Detailed Description

WeChat QRCode includes two CNN-based models: A object detection model and a super resolution model. Object detection model is applied to detect QRCode with the bounding box. super resolution model is applied to zoom in QRCode when it is small.

Constructor & Destructor Documentation

◆ WeChatQRCode()

cv::wechat_qrcode::WeChatQRCode::WeChatQRCode	(	const std::string &	detector_prototxt_path = `""`,
		const std::string &	detector_caffe_model_path = `""`,
		const std::string &	super_resolution_prototxt_path = `""`,
		const std::string &	super_resolution_caffe_model_path = `""`
	)

Python:
	cv.wechat_qrcode_WeChatQRCode(	[, detector_prototxt_path[, detector_caffe_model_path[, super_resolution_prototxt_path[, super_resolution_caffe_model_path]]]]	) ->	<wechat_qrcode_WeChatQRCode object>

Initialize the WeChatQRCode. It includes two models, which are packaged with caffe format. Therefore, there are prototxt and caffe models (In total, four paramenters).

Parameters

detector_prototxt_path	prototxt file path for the detector
detector_caffe_model_path	caffe model file path for the detector
super_resolution_prototxt_path	prototxt file path for the super resolution model
super_resolution_caffe_model_path	caffe file path for the super resolution model

◆ ~WeChatQRCode()

cv::wechat_qrcode::WeChatQRCode::~WeChatQRCode ( )

inline

Member Function Documentation

◆ detectAndDecode()

std::vector<std::string> cv::wechat_qrcode::WeChatQRCode::detectAndDecode	(	InputArray	img,
		OutputArrayOfArrays	points = `noArray()`
	)

Python:
	cv.wechat_qrcode_WeChatQRCode.detectAndDecode(	img[, points]	) ->	retval, points

Both detects and decodes QR code. To simplify the usage, there is a only API: detectAndDecode.

Parameters

img	supports grayscale or color (BGR) image.
points	optional output array of vertices of the found QR code quadrangle. Will be empty if not found.

Returns: list of decoded string.
