Currently, I am in the process of creating a web application for detecting QrCodes using Opencv.Js. Everything is working smoothly with functions like findcountour and GaussianBlur, but it appears that cv.QRCodeDetector() is not available.
let detector = cv.QRCodeDetector()
This results in:
The error message: 'cv.QRCodeDetector is not a function'
The current version I have installed (4.5.2) already includes it. You may need to update your OpenCV version.
It transformed into a constructor, therefore include the keyword "new" in this manner
const decoder = new cv.QRCodeDetector();
