Fpv/osd

[AUsome]

I'm having trouble distinguishing between FPV and OSD and how these overlap or differ. If FPV is first person view/video and OSD is onscreen display, I am having trouble separating the two issues. For FPV, don't you have to have OSD (or a headset)? Or is OSD more than just showing you what the FPV is sending from the copter?

If FPV uses something like Gopro for its "eyes", does the Gopro lose the ability to record? Or are you simply seeing the same thing that the gopro sees.

Can FPV use a separate camera for its "eyes" to let the Gopro operate independently?

If FPV is sending back video, isn't that what the OSD is for...what else might the OSD be used for?

Sorry if this is very basic but I've spent 3 days really reading on this, but can't get my head around these two concepts.

TIA.

Silly questions are welcome! We all have them.

They are independent from each other. OSD is a graphical overlay of figures. Usually distance etc. Google glass displays writing on the lens (OSD) and your eyes are the FPV. FPV is video and the OSD is a HUD.

Does that even make sense?

Not sure if that last description was basic enough. FPV is first person view. FPV is not a physical thing, but requires special equipment to fly FPV. To fly FPV, you set up a camera on your aircraft and send the video feed through an on board transmitter to the ground. You, as the pilot, receive the transmission via a VRx (video Receiver). You can view the live video feed on goggles or a monitor. You can then fly the craft via what you see on the monitor or in the goggles. This is the basics of FPV and requires the camera, a Vtx (video transmitter), a VRx (video receiver), and a monitor. All of this is considered the FPV gear. (you can use a gopro to fly with, but you can also use a second small FPV camera if you have the gopro recording video on a stabilized camera mount (gimbal) which will mess up your ability to fly the craft via the gopro becasue it does not offer the orientation of the flying craft).

Aside from the FPV equipment, you can add OSD (on screen display). Which , as mentioned above, is just an overlay of information on the video feed that tells the pilot usefull information about what the aircraft is doing. Some OSD offers a glass cockpit type display with artificial horizon, speed, distance from home, compass, altitude, battery info, etc. Some OSD systems offer different info. OSD is hjighly suggested to give important information about the flight. It will get you home when you get lost in the sky, because everything looks different up there.

Be sure to use a spotter when learning FPV flying and go out into the middle of nowhere so you don't hurt anyone. Hope that helps.

Here are some usefull links. Most sell the equipment needed.A quick search brings up a couple basic videos.

I don;t know much about these sites, but they all offer basic info. I do use eagle tree, but also have built in OSD on my Hoverfly Pro.

Thanks for the info and the sites. Very helpful and I'm much more knowledgeable than before, but still a lot to digest.

Can FPV use a separate camera for its "eyes" to let the Gopro operate independently? Yes, probably a prefeed method is to use a second camera.

If FPV is sending back video, isn't that what the OSD is for...what else might the OSD be used for? The camera and video transmitter is sending back the video so you can fly FPV. The OSD is the add-on layer of information you can integrate as an option to get flight stats. OSD is not what the camera is seeing.

It is not too complicated once you start reviewing what equipment is needed.
