class BarcodeDetection

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

Typical usage:

barcode_detector = edgeiq.BarcodeDetection()

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

for prediction in results.predictions:
    text.append("{}: {}".format(
                prediction.barcode_type, prediction.info))
localize_decode(image)

Localizes and decodes barcodes in an image.

Parameters

image (numpy array of image in BGR format) – The image to analyze.

Returns

BarcodeDetectionResults

localize(image)

Localize barcode(s) within an image.

Parameters

image (numpy array of image in BGR format) – The image to analyze.

Returns

numpy array – Boxes around localized barcodes

decode(image, boxes)

Decodes localized barcode(s).

Parameters
Returns

BarcodeDetectionResults

publish_analytics(results, tag=None)

Publish Barcode Detection results to the alwaysAI Analytics Service

Parameters

  • results (BarcodeDetectionResults) – The results to publish.

  • tag (JSON-serializable object) – Additional information to assist in querying and visualizations.
