Can anyone help me with scanning of QR Code.I have a quadcopter, i need to know the procedure and the equipments required to do so.

can you elaborate on what you want to do ?

it seems like you want to scan QR codes using a quadcopter ? quite intriguing !

what is the scenario ?

I have a F450 frame,with a Naza M lite flight controller,A2212 @1400kv motors,with a Naza GPS mounted.I want to scan a QR Code.The scenerios is such that a QR Code will be given and we have to scsn that code and we will have to drop the 50gm weight in the box of the same number as scanned by the qr Code.I just want to know.....that...how to scan and the camera needed to detect qr code.Image should be clear.

the easy way would be take a shot of the qr code and send to your fpv monitor where
you scan using your mobile phone.
or...
if you want the drone to do it autonomously - then use a raspberry pi zero with camera and python
to scan and identify the box number ,
get the gps coordinates of the location of the box
generate a lua script containing the coordinates and feed it to the flight controller running (for eg)inav

not saying that this will work - but just to give you a line of thinking.

thanks for ur help.
