Learn how to set up your FPV OSD with Goggles
Now that we've seen how to sync FPV goggles to your quadcopter drone, you would want to see how to setup the OSD.
First Person View (FPV) gives you true pilot’s sight view while flying by installing a transmitter and video camera on your vehicle paired with either goggles or an LCD and receiver on the ground. An On-Screen Display (OSD) supports to maintain adjustment by providing aircraft tool overlay on your FPV monitor. MinimOSD “On-Screen Display” is a minute circuit board that drags telemetry data from your Pixhawk or APM autopilot and over-lays it on your First Person View monitor.
Recommended parts to adjust FPV OSD:
To set up an FPV system on your Plane/Copter outfitted vehicle you will require the following components:
- Small video camera: The type of cameras progresses daily. Nowadays, most of the cameras maintain resolutions of 600-1200 TVL (TV Lines) and have ample supply range limit (5-24V typically). The lens is accessible from wide-angle (<2.8mm) to ultra-narrow (>5mm). For mini-quads, normally wide-angle is applied, while for aircraft, the average field of view/focal lengths range from (2.8mm-3.6mm). A wide range is easily detected by exploring the internet for FPV Camera.
- 5.8 GHz 25mw to 200mw receiver/video transmitter pair: Again, supply voltage limits easily support 2s-4s Lipo batteries commonly used as vehicle power.
- OSD (On-Screen-Display): Many autopilots at present combine this function directly. If not, surface OSDs like MinimOSD can be utilised. However, being capable to see the battery state, flight data, etc. makes a much more pleasant flight!
- Segregate batteries for powering the above are seldom needed since most of them include the flight pack’s voltage vary from full to empty. In addition, you will require a monitor like the Black Pearl or goggles.
Turning on FPV goggles:
- Connect the four stub antennas, and verify that they are well compressed
- Power on the goggles with a 3S or 4S LiPo battery utilising the given cable
- Connect the goggles, and change IPD sliders at the base to assure a clear view
- If you need to record video in goggles, you have to insert a Micro SD card
- First power on the DJI FPV Goggles afore connecting it to your network by the provided USB-C cable.
- Download the proper version of DJI Assistant 2.
- Start DJI Assistant 2 and sign up with your DJI account.
- You can view the “DJI FPV goggles” symbol. If you don’t find it, reconnect the USB cable. It may take a few moments for the computer to connect the driver when you install it for the first time.
- Click the symbol, and you will be advised to activate your device. Confirm that you have a proper internet connection!
- You will have to activate each part separately, however the steps are the same. Repeat this process for the Air Unit and remote controller.
Goggle options to look for:
- A broad range of goggles that contains the “Dominator” and “Attitude” has been verified to work. A few models appear with a built-in receiver and transmitter that would substitute the 3DR video kits 5.8 GHz receiver/transmitter pair specified above.
- Low-cost 320x240 resolution goggles are not suggested because the higher resolution 640x480 or SVGA goggles give a much more satisfying flying experience.
