Many Beginner’s cabe preguntar should I buy FPV glasses in the beginning?

I wants to tell you is: Not necessarily! Beginner can start from the screen and progress to glasses。You can also start flying from a third perspective.

Because the first angle of view is played through the aircraft, you can use the screen or the third angle of flight in the early stage. After that, if you don’t wear FPV glasses to play, you will lose the joy of fpv drone.

Let's get back to the topic, what exactly is FPV glasses?

 

FPV glasses introduction

 

It is to provide flying friends with an immersive flight experience and make them feel like they are on an airplane.

 

That's why it's called FPV first person perspective.

 

The signal transmission path of image transmission is: image transmission transmitting module on the aircraft> image transmission transmitting antenna> image transmission receiving module> glasses body.

 

Glasses body

 

It is responsible for displaying the signals from the aircraft, that is, displaying the signals received by the receiving module on a small screen in front of your eyes.

 

Secondly, it is responsible for adjusting display effects, such as brightness, contrast, and color.

 

5.8G signal receiving module + antenna

 

It is a key component of the image transmission receiving end.Some glasses will come with them, and some will be bought separately.

 

Image transmission antenna

 

One is a mushroom antenna, which is round and mainly receives surround signals. That is to say, the plane can basically receive the image transmission signal. (The worst signal is in the airspace above the mushroom antenna)

 

One is a flat-panel antenna, which mainly receives the image transmission signals in the airspace facing the direction of the flat plate (the worst part of the signal is the airspace in the direction of the non-front-facing plate).

 

 

The separate image transmission receiving module uses two kinds of antennas at the same time, to cover the airspace as much as possible. So generally better glasses use two antennas.

In this way, the receiving module will automatically select and switch between two antennas with better quality signal sources at any time.

There is a small Tips: Spend money on the image transmission receiving module! !!

 

 

FPV glasses have one or two screens (depending on the type), which can display the real-time video of the aircraft during flight. Wearing glasses is easier to avoid obstacles than the third-view operation.

 

 

FPV glasses are not considered VR glasses because they do not have the immersive feel of VR glasses.

 

 

In addition, the FPV glasses are considered to be in the crossing machine, so there is no need to update and replace so diligently.

 

A pair of glasses can be used for a long time, which is a very durable set.

 

Picture quality and field of view of FPV glasses

 

Beginner‘s may have played with a friend's FPV glasses, saying that the quality of the glasses is so unclear.

 

Snowflake screen, spend thousands of yuan to buy a snowflake screen! !! Nothing looks like high-end goods!

 

In fact, in order to pursue speed, the ride-through machine abandoned the image quality. Due to the current FPV camera resolution and the limitation of the 5.8Ghz image transmission antenna, we may not be able to obtain high-definition image quality.

 

This is why everyone should hang GoPro or buy a card to record. If you do not do this, you will not be able to shoot high-definition video.

 

In addition, the video images displayed by the glasses have two common aspect ratios, 16: 9 and 4: 3.

 

 

Image distortion occurs when you use mismatched aspect ratios on FPV cameras and glasses.

When using with 16: 9 glasses and 4: 3 camera, the image will be stretched;

 

When using a 16: 9 camera and 4: 3 glasses, the image is squashed.

 

In terms of the field of view of FPV glasses, for example, when using 35-degree FOV in FPV goggles, the screen edge makes a 35-degree angle with the center of the eye. The larger the FOV, the more immersive the image.

 

 

But when the FOV becomes too large, it can be counterproductive. The image may be too large and you need to open your eyes more to focus on different parts of the screen.

 

 

If the 4: 3 ratio glasses, and 16: 9 widescreen ratio glasses, have the same FOV.

 

This is amazing, with a 4: 3 screen, it will also look bigger.

 

FPV glasses interpupillary distance adjustment

 

IPD refers to measuring the distance between the pupil centers of two eyes。

 

 

Generally, the glasses have an interpupillary distance adjustment. When the lever is toggled, the lenses in the glasses are also moving. This is a very user-friendly function.

 

Myopia friends may ask, can I wear these glasses?

 

Definitely!

 

 

Usually buying glasses will come with a separate myopia lens, you can install the lens to the lens position in the glasses.

 

However, some people say that such myopia lenses are not so accurate and will have a little impact.

 

You can also wear your own contact lenses, or you can find an owner who wears the glasses and specializes in a myopia lens.

 

 

Other characteristics of FPV glasses

 

FPV glasses may have modules for external video receivers and even built-in video receivers. The receiver module is designed for different purposes, such as remote 1.2Ghz support, diversity and different 5.8Ghz channel support, etc.

 

 

Built-in DVR

 

DVR stands for Digital Video Recorder and has DVR to record flight video on Micro SD card.

 

HDMI input

 

Allows you to connect the glasses as a monitor to a computer for watching movies or practicing with an FPV simulator; you can use it for HD FPV systems, such as Connex Prosight!

 

3D support

 

Allows you to use a 3D FPV camera / transmitter system

 

Audio output

 

Some people like to fly with audio. Audio allows you to connect more with the drone. Many glasses can provide this function through the headphone jack on the side.

 

 

Anti-fog fan

 

When your glasses are foggy in a dark and humid place, many glasses are equipped with a fan to remove the fog.

 

Glasses appearance color

 

Colors are mainly personal preferences.

 

FPV glasses cost-effective

 

As many people have said, the fat shark's glasses can be regarded as the "Apple" in the FPV glasses industry.

Low cost performance and high premium.

However, the fat shark looks outrageous and is suitable for the long and thin face of Europeans and Americans. Many domestic and foreign pilots are using it.

 

SkyZone is quite cost-effective. The 02X that comes out, the price / performance ratio is between

It's between FPV blinders and SkyZone 03.

However, it will give you a feeling that you always feel worse.

 

For flying friends with limited budget, FPV eye mask is the first choice.

 

An FPV eye mask is only a few hundred dollars, which is very friendly to flying friends with limited budgets.

 

emmm ...

Anyway, the glasses that pass through the machine are so chosen!
