Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0020] In the description of the present invention, reference to an "embodiment" means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the described embodiments may be combined with other embodiments.

[0021] Traditional camouflage technology mainly uses camouflage paint and camouflage color, which is achieved by hanging camouflage cloth on the outside of the tent and painting camouflage paint on equipment. However, camouflage paint and camouflage color can only have a certain camouflage effect under specific circumstances. It is difficult to achieve ideal visual camouflage and cannot adapt to the environment.

[0022] Most of the existing building camouflage solutions achieve camouflage by mounting a display screen on the outer surface of the stealth target. However, due to the limitations of the display screen's frame, the camouflage effect is less than ideal. In addition, since the size of the display screen itself cannot be changed, this solution is not suitable for complex building surfaces.

[0023] In order to solve the above problems, the present invention provides a building stealth system.

[0024] The specific embodiments are described in detail below: The embodiment of the present invention provides a building stealth system, combined with Figure 1 Come and see, Figure 1 This is a schematic diagram of the structure of an embodiment of a building stealth system provided by the present invention. The building stealth system 100 includes: The acquisition module 101 is used to acquire the model data of the building and the scene data near the building; A control module 102, connected to the acquisition module 101, configured to receive the model data and the scene data, and generate a first control instruction and a second control instruction based on the model data and the scene data; A projection module 103, connected to the control module 102, configured to receive a first control instruction and project an image onto the building based on the first control instruction; The reflection adjustment module 104 is connected to the control module 102, and is used to receive a second control instruction, and adjust the electrochromic film covering the outer surface of the building and the indoor lighting intensity of the building based on the second control instruction.

[0025] During implementation, the control module can first control the acquisition module to obtain the model data of the building and the scene data near the building. Then the control module can receive the model data and the scene data, determine the picture to be projected, and render and distribute the projection picture. At the same time, it can generate a first control instruction and a second control instruction, and send the first control instruction to the projection module, and send the second control instruction to the reflection adjustment module.

[0026] After receiving the first control instruction, the projection module can project the image to the building according to the first control instruction. After receiving the second control instruction, the reflection adjustment module can adjust the reflection performance of the outer surface of the building according to the second control instruction.

[0027] The reflection adjustment module may include a building surface reflection module and an indoor lighting module. The building surface reflection module may cover the surface of the building (including skylights, window glass, etc.) with electrochromic thin film materials, and change the color and brightness of the building surface to better adapt to the projection image of the projection module, thereby improving the effect of the integration of the building and the environment. The indoor lighting module may improve the effect of the integration of the building and the environment by adjusting the lighting intensity indoors. The reflection adjustment module adjusts the reflection performance of the outer surface of the building according to the second control instruction, that is, adjusts the electrochromic thin film material covering the surface of the building and the lighting intensity indoors of the building according to the second control instruction, thereby realizing the adjustment of the reflection performance of the outer surface of the building.

[0028] The building stealth system provided by the present invention can be applied to small-format building stealth scenes or large-format building stealth scenes, and the present invention does not make specific limitations on this.

[0029] Compared with the prior art, the building stealth system provided in this embodiment determines the image projected onto the building through the model data of the building and the scene data near the building, and can also adjust the reflective performance of the outer surface of the building to achieve the integration of the building and the environment, realize the stealth of the building, and ensure the stealth effect of the building.

[0031] Specifically, the surfaces of the acquisition module and the projection module of the present invention are also covered with an electrochromic film. The control module can also control and adjust the reflective performance of the electrochromic film covering the surfaces of the acquisition module and the projection module according to the model data and the scene data, thereby providing a basis for the subsequent realization of the stealth of the acquisition module and the projection module.

[0036] The first sub-instruction can control the AGV to move on the ground according to a preset route, the second sub-instruction can control the multi-degree-of-freedom manipulator to move in the horizontal and vertical directions according to a preset track, and the third sub-instruction can control the transmitting module to project a preset picture. Through the first control instruction, each projection sub-module in the projection module can be controlled to project the picture to the preset position of the building, thereby realizing the camouflage of the building.

[0037] Exemplarily, a plurality of positioning modules are provided on the building, and surfaces of the plurality of positioning modules are covered with an electrochromic film; The multiple positioning modules are used to transmit positioning signals; The projection module is also used to receive the positioning signal and correct the angle of projecting the picture onto the building based on the positioning signal.

[0038] Specifically, in order to improve the accuracy of the projection module projecting the picture, multiple positioning modules can be set on the building. At the same time, in order not to affect the camouflage effect of the building, the surface of the positioning module can be covered with an electrochromic film. The positioning module can emit a positioning signal, and the positioning signal is emitted in the form of invisible light to avoid affecting the camouflage effect of the building. After receiving the positioning signal, the projection module can correct the angle of the projection image to the building according to the positioning signal, thereby improving the accuracy of the projection module projecting the picture.

[0039] A specific embodiment of the present invention also discloses a building stealth method, which is applied to the control module in the building stealth system as described above, combined with Figure 2 Come and see, Figure 2 The schematic diagram of the flow chart of an embodiment of the building stealth method provided by the present invention includes step S201 and step S202, wherein: In step S201, the acquisition module is controlled to acquire model data of a building and scene data near the building, and a first control instruction and a second control instruction are generated based on the model data and the scene data; In step S202, the projection module is controlled to project an image onto the building based on the first control instruction, and the reflection adjustment module is controlled to adjust the electrochromic film covering the outer surface of the building and the indoor lighting intensity of the building based on the second control instruction.

[0040] During implementation, the control module may first control the acquisition module to obtain the model data of the building and the scene data near the building, and then generate the first control instruction and the second control instruction according to the model data and the scene data.

[0041] Then, the projection module can be controlled according to the first control instruction to project the image onto the building, and the reflection adjustment module can be controlled according to the second control instruction to adjust the electrochromic film covering the outer surface of the building and the indoor lighting intensity of the building, thereby realizing the invisibility of the building.

[0042] The building stealth method provided by the present invention can be applied to small-format building stealth scenes or large-format building stealth scenes, and the present invention does not make specific limitations on this.

[0043] Compared with the prior art, the building stealth method provided in this embodiment determines the image projected onto the building through the model data of the building and the scene data near the building, and can also adjust the reflective performance of the outer surface of the building to achieve the integration of the building and the environment, realize the stealth of the building, and ensure the stealth effect of the building. The image projection scheme can also adapt to complex building surfaces.

[0044] Exemplarily, the method further includes: The reflective performance of the electrochromic film covering the surfaces of the acquisition module and the projection module is controlled based on the model data and the scene data.

[0045] Specifically, the control module can also control and adjust the reflective performance of the electrochromic film covering the surface of the acquisition module and the projection module according to the model data and the scene data, thereby providing a basis for the subsequent realization of the stealth of the acquisition module and the projection module.

[0048] Exemplarily, the method further includes: The acquisition module is controlled to acquire the environmental change information near the building.

[0049] Specifically, the control module may also control the acquisition module to obtain the environmental change information near the building, so as to adjust the building stealth strategy at any time to ensure the long-term stealth requirement of the building.

[0050] Exemplarily, the method further includes: When the environment near the building changes, the stealth control of the building is re-performed.

[0051] Specifically, when the environment near the building changes, the control module can repeat the above steps to achieve building invisibility to ensure that the camouflage of the building remains effective.

[0052] The following is a specific application scenario to better illustrate the technical solution of the present invention: Combination Figure 3 Come and see, Figure 3 This is a flow chart of an embodiment of a building stealth process provided by the present invention. The process is as follows: 1. When there is a need for stealth, the drone will fly out with a compound eye camera to collect scene data and building model data and send it to the central control system. Figure 4 Come and see, Figure 4 A schematic structural diagram of another embodiment of the building stealth system provided by the present invention.

[0053] 2. The central control system generates projection images based on the collected data based on artificial intelligence algorithms, renders and distributes the projection images, and independently plans the position of the equipment and the projection angle of the stage lights, and sends the appropriate control parameters to the building reflection system and indoor lighting system.

[0054] 3. The building reflection system and indoor lighting system reach the predetermined parameter values, and glass materials such as windows become easy to reflect projection.

[0055] 4. The device arrives at the designated location and starts projecting the image.

[0056] (1) The equipment cabin is unfolded, the robotic arm is extended, and the visual sensor recognizes the invisible light markers on the building and accurately projects the image onto the building. The projected image also takes into account other equipment, and the mutual projection achieves visual invisibility. Figure 5 Come and see, Figure 5 This is a schematic diagram of an embodiment of the working scenario of the building stealth system provided by the present invention. "AGV+multi-DOF robotic arm+high-power stage light" achieves the purpose of visual stealth by projecting stealth images distributed around high-rise buildings, and achieves the stealth of stealth presentation equipment and collection equipment by projecting other equipment (other AGVs, drones equipped with compound eye cameras).

[0057] (2) Multi-projection image fusion is fed back through the visual sensors on the equipment and the central control system to perform multi-projection image fusion correction; (3) The fusion of multiple projection images is completed, and the surface projection and the surrounding environment are integrated; 5. Visual invisibility is completed, and the compound eye camera acquisition system continues to collect information about the surrounding environment. If there are any changes, repeat steps 2, 3, and 4.

[0058] For long-term invisible projection, the above process uses "AGV + multi-degree-of-freedom robotic arm + high-power stage light" to rotate and charge to achieve long-term operation. The drone equipped with compound eye camera also works in the form of rotation charging. Figure 6 Come and see, Figure 6 This is a flow chart of an embodiment of the cyclic operation of the projection module provided by the present invention. During the construction of the invisible building, the "AGV+multi-DOF robotic arm+high-power stage light" system and the compound eye camera acquisition system determine whether their own power can support the work, and realize continuous work through the cyclic / iterative work of the backup equipment and the working equipment to ensure the stability of the invisible system.

[0059] Combination Figure 7 Come and see, Figure 7 This is a structural schematic diagram of an embodiment of the working state of the projection submodule provided by the present invention. When the "AGV+multi-degree-of-freedom robotic arm+high-power stage light" equipment is working, the robotic arm drives the stage light to extend out from the cabin, the AGV is tracked, and the cabin cover is retracted on both sides of the cabin through the connecting rod and rocker mechanism. The coordinated movement of the AGV and the multi-degree-of-freedom robotic arm drives the high-power stage light to move to adjust the projection angle of the stage light to achieve stealth.

[0060] Combination Figure 8 Come and see, Figure 8 This is a structural schematic diagram of an embodiment of the closed state of the projection sub-module light and shadow cabin provided by the present invention. When the "AGV+multi-degree-of-freedom robotic arm+high-power stage light" is not in working state, the robotic arm is stored in the cabin, and the entire equipment is moved to the equipment vehicle through the AGV and connected to the charging interface for automatic charging so as to continue to operate in a cycle.

[0061] The present invention can achieve the invisibility of large-scale building groups, and perform visible light visual invisibility through projection, which is closer to natural display and has better camouflage effect. In addition, the solution has good scalability and can be used for small-scene invisibility as well as large-scale invisibility.

[0062] The present invention also realizes the stealth of the projection device and the acquisition device, and there is no need to consider placing the acquisition device outside the stealth target to affect the acquisition effect. The solution provided by the present invention has low power consumption, can intelligently construct stealth, and does not require complicated operations.

[0063] In addition, the solution provided by the present invention has strong adaptability. Since the projection is realized without the aid of a projection surface of a specific shape, it can well adapt to complex surfaces and complete invisible projection.

[0064] The present invention discloses a building stealth system and method, which determines the image projected onto the building through the model data of the building and the scene data near the building, and can also adjust the reflective performance of the outer surface of the building to achieve the integration of the building and the environment, realize the stealth of the building, and ensure the stealth effect of the building. The image projection scheme can also adapt to complex building surfaces. The present invention can adapt to complex building surfaces while ensuring the camouflage effect of the building, thereby improving the flexibility of the building camouflage scheme.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
