§ decode()
Python: |
---|
| retval, straight_qrcode | = | cv.QRCodeDetector.decode( | img, points[, straight_qrcode] | ) |
Decodes QR code in image once it's found by the detect() method. Returns UTF8-encoded output string or empty string if the code cannot be decoded.
- Parameters
-
img | grayscale or color (BGR) image containing QR code. |
points | Quadrangle vertices found by detect() method (or some other algorithm). |
straight_qrcode | The optional output image containing rectified and binarized QR code |
§ detect()
Python: |
---|
| retval, points | = | cv.QRCodeDetector.detect( | img[, points] | ) |
Detects QR code in image and returns the quadrangle containing the code.
- Parameters
-
img | grayscale or color (BGR) image containing (or not) QR code. |
points | Output vector of vertices of the minimum-area quadrangle containing the code. |
§ detectAndDecode()
Python: |
---|
| retval, points, straight_qrcode | = | cv.QRCodeDetector.detectAndDecode( | img[, points[, straight_qrcode]] | ) |
Both detects and decodes QR code.
- Parameters
-
img | grayscale or color (BGR) image containing QR code. |
points | opiotnal output array of vertices of the found QR code quadrangle. Will be empty if not found. |
straight_qrcode | The optional output image containing rectified and binarized QR code |
§ setEpsX()
void cv::QRCodeDetector::setEpsX |
( |
double |
epsX | ) |
|
Python: |
---|
| None | = | cv.QRCodeDetector.setEpsX( | epsX | ) |
sets the epsilon used during the horizontal scan of QR code stop marker detection.
- Parameters
-
epsX | Epsilon neighborhood, which allows you to determine the horizontal pattern of the scheme 1:1:3:1:1 according to QR code standard. |
§ setEpsY()
void cv::QRCodeDetector::setEpsY |
( |
double |
epsY | ) |
|
Python: |
---|
| None | = | cv.QRCodeDetector.setEpsY( | epsY | ) |
sets the epsilon used during the vertical scan of QR code stop marker detection.
- Parameters
-
epsY | Epsilon neighborhood, which allows you to determine the vertical pattern of the scheme 1:1:3:1:1 according to QR code standard. |
