Re: OpenCV hover-assist
Than you Marcus, I shall go down this path and try and do it "right". Although I must say your team has set a pretty lofty bar for right...(a little aviation humor to start your new year)...D

Re: OpenCV hover-assist
So, I've scanned most of the source, both client and flie, and have a (very!) vague idea about what's going on. I think that the input.py program would be a logical place to knit in my theoretical hover-assist, +/- the thrust in that loop. I'm thinking to keep my hands as far out of the existing cod...

Working off this: https://github.com/jessicaaustin/roboti ... tracker.py
She hooked a camera up to it, which should make for a decent tracker, at least until it crashes into my forehead seeking blue reflections...

OpenCV hover-assist
Still haven't destroyed our two CF 2.0's and hoping to snake in some hover assistance using OpenCV with a webcam. The blue LED make for good tracking (except when the lights bounce off my shiny forehead...). I've cobbled together some inline python code based on OpenCV examples, and I'm looking for ...

Re: Crazyflie Hover with SimpleCV
Any further on this? (SimpleCV looks to be so...simple!) Might this knit in with the cfclient nicely and stay in native python?

Re: Communication problems when running multiple Crazyflies
There's a Quality signal/display on the client that you might be able to plot. Normally there's a means to determine Bit Error Rate (or block errror rate) so you can try stuff and see if it helps. One thing to determine is: is this an uplink (computer to flie) or downlink problem. Or both. If your s...

Re: Communication problems when running multiple Crazyflies
I'm new to CF, but I do RF comms professionally, so maybe I can offer some minor assistance. Presume you're using 250 KB channels (not 1 or 2 MB)? There is an effect known as Intermodulation (IM) in which frequencies add and subtract from each other forming an algebraic mess (2A-B, etc.). Way too mu...

Re: Greetings from Sunny Miami
Thanks for that. I"ve been peering at those little cameras, and doubt they'll get much lighter in the immediate future. I'm wondering if there's any hope of doing it digital one day, and exploiting some of that Crazyradio bandwidth, perhaps for a reduce frame rate or some such. I guess the heav...

Re: Greetings from Sunny Miami
the Generic_OS_X mapping for the PS3 controller has R1 mapped to full throttle for some reason. The way i hold the controller it is very easy to accidentally press that button, sending the CrazyFlie soaring! Took me a couple of flights before i realized what was going on...Might be completely unrel...
