Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle performance equipment, and in particular to a formation unmanned aerial vehicle projection imaging system and a projection imaging method thereof. Background Art

[0002] In recent years, the booming development and manufacturing of civil aircraft has provided new opportunities for formation drones. Due to the convenience of information technology and the gradual industrialization of commercial performances of formation drones, traditional formation drones perform by hanging LED light-emitting devices in the night sky. Each drone has only one light point, and the form of such performances is relatively simple; or they carry smoke-pulling devices and fly during the day to pull smoke, directly pulling smoke of different shapes and colors in the air, but such performances cannot produce obvious viewing effects in the night sky.

[0003] Traditional commercial performance methods can no longer adapt to the development of industrialization. New performance content and forms are urgently needed. If a whole screen is carried into the air, the difficulty coefficient is extremely high. It not only increases the risk of the screen falling, but also the screen's own weight makes the formation drone overloaded, the battery power consumption is too large, and there are other technical limitations. Traditional formation drones cannot be presented to the audience in the form of pictures or videos during commercial performances.

[0004] Therefore, it is necessary to propose a formation UAV projection imaging system and a projection imaging method thereof to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to improve the defects of the prior art and provide a formation UAV projection imaging system and a projection imaging method thereof.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0007] The method for projection imaging of formation UAVs comprises the following steps: laying out a number of UAVs and forming a formation UAV; controlling the formation UAVs to take off by a control device; adjusting and aligning the heading angles of the formation UAVs; controlling the adjusted and aligned formation UAVs to fly to a designated airspace, and arranging the array formation of the formation UAVs; causing the formation UAVs after the array formation is arranged to continuously hover in the designated airspace in the night sky; starting a projection system, rotating the projection direction of the projection system toward the formation UAVs in the designated airspace; automatically identifying and aligning the UAVs located at the center point of the array formation; the control device emits an ignition signal, and a smoke generator continuously sprays smoke after receiving the ignition signal; taking the aligned UAV as the projection midpoint, projecting the projection content onto the smoke, and due to the reflection of light, the smoke reflects the projection content.

[0008] Before the formation drones take off, the following steps are also included: recording the pre-set projection content into the memory space of the projection system; the projection system outputs the aspect ratio of the projection content, and the control device obtains the aspect ratio of the projection content.

[0009] When the formation drones fly to the designated airspace, the following steps are also included: the array formation of the formation drones is arranged into an array formation with a corresponding aspect ratio through a control system according to the different aspect ratios of the projection content.

[0010] The control device obtains the aspect ratio of the corresponding projection content from the projection system, and is used to control the formation drones to arrange an array formation corresponding to the aspect ratio of the projection content, and then make adaptive adjustments to the projection content. When the projection system is projecting, it can be projected normally, further preventing the loss of part of the projection content, unclear projection, and other situations that require temporary repairs during the performance.

[0011] The direction of the reflected projection content is opposite to the viewing direction.

[0012] The reflection direction opposite to the viewing direction can reflect clearer projection content to the audience, so that the audience can clearly watch the projection content, further improving the clarity and resolution of the projection content.

[0013] The projection content includes one of a picture, an animation or a video clip.

[0014] The content of pictures, animations or video clips can be projected onto the smoke by the projection system, adding a lot of colorful projection content to the commercial performances of formation drones, further providing content creators with a very good creative space.

[0015] The smoke generator continuously sprays smoke for a period of 3 minutes to 15 minutes, and the smoke spraying time is adjusted accordingly according to the projection duration of the projection system.

[0016] The smoke generator can spray smoke continuously for 3 to 15 minutes, so that the projection content reflected by the smoke can be continuously presented in the night sky, giving users more creative freedom in choosing the projection duration.

[0017] A formation UAV projection imaging system, comprising a control device, a formation UAV, a smoke generator, and a projection system, wherein the control device is electrically connected to the smoke generator, the formation UAV comprises a plurality of UAVs, the projection system is electrically connected to the control device, and a gap for retaining smoke is provided between two adjacent UAVs;

[0018] The control device is used to control the formation drones to take off; to adjust and align the heading angles of the formation drones; to control the formation drones to fly to a designated airspace and arrange the array formation; to control the formation drones to continue hovering in the designated airspace; and to provide an ignition signal for transmission;

[0019] The smoke generator is used to receive an ignition signal and to continuously spray smoke;

[0020] The projection system is used to project projection content onto the smoke, and the smoke is used to reflect the projection content.

[0021] The projection device includes an identification control module, a projection module, a communication module, and a drive motor. The projection module and the drive motor are both electrically connected to the identification control module, and the communication module is communicatively connected to the control device; the identification control module is used to calculate and obtain the aspect ratio of the projection content; and is used to automatically identify and align the drone with the center point; the projection module is used to project the projection content; the communication module is used to output the aspect ratio of the projection content; and the drive motor is used to drive the projection module to rotate and thereby adjust the projection direction of the projection module.

[0022] The projection direction of the projection module is toward the formation UAVs located in the designated airspace.

[0023] The projection module is set to face the formation drones in the designated airspace, which can ensure that the projection content is directly projected onto the smoke continuously ejected by the smoke generator during projection.

[0024] In the projection direction of the projection system, the overall shape of the smoke continuously ejected by the smoke generator is a rectangle, and the area of ​​the rectangle ranges from 10 square meters to 700 square meters.

[0025] Since the aspect ratio of photos and video clips in the projection content is generally rectangular, the rectangular smoke spray can better adapt to the aspect ratio of the projection content, further improving the adaptability of the formation drone projection imaging system during use.

[0026] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0027] The formation drones hover in a designated airspace in the night sky and continuously spray smoke. The projection system automatically identifies the drone at the center of the array formation before projection, avoiding projection deviation that makes part of the projection content unable to be presented to the audience, thereby improving the stability of the formation drone projection imaging method; when the projection system projects the projection content onto the smoke, the smoke reflects the projection content, and then clearly presents the projection content to the audience, so that the commercial performances of the formation drones can present projection content in the form of pictures, videos, etc., which greatly enriches the performance content and form of the formation drones, and the longer the smoke generator sprays smoke, the longer the projection content reflected by the smoke can last, which adds a lot of imagination to the creation of projection content, so as to more widely adapt to the industrial development of commercial performances of formation drones.
