EQRCodeReader Class

Represents the QR code reader, that is a context for the detection and decoding of QR codes, represented by EQRCode objects.

Namespace: Euresys::Open_eVision_2_11

Methods

Decodes a QR code candidate, represented as a geometry (see EQRCodeGeometry).
Detects all QR code candidates in the search field, and returns them as a vector of geometries (EQRCodeGeometry objects).
Creates an EQRCodeReader object.
Sets the minimun cell polarity confidence threshold.
When the cell confidence is under the threshold, additional processing is attempted to improve the polarity detection.
Sets the detection method for finding QR codes. The method can be any combination of the EQRDetectionMethod enums.
This setting controls the trade-off between computation speed versus reliability of the detection methods.
Setting the trade-off will overwrite the current settings for EQRCodeScanPrecision and EQRDetectionMethod.
Activate or deactivate the filtering of unreliably decoded QR codes.
Foreground detection threshold. This parameter determines by how many grayscale-values a pixel should deviate from it's local background to be considered part of the foreground.
Maximum version of QR codes to be searched for.
QR code minimum isotropy.
Minimum pattern finder score that must be reached to consider that a finder pattern has been found.
Minimum version of QR codes to be searched for.
Sets the perspective mode from the EQRCodePerspectiveMode values.
Precision of the EQRCodeReader when scanning the search field.
QR code models to be searched for.
Detects and decodes all the QR codes in the search field. Returns them as EQRCode objects.
Sets the minimun cell polarity confidence threshold.
When the cell confidence is under the threshold, additional processing is attempted to improve the polarity detection.

Search field for the QR code reader.
