lifting actors and replacing part of the real scene;

[0061] The second lifting platform 6 is arranged in front of the first lifting platform 5 at intervals to cooperate with the lifting point to change the real scene;

[0062] The oblique aluminum film imaging device 2 is arranged in front of the second lifting platform 6, close to the auditorium 8, and is installed on the steel structure on the left side of the highest point of the lifting LED screen 3 at an angle of 45 degrees, starting from the bottom of the inside and rising to the outside.

[0063] The lifting type LED screen 3 is arranged below the oblique aluminum-coated film imaging device 2. The LED display screen of the lifting type LED screen 3 is arranged horizontally, and the horizontally arranged LED display screen can be lifted and lowered.

[0064] In the above imaging mechanism, when the lifting type LED screen 3 is at the highest point of the lifting, its LED display screen and the lowermost end of the oblique type aluminum-coated film imaging device 2 are in the same plane, and the imaging plane 4 perpendicular to the LED display screen formed by the oblique type aluminum-coated film imaging device 2 is at the far end behind the oblique type aluminum-coated film imaging device 2;

[0065] When the lifting LED screen 3 is at the lowest point, its LED display screen is away from the plane where the lowest end of the oblique aluminum-coated film imaging device 2 is located, and the imaging plane 4 perpendicular to the LED display screen formed by the oblique aluminum-coated film imaging device 2 is located at the proximal end behind the oblique aluminum-coated film imaging device 2.

[0066] The fixed LED screen 1 in the above-mentioned imaging mechanism is supported by a steel frame at the back. The steel frame is built with square tubes that are crisscrossed vertically and horizontally, and a part is extended horizontally and on the left and right sides to form a cube to improve the support of the steel frame standing on the ground. The square tubes inserted obliquely on the inside of these cubes are supported to improve stability; at the same time, two square tubes are extended from both sides of the back to form a V-shaped support, which is welded to the steel plate fixed with bolts on the wall; a maintenance ladder is set on the first and second floors on the left side of the steel frame, a maintenance ladder is set on the second and third floors in the middle of the steel frame, and a maintenance ladder is set on the third and fourth floors on the right side of the steel frame to facilitate subsequent maintenance of the LED screen.

[0067] The first lifting platform 5 in the above-mentioned imaging mechanism can be rotated by the motors on the left and right sides, and the entire platform can be lifted and lowered by the chain. It is a motor-driven chain-type mechanical lifting device.

[0068] The second lifting platform 6 in the above imaging mechanism is hydraulically lifted, and preferably a circular lifting platform is used.

[0069] The lifting LED screen 3 in the imaging mechanism is made of a steel frame with square tubes interlaced vertically and horizontally as a bracket 32, and the side view is H-shaped. The bracket 32 ​​and the LED display screen 31 are fixed by screws through them. The lifting device 33 responsible for lifting is similar in structure to the first lifting platform, and is a motor-driven chain-type mechanical lifting device. In general, the fixed LED screen 1 displays the background scene, and the lifting LED screen 3 displays the storyline and other content. By lifting up and down, the displayed content is projected through the aluminum film onto the imaging surface 4 formed in the stage space.

[0070] The oblique aluminum film imaging device 2 in the above-mentioned imaging mechanism is installed as a whole at an angle of 45° to the side of the lifting LED screen 3. Specifically, when the lifting LED screen 3 rises to the highest position, the side away from the audience serves as the fulcrum for installing the aluminum film 22, and is inclined upward at an angle of 45° along the side close to the auditorium 8. The left and right sides of the bottom of the aluminum film 22 have oblique support brackets as oblique support devices 23. The lower ends of the oblique support brackets are fixed to the left and right sides of the stage by bolts. The two sides of the back are aluminum film steel frame structures serving as aluminum film brackets 21. The lower left corner is used as the fulcrum, and the upper right corner pulls the top of the aluminum film to stabilize the overall position of the aluminum film.

[0071] In summary, it can be seen that the imaging mechanism of the embodiment of the utility model, through the cooperation of the lifting LED screen and the oblique aluminum-coated film imaging device, the picture has a three-dimensional sense of depth, can be forward or backward, and has high flexibility. Combined with the fixed real scene set on the stage, and the real-life performances and replaceable real scenes on the first lifting platform and the second lifting platform, a very shocking three-dimensional sense of reality is formed in the eyes of the audience, achieving the feeling that real people and cartoon characters exist in the same three-dimensional space visually, and can realize the creation of many surreal film and television stories.
