Camera for crazyflie

Post by kuba2111 » Mon Jul 17, 2017 4:06 pm

Hi!

I am data scientist working mainly in python and I want to implement some computer vision to my crazyflie. The problem is that I dont have slight idea about electronics, physics etc. ( I dont know what Ghz is, how to solder cables etc. ) and I dont have any equipment except for laptop and crazyflie 2.0 (https://store.bitcraze.io/collections/b ... ker-bundle)
My question is whether without knowledge from electronics and equipment (like soldering iron) I will be able to mount camera to crazyflie :
https://www.hackster.io/fredg/crazyflie ... tup-d2fc25
I want video stream flowing into my ubuntu laptop. If I have crazyflie 2.0. and https://hobbyking.com/en_us/quanum-elit ... tore=en_us what should I buy in order to make it working? Some USB video receiver which will receive signal from camera and then I will transform this signal to graphics by some python library?

Sorry, for extremely newbie question.

Hi,
I have been buying a similar camera recently (https://www.teknikmagasinet.se/produkte ... ra-5-8-ghz) and it works pretty much out of the box! I actually wanted to make a new hackster project about it. It contains the required cable to power the camera using the Crazyflie battery (this will reduce the flight time, I have not tested how much yet, it could be more efficient to add a smaller battery for the camera, to be tested ....).

If you want to get the video feed in your computer you need a compatible FPV receiver and a digitizer to acquire the video. On the PC side it will look like any other USB camera/webcam and you should be able to use things like opencv.

I have not tested the USB digitizer part yet, if anyone have a reference of one that work on Linux I am very interested: the only one I have tried only worked on Windows ...

Thanks for answer. Could you tell, what video receiver and USB digitalizer are you using?

For the digitizer I have none that works for now and I am very interested if anyone passing by has a tip for one that works well on Linux (and Windows/Mac).

For the receiver, I have tested with this two: https://hobbyking.com/en_us/skyzone-fpv ... er-v2.html and https://hobbyking.com/en_us/skyzone-fpv ... ables.html. My understanding is that any 5.8GHz analog FPV receiver should be compatible, but I am no expert in fpv so double check.

Thanks. I am also waiting for anyone who will give us fully working and checked combo (camera + video receiver + usb digitizer)

I haven't tested them myself, but saw good reviews for the USB digitizers from LaserBGC: http://laserbgc.com/index.php

There is a ready-to-go USB digitizer that contains a video receiver, but it's currently out of stock.

Please note: for the "modular" versions of the USB digitizers, you will need to purchase the actual video receiver board (FatShark dominator compatible) separately.
