Description

A high-definition video transmission device for drones Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a high-definition video transmission device for UAVs. Background Technology

[0002] Currently, the technologies for stabilizing footage on drones equipped with cameras mainly fall into two categories: mechanical gimbal stabilization and electronic image stabilization algorithms. While these technologies have solved the problem of image shakiness to some extent, they still have significant shortcomings in complex flight environments, equipment compatibility, and cost control.

[0003] The technical principle of mechanical gimbal stabilization technology is to adjust the camera's attitude in real time through a three-axis brushless motor gimbal (pitch, roll, and yaw axes) to counteract attitude changes during drone flight. Representative products include DJI's Zenmuse series gimbals. However, its limitations lie in weight and power consumption: the gimbal motors and control modules account for 15%-20% of the total weight, severely compressing the drone's flight time (by an average of 25%); rigidity dependence: the gimbal and the body adopt a separate design, and vibration energy is transmitted through a rigid connection, requiring additional vibration damping structures for high-frequency resonance; and high cost: professional-grade three-axis gimbals can cost 30%-50% of the total price of the drone, making it difficult to popularize in industrial-grade or low-cost drone fields.

[0004] The technical principle of Electronic Image Stabilization (EIS) algorithms is to analyze image shake in real time using image sensor data and compensate for displacement using algorithms such as digital cropping and inter-frame interpolation. For example, GoPro's "HyperSmooth" technology can identify and eliminate low-frequency shaking. Limitations include: Image quality loss: The algorithm needs to crop the edges of the image to compensate for shake, resulting in a 10%-30% decrease in effective resolution; 4K video may be downgraded to below 2K. Dynamic response latency: The algorithm requires a 1-3 frame delay, and in high-speed flight or severely turbulent scenes, the image may still appear blurry or have motion blur. Hardware dependence: High-precision image stabilization requires high-performance processor support, increasing device power consumption and heat generation, especially in high-temperature environments where overheating protection is easily triggered, limiting continuous working time.

[0005] The common shortcomings of existing technologies are: although mechanical gimbals can achieve high-precision stability, their weight and power consumption limit the maneuverability of drones. Traditional gimbals require customized clamps for specific camera models, while universal clamping devices (such as screw fixing) are cumbersome to adjust and cannot be quickly adapted to devices of different sizes, reducing mission flexibility. It is difficult to ensure stable image quality while taking into account lightweight equipment, environmental robustness, and rapid adaptability. Therefore, it is necessary to design a drone high-definition video transmission device with strong practicality and rapid adaptability. Summary of the Invention
