Required Methods

fn as_raw_BarcodeDetector(&self) -> *const c_void

Provided Methods

fn detect(
    &self,
    img: &dyn ToInputArray,
    points: &mut dyn ToOutputArray
) -> Result<bool>

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

Parameters

• 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.

fn decode(
    &self,
    img: &dyn ToInputArray,
    points: &dyn ToInputArray,
    decoded_info: &mut Vector<String>,
    decoded_type: &mut Vector<BarcodeType>
) -> Result<bool>

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

Parameters

• 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 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

fn detect_and_decode(
    &self,
    img: &dyn ToInputArray,
    decoded_info: &mut Vector<String>,
    decoded_type: &mut Vector<BarcodeType>,
    points: &mut dyn ToOutputArray
) -> Result<bool>

Both detects and decodes barcode

Parameters

• 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.

C++ default parameters

• points: noArray()
