Hello We are doing a school project atm where we use a usb-webcam and a MyRio to detect some QR codes and make a drone fly. We would like to know instantly (or as fast as possible) when a QR code is detected, and what it says, so we are looking into the posibility of putting the QR code detection on the FPGA. I am still new to FPGA programming, so I am wondering if anybody have some examples/sample code I could look at. We have allready made a QR code detection program, but the VI's we use are not to find on the FPGA vi. Any help is much apreciated. Best regrads Marcus

Image processing on an FPGA needs to be a linear process. You can't manipulate 2D data very well on an FPGA. Most 2D barcodes require the entire barcode to be decoded as a unit. You might have luck locating the barcode, but I wouldn't expect it to be worth the effort. Spending a few msec on each barcode after it is acquired will work better on the RT operating system. I suspect it would be faster as well. FPGAs don't process data as fast as a standard CPU, so you would probably spend a lot of time implementing an FPGA algorithm only to find out the RT CPU can provide the results faster. Bruce
