Constant methods for crate::objdetect::BarcodeDetector

Required Methods§

Source

fn as_raw_BarcodeDetector(&self) -> *const c_void

Provided Methods§

Source

fn decode_with_type( &self, img: &impl ToInputArray, points: &impl ToInputArray, decoded_info: &mut Vector<String>, decoded_type: &mut Vector<String>, ) -> 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 strings, specifies the type of these barcodes

§Returns

true if at least one valid barcode have been found

Source

fn detect_and_decode_with_type( &self, img: &impl ToInputArray, decoded_info: &mut Vector<String>, decoded_type: &mut Vector<String>, points: &mut impl 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 strings, specifies the type of these barcodes
points: optional output vector of vertices of the found barcode rectangle. Will be empty if not found.

§Returns

true if at least one valid barcode have been found

§C++ default parameters

points: noArray()

Source

fn detect_and_decode_with_type_def( &self, img: &impl ToInputArray, decoded_info: &mut Vector<String>, decoded_type: &mut Vector<String>, ) -> 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 strings, specifies the type of these barcodes
points: optional output vector of vertices of the found barcode rectangle. Will be empty if not found.
