Qr Code Recognition Module Has Bugs Issue 3519 Opencv Opencv @zsffuture could you attach your test image and reproducer code or sample name you use with its parameters. @zsffuture i transfered the issue to opencv contrib. the module is stored there. I need to extract a password from the qr code. i've tried using a qr code reader on my phone and i can get the password so i can confirm that there is no issue with the qr code itself.
Opencv Qr Code As a part of my application, to decode qr codes, i am using cv2.qrcodedetector () class and detectanddecode () function. python version is 3.7.7, opencv version 4.2.0, platform is arm64. 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:. Tl;dr: qrcode detection crashes my system and flood ram swap and some unknown memory. setup: ubuntu 20.04 running on virtualbox with 2gb ram, 2 processors, 10gb disk. background: i am trying to build a gui app (using tkinter) for reading qr codes (qrcode.detectanddecode) from a webcamera (opencv). I’m working on an application that needs to decode qr codes found within photos. i have found that even if i use methods to isolate likely sub areas in the images that contain the qr code, qrcodedetector still doesn’t work very reliably.

The qr code was detected but the decoded text is empty. i opened a thread on stackoverflow and other users have confirmed having the same issue with this image. I wrote a simple qrcode detection and decode code with opencv. but the problem i'm facing is that the qr code gets detected but can't be decoded with the following image (see bottom). the code i wrote looks like this: cv::mat src = imread("scaled "); if(src.empty()) cout << "can not open " << "picture" << endl; return 1;. Particular images are hanging on the call to detect and decode for the qr code detector. they run for about 10 minutes and then provide the error: cv2.error: unknown c exception from opencv code . One of the problems seems to be that the detectanddecodecurved function is trying to flood fill at a point outside the image. now, why is this happening we don't know because you did not provide a mre along with your input image.
