Hi, I'm running the example /opencv-4.0.0/sample/cpp/qrcode.cpp to detect and decode QR code. It can work with QR Code version 1~5, it seems like run QR code version 6 will cause memory corruption:
The qr code example from below link (Example of a QR code) https://whatis.techtarget.com/definition/QR-code-quick-response-code
I traced the code it seem like the following line will stop the decoding processing and cause the memory corruption /opencv-4.0.0/modules/objdetect/src/qrcode.cpp straight = Mat(Size(version_size, version_size), CV_8UC1, Scalar(0));
Can someone explain me how to solve it ? Thanks
