BarcodeDetector()

CV_WRAP cv::barcode::BarcodeDetector::BarcodeDetector	(	const std::string &	prototxt_path = "",
		const std::string &	model_path = ""
	)

Initialize the BarcodeDetector.

引数

prototxt_path	prototxt file path for the super resolution model
model_path	model file path for the super resolution model

関数詳解

decode()

CV_WRAP bool cv::barcode::BarcodeDetector::decode	(	InputArray	img,
		InputArray	points,
		CV_OUT std::vector< std::string > &	decoded_info,
		CV_OUT std::vector< BarcodeType > &	decoded_type
	)		const

Decodes barcode in image once it's found by the detect() method.

引数

img	grayscale or color (BGR) image containing bar code.
points	vector of rotated rectangle vertices found by detect() method (or some other algorithm). For N detected barcodes, the dimensions of this array should be [N][4]. Order of four points in vector<Point2f> is bottomLeft, topLeft, topRight, bottomRight.
decoded_info	UTF8-encoded output vector of string or empty vector of string if the codes cannot be decoded.
decoded_type	vector of BarcodeType, specifies the type of these barcodes

detect()

CV_WRAP bool cv::barcode::BarcodeDetector::detect	(	InputArray	img,
		OutputArray	points
	)		const

Detects Barcode in image and returns the rectangle(s) containing the code.

引数

img	grayscale or color (BGR) image containing (or not) Barcode.
points	Output vector of vector of vertices of the minimum-area rotated rectangle containing the codes. For N detected barcodes, the dimensions of this array should be [N][4]. Order of four points in vector< Point2f> is bottomLeft, topLeft, topRight, bottomRight.

detectAndDecode()

CV_WRAP bool cv::barcode::BarcodeDetector::detectAndDecode	(	InputArray	img,
		CV_OUT std::vector< std::string > &	decoded_info,
		CV_OUT std::vector< BarcodeType > &	decoded_type,
		OutputArray	points = noArray()
	)		const

Both detects and decodes barcode

引数

img	grayscale or color (BGR) image containing barcode.
decoded_info	UTF8-encoded output vector of string(s) or empty vector of string if the codes cannot be decoded.
decoded_type	vector of BarcodeType, specifies the type of these barcodes
points	optional output vector of vertices of the found barcode rectangle. Will be empty if not found.
