Struct opencv::wechat_qrcode::WeChatQRCode

pub struct WeChatQRCode { /* fields omitted */ }

• 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.

Implementations

impl WeChatQRCode

pub fn new(
    detector_prototxt_path: &str,
    detector_caffe_model_path: &str,
    super_resolution_prototxt_path: &str,
    super_resolution_caffe_model_path: &str
) -> Result<WeChatQRCode>

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

C++ default parameters

• detector_prototxt_path: “”
• detector_caffe_model_path: “”
• super_resolution_prototxt_path: “”
• super_resolution_caffe_model_path: “”

Trait Implementations

impl Boxed for WeChatQRCode

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl Drop for WeChatQRCode

fn drop(&mut self)

Executes the destructor for this type.

impl WeChatQRCodeTrait for WeChatQRCode

fn as_raw_mut_WeChatQRCode(&mut self) -> *mut c_void

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

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