I have watched a lot of videos where a drone pilot flies their drone miles out from their location using First Person View (FPV) by viewing the return image from the camera on their phone or tablet.
So, my question is; has anyone actually performed a "scientific test" of the video delay on the smaller drones, such as the Mini 2, the SE, the Mini. I've put scientific test in quotes because I'm hoping for more than, "it sure looks instantaneous…"
I intend to perform my own test when the weather is better and the wife is available to help perform the test.
What I intend to do is position the wife in our car about 1,000 feet away, facing me, with her cell phone, I'll position myself looking towards the car with the drone directly in front of me also facing the car. I will be able to visually see the car and I'll be able to see the car in the projected image from the drone.
Using my cell phone camera positioned so that the camera is filming the FPV on the tablet with the car visible in the background, I will then tell my wife to turn on the headlights using the cell phone.
My cell phone with record the image of my car's headlights turning on and will also record the image of the headlight turning on in the FPV and record if there is any delay in the image of the lights turning on.
I will also perform the same test but with the drone flown up to the car so that when the test is performed again, I will be able to see if the distance makes any difference in delay.
Yeah, I know the transmission is at the speed of light, but the distance (with the slightly weaker signal) might make a difference as the drone and radio receiver processes the weaker signal…
When I do this, I will post the video on the web site for all, But in the meantime, is anyone aware of a similar test having been performed before?
