Which codes does QR Code Reader read?

QR codes, the 2D symbology with square finder patterns in three corners. They carry long payloads such as a URL or a serial number.

Does QR Code Reader need a template, training or configuration?

No. You give the reader the address of an image and run it. Every code in the image is reported, not just one – each with its decoded text, centre, outline and score.

Does QR Code Reader run on ctrlX OS and on a PC?

Yes. On ctrlX OS (ctrlX CORE or ctrlX IPC) it uses the ctrlX Data Layer; on a PC with Windows 11 or Ubuntu 24.04 it uses LumiScan Keryx. Node addresses, types and behaviour are the same on both, so a program written against one works against the other. On a PC, a PLC controls it via OPC UA.

Where does the app get its images from?

It does not talk to a camera itself. It reads the image node of another app on the same device, normally LumiScan Cam Driver for GenICam cameras. Supported pixel formats are Mono8, Mono12, RGB8, RGB12, BGR8, BGR12 and the common Bayer 8/12-bit formats.

Can we see the codes that were read?

Yes. LumiScan Cockpit draws every code with its text on the image – in the browser on ctrlX OS or in its own window on a PC.

LumiScan QR Code Reader

Reads every QR code in the camera image – content and position, no template or training.

LumiScan QR Code Reader finds every QR code in a camera image and reports what each one says and where it is, with no limit of one code per run. QR codes carry long payloads such as a URL or a serial number, which makes them a common choice for identification and traceability with machine vision.

The reader needs no template, training or configuration: give it the address of an image and run it. Your PLC receives the decoded content and position of every code, on ctrlX OS or on a Windows or Ubuntu PC.
