QRCodeDetection¶

class QRCodeDetectionPrediction(box, info)¶

A single prediction from QRCodeDetection.

property box¶

The bounding box around the detected QR Code.

Type: numpy array

property info¶

The extracted QR code information

Type: string

class QRCodeDetectionResults(predictions, image)¶

All the results of QR code detection from QRCodeDetection.

property predictions¶

The list of predictions.

Type: list of QRCodeDetectionPrediction

property image¶

The image the results were processed on.

Type: numpy array – The image in BGR format

markup_image()¶

Draw detected QR Code boxes on the image.

Returns: numpy array – The marked-up image

class QRCodeDetection¶

Locate, detect and decode the QR Code(s) within an image.

Typical usage:

qrcode_detector = edgeiq.QRCodeDetection()

<get image>
results = qrcode_detector.localize_decode(image)
image = results.markup_image()

for prediction in results.predictions:
    text.append(prediction.info)

localize_decode(image)¶

Localizes and decodes QR Codes in an image.

Parameters: image (numpy array of image in BGR format) – The image to analyze.
Returns: QRCodeDetectionResults

publish_analytics(results, tag=None)¶

Publish QR Code Detection results to the alwaysAI Analytics Service

Parameters

results (QRCodeDetectionResults) – The results to publish.
tag (JSON-serializable object) – Additional information to assist in querying and visualizations.
