FPV is the abbreviation of English first-person perspective, that is, "the main perspective of the first person". It is a new game based on the remote control aviation model or the vehicle model with wireless camera feedback equipment, and watch the screen control model on the ground.
The remote control model is generally controlled by the operator holding the remote control and watching the remote control model control its posture to complete various actions. In recent years, with the miniaturization of electronic equipment, we have the opportunity to install wireless video transmission equipment on the model with very limited volume and load, and realize the way of manipulating the model from the first perspective.
What you can achieve is that you can control your model plane or racing car to soar in the sky and on the ground from the driver's perspective without worrying about any risks. Although this is interesting, it is not a new idea, because it has been used in real high-tech fields, such as drones and computer-guided missiles.
Brief introduction of FPV common equipment:
1, display
That is, the display that receives the video through image transmission and displays it on the ground monitor is used to check the angle of view of the aircraft on the ground.
2. Remote control
That is, control the running track of the carrier and control the camera to take pictures and photographs.
3. Yuntai
A photographic or photographic connection device suitable for aerial photography. That is, a camera or device in which the camera is connected to a tripod.
4. Image transmission
Image transmission is divided into 1.2GHz, 2.4GHz and 5.8GHz according to different transmission frequencies. Because the frequency of 2.4G is the same as the remote control frequency, it may cause interference, so it is not recommended to use it on FPV. Image transmission is divided into sender and receiver. The transmitter is installed in the loader, and the information in the transmitter is sent to the ground receiver through the antenna and displayed on the screen after conversion. The transmitter power directly affects the transmission distance, and there are three factors that affect the distance: transmitter power, antenna gain and receiver sensitivity.
