QR Code Detection¶
Class: QRCodeDetectorBlockV1
Source: inference.core.workflows.core_steps.models.third_party.qr_code_detection.v1.QRCodeDetectorBlockV1
Detect the location of a QR code.
This block is useful for manufacturing and consumer packaged goods projects where you need to detect a QR code region in an image. You can then apply Crop block to isolate each QR code then apply further processing (i.e. read a QR code with a custom block).
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/qr_code_detector@v1to add the block as
as step in your workflow.

The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
