Receiving FPV data on PC
Posted: Wed May 01, 2013 9:57 am
Hi there,
Once my drone arrives I'm hoping to use it for FPV flight, like Bitcraze did here:
http://www.bitcraze.se/2013/03/first-fpv-flight-test/
I'm wanting to receive video and process it directly on a computer running Linux.
I've got a couple of questions about that:
1. I like the camera that was used in the flight test (http://www.fpvhobby.com/96-8ghz-micro-combo-set.html). I'm not sure if I understand the site correctly - it lists a 5.8gHz 10mw Tx, apparently for transmitting, and a 5.8gHz 8 ch. Rx, apprently for receiving, but I don#t see where the video output would go. Is there a good way of connecting that to a computer, e.g. via USB, or would I have to buy an extra receiver?
2. On the same site there are lots of receivers(e.g. http://www.fpvhobby.com/33-4ghz-8-ch-a-v-receiver.html), but they all use A/V outputs. Would it be better to shop around for another receiver that outputs a video stream directly that I can work with on my computer, or would you recommend getting on of those EasyCAP adapters?
3. Does anyone have experience working with such video receiving systems on Linux? I imagine that drivers could be pretty difficult to work with, but I have no experience at all in the area so I couldn't say. On the Internet I haven't found that much yet.
4. In the FPV flight test, the camera was powered by the VCOM foltage on the Crazyflie. Is there any kind of instruction set available for connecting those, or can I just solder a wire between the VCOM and the power input for the microcamera?
I'm sure these are pretty basic questions, but my experience is more with software, and not at all with hardware. Thanks for the help!
