With the opening up of the pandemic, the tourism industry is booming again, and aerial drones are becoming increasingly known to the public.
Compared to regular cameras, the biggest advantage of drones is that they can fly, capturing stunning images from a god’s-eye view, which has led many people to want to purchase their ideal aerial drone.
However, with so many brands on the market, how do you choose a drone that suits you?
Tips:
What is an aerial drone?
An aerial drone, formally known as Air Drive Airport, is a machine that can fly in the air, primarily used for taking photos or videos. Aerial drones typically consist of a flight control system, power system, remote control and receiving system, camera gimbal, and drone frame. Most aerial drones on the market today are multi-rotor drones.
How to choose an aerial drone?
When purchasing a good aerial drone, you need to consider factors such as safety and stability, aerial image quality, gimbal stabilization, transmission distance, and battery life.
Safety and Stability
The safety and stability of the drone is the first factor to consider before purchasing. No matter how good the lens and design of a drone are, if it is unstable, everything is in vain. After all, if you buy a drone that crashes shortly after flying, then you lose everything.
The safety and stability of a drone depend on its flight control system, gimbal system, transmission system, and obstacle avoidance system, all of which are important factors that distinguish different levels of drones.
Aerial Image Quality
Generally speaking, we buy aerial drones to capture stunning videos, so assessing the aerial image quality of the drone is also very important. To take satisfactory photos, the resolution is crucial, which requires the drone to capture images at high altitudes while maintaining clarity when enlarged. This requires at least 8 million pixels, meaning the camera resolution must reach at least 4K.
Gimbal Stabilization
In addition to image quality, the stabilization function of the drone’s gimbal is also an important factor to consider. The gimbal is the support device used to mount and secure the camera on the drone, and its stability is key to stable image capture. Currently, there are three main types of drone gimbals: fixed gimbals, two-axis mechanical gimbals, and three-axis mechanical gimbals.
Gimbal Analysis
-
A fixed gimbal directly connects the camera and drone, unable to flexibly change angles, resulting in poorer aerial image quality, usually equipped only on toy-grade drones.
-
A two-axis mechanical gimbal only compensates for horizontal camera movement, eliminating vertical stabilization to reduce power consumption. However, the stabilization effect is poor, commonly found on entry-level drones.
-
Mid to high-end drones typically come with three-axis mechanical stabilization gimbals, supplemented with EIS electronic stabilization, to ensure image stability. The three-axis mechanical gimbal primarily uses built-in gyroscopes and motors to control, providing counteracting forces to the camera in the X, Y, and Z axes during drone movement, preventing the camera from shaking with the drone, thus achieving stabilization.
Transmission Distance
The transmission distance determines the operational range of the drone. Within a certain transmission range, the drone’s camera can transmit real-time images to the operator’s phone or remote control screen.
The mainstream transmission methods for drones are primarily digital transmission and WIFI transmission.
-
Digital transmission uses unidirectional image data transmission, similar to the data transmission form of a high-altitude TV broadcast tower, effectively solving the problem of “real-time” wireless image transmission and greatly increasing image transmission distance. Currently, mainstream aerial drones use digital transmission.
-
WIFI transmission is actually a type of digital transmission based on the WIFI communication protocol for real-time image transmission. Its advantages include mature technology and low cost, widely used, but it comes with high latency, poor anti-interference, and limited range. Most low-end aerial drones and toy drones use WIFI transmission.
Battery Life
The battery life of a drone determines the duration of the aerial experience. Currently, high-end aerial drones generally have a battery life of about 30-50 minutes, while low-end or toy-grade drones usually last around 10 minutes. Therefore, it is recommended to bring an extra battery when going out for aerial shooting to enhance the flying experience.
Others
In addition to the basic hardware considerations mentioned above, factors such as portability, waterproofing, and intelligence can also be considered based on personal needs.
Of course, the most important thing is to consider your budget and choose the most cost-effective and suitable product within your price range.
Once you buy a drone, make sure not to fly it illegally. It is advisable to obtain a pilot’s license to avoid unnecessary trouble and legal risks~ That concludes today’s content.
