I used to think like that, too. Then I read about digital filters in Software Defined Radios that can filter high frequencies used in radios. The Fourier filters give frequency and phase angle. The phase angle could be used for tracking. The reason I jumped into this topic is I am learning about filtering to make a sound compass because I lost my sound direction when I went deaf in one ear.mjpcarbon wrote:Wouldnt a noisy environment affect this ?

you'd think , but you tell me when your in a city and everyone walking with a cell phone... or every house has cordless everything.. you'd think that is noisy too. Amazing the "tuning" that can be done as to keep everyone separated.

Re: How is this being done !!
Wasn't it stated in the FAQ section on the website that the camera has to remain stationary and if moved it had to re-synchronize with the tag?Also to note , no , the "pod" doesn't need to stay stationary(pod being what the camera attaches to /ground.
You can move it around as its working.Hence , you could potencially have this ground pod mounted to the hood of your car, have somethign "flying around" with the locator , ..you get the point;)

Re: How is this being done !!
hmmmm , no clue. i wouldn't "think" that..... hmmmm.
Well yeh , that would ruin it , . i Know with the "homebuilt" setup /FPV /rc antenna tracker , your "base" can move.No reason i can think of "why" it couldn't move.?Any ideas?

Re: How is this being done !!
Perhaps because this one doesn't actually work the way people on this thread have hypothesized it must work?
This company is being pretty careful not to give up their secret, but I don't know why you would go for an expensive camera that has to remain stationary so somebody can steal it while you're surfing over something you could have mounted on a boat or something if it really does work just as good.

Re: How is this being done !!
can' think of any other way it "can" work , it has to track somehow , its not infrared, cause that wouldn't work at distance in bright light.... would have to be awfully powerful infrared.
RSSI makes sense , and gps kinda makes sense, both though you'd be able to move the ground station.
Whats left?

Re: How is this being done !!
I guessed audio because I am researching it, but I have no clue. People read something into the word "pairing". How about the word "tag"? An RFID tag maybe??

Re: How is this being done !!
RFID tagging is an ID system that uses small radio frequency identification devices for identification and tracking purposes. An RFID tagging system includes the tag itself, a read/write device, and a host system application for data collection, processing, and transmission.
Which goes back to RSSI and freq. as i stated, like one of those things you put on an object to find it with your phone, or like your cars electronic door un-locker."
As far as i can tell, you don't need to lock position of this , the transmitter (the unit to be placed onto the object to track) isn't locking to any particular GPS coord that i see. also would mean , if its overcast day or indoors , that it wouldn't work(or work poorly). GPS wise that is.
Seems someones gonna have to buy this and disassemble it:P

Re: How is this being done !!
If both devices have GPS and are in some communication with each other, through Bluetooth or some sort of radio signal, they can relay their position to one-another. This way the camera always knows where the tag or tags are at all times. If you leave your camera stationary then you only have to broadcast in one direction, from the tag to the camera, the camera just has to point in the direction of the coordinates it is being told. If the tag has a GPS and a small transmitter and maybe an accelerometer and gyro, it can give the camera more information about where it is, what direction it's moving in and how fast it is moving in that direction.
I guess what I'm arguing is does the camera really have to be stationary? no, probably not. But they designed it this way to conserve power in the tag since it's smaller, giving it the simple job of broadcasting where it is and how fast it's moving without having to also calculate where it is in relation to a camera or several cameras and possibly a bunch of other tags makes it's job a bit easier.
Hey, we can buy pretty much everything we would need to make these right here.

Re: How is this being done !!
My thought is OpenCV , which will run on many of the more modern Linux boards (i.e Beaglebone Black, Raspberry Pi). In that case, I actually do not think it would be that hard to distinguish a person from an, even 'active' set scene. For me, the real 'caveat' here on both their site and description is the 'look at me' factor, or there is only one person in each scene. They are not promising to 'hunt you down in a crowd', so rather than GPS, I think it could be CV based.
I also could be wrong :)
Code: Select all

Re: How is this being done !!
ahhh yes!!!, DOH!.... Why i was thinking "gps/ haha out in space haha!!!!
Yes , a "local" gps..... itself too itself... nothing else involved:) Makes sense.
DIY , yep everything is here that i see.From the videos of it "in action" seems to have a "delay" a bit...Not sure if that's a "tunable" aspect or not , .(Adding its own drift to simulate a persons hand. Verses, mechanical / super locked "to target" tracking.
Either way , however they did it. Its a nice looking unit and with the pricetag.....Worth it.
Be fun to use and tinker with.
AND! Which ever way they did it almost doesn't matter anymore . Look how many different ways that it can be played with now!:)
!DIY for the win!

so i have a Stepper motor and a controller can i use a RPI to interface and control the stepper using python? im looking for a thread that could help me but cant find one

There's also this nice little bit of "Shut up and take my money" .. I think I might want one of these in the near future.
