Description

Technical Field

[0001] The utility model relates to the technical field of air imaging, in particular to an air imaging device for an unmanned aerial vehicle. Background Art

[0002] Current air imaging technology utilizes the rotation of the fan screen's LED lamp beads in conjunction with a motor, using high-speed rotating fan blades and a precise LED light strip system to create 3D images or video effects that appear to be suspended in the air. Existing air imaging technology is commonly used in the advertising industry and takes advantage of the human eye's persistence of vision. When an object moves quickly, the image seen by the human eye briefly remains in view. Through the high-speed rotating fan blades, the trajectory of the LED light strips in the air forms a continuous image in the human eye, which is usually fixed to a wall or in a window for people to view. Because the existing fan screen technology has a high-speed rotating motor, it must be placed out of reach of people or protected by a transparent cover to avoid being injured by the cantilever driven by the motor.

The input end of the connecting power line 301 is connected to the battery 160, and the output end is connected to the first motor 304 and the LED light sheet 312.

[0030] After the intelligent UAV takes off, the air imaging fan screen receives the startup signal, which activates the fan motor and begins to rotate. The air imaging fan screen then plays the image and text information received by the receiver or stored on the fan screen's memory card. The air imaging fan screen can be installed on the bottom or side of the intelligent UAV. By combining the intelligent UAV with an LED imaging fan, 3D air imaging is achieved. Precisely controlling the on / off sequence of the LED light strips during rotation creates a complete 2D slice image within one rotation. By stacking multiple slice images, a three-dimensional 3D image is presented. Multiple LED light strips are mounted on the rotatable fan blades, capable of high-speed rotation and emitting light at specific locations and times. A control system manages the LED light strip on / off sequence, fan speed, and synchronization with the UAV's flight control system, connecting to the user via wireless transmission. High-quality UAV products ensure that the drone maintains extreme stability while hovering or flying, preventing the vibration of the rotating fan from affecting image quality. The target 3D image is segmented into several 2D slices, each corresponding to a specific angle during the rotation of the LED light strip. The control system and the drone's information receiver transmit these slice images in real time via the 5.8G frequency band at a transmission rate of 6Mbps. The files are formatted as images or videos in bmp format. The control system precisely controls the lighting timing of the LED light strip based on the fan's rotation angle. Whenever the fan reaches a certain angle, the LED light strip illuminates specific LEDs to visually represent the corresponding slice image. The fan's rotation speed and the LED light strip's lighting frequency are synchronized to ensure a complete 3D image is rendered within each rotation cycle. Through rapid rotation, multiple slice images are stacked in mid-air to form a complete 3D image. Due to the human eye's persistence of vision, viewers perceive a continuous, integrated 3D image. The integration of intelligent unmanned aerial vehicles (UAVs) and air-imaging fan screens expands the applications of both intelligent UAVs and air-imaging fan screens.

[0031] In actual applications, to ensure that the fan screen does not affect the flight stability and endurance of the drone, the material and structure of the fan screen are first designed to be lightweight to reduce the impact on the overall weight of the drone. Lightweight but strong materials (such as carbon fiber, plastic composite materials, etc.) are used to make the fan screen components. Among them, choosing a high-efficiency, low-power motor to drive the fan screen can minimize the load on the drone battery while ensuring sufficient speed and brightness. At the same time, the drone's power management system is used to dynamically adjust the power consumption of the fan screen. When the drone's battery is low, the brightness or rotation speed of the fan screen is reduced to extend the flight time. Finally, a shock-absorbing device (such as a rubber gasket or shock-absorbing mount) is installed between the fan screen and the drone body to reduce the transmission of vibration to the drone's fuselage, thereby improving flight stability. At the same time, the drone's flight control system is optimized for the dynamic characteristics of the fan screen and adjusts the attitude control algorithm to deal with the tiny disturbances caused by the rotation of the fan screen. The wireless signal receiving device of the air imaging fan screen can be shared with the intelligent unmanned aerial vehicle, or it can be a separate module. The wireless communication module of the unmanned aerial vehicle can also be used to convert the picture or video content into the wireless signal required by the air imaging fan screen. Through the combination of applications, it can achieve a large-scale display of picture and video signals, give full play to the advantage of the fast response speed of the intelligent unmanned aerial vehicle, and can be used to display text and images in the air during disaster relief, temporary emergency avoidance notices in dangerous areas, and aerial guidance in crowded and noisy environments.

[0032] The core of the 3D holographic fan screen is a high-speed rotating LED screen composed of multiple LED light strips, each densely packed with LED light points. When the LED screen spins at extremely high speeds, the persistence of vision creates a continuous image in mid-air. The 3D holographic fan screen exploits this effect. Even though the LED lights illuminate in different positions during the rapid rotation, the human eye perceives a continuous image. The 3D image or video to be displayed is processed into multiple slices, each corresponding to a row of LED lights on the screen. As the screen rotates, each slice is rapidly displayed sequentially, forming a coherent 3D image. While the 3D holographic fan screen does not produce a true holographic image, it creates a holographic-like effect through specialized image processing and display technologies, making the image appear to float in mid-air and give it a three-dimensional feel. When used at close range, the 3D holographic fan screen is equipped with a control unit that receives and processes image signals via Bluetooth or Wi-Fi to control the on / off of the LED lights. When used at a long distance, the traditional 3D holographic fan screen can only transmit control signals over short distances via Bluetooth or WIFI. The UAV flies a long distance, which exceeds the reception range of Bluetooth and WIFI. The image files transmitted via 5G or 4G signals are received by the UAV, and the signal receiving and conversion function module carried by the UAV is converted into WIFI or Bluetooth signals, which are provided to the 3D holographic fan screen to achieve the effect of displaying 3D images at a long distance.
