Release Notes: v1.1.0
First functioning release of LumiScan DMC Reader. Version 1.0.0 registered the application’s Data Layer nodes but returned a fixed placeholder result, so nothing below was usable before.
New
Data Matrix reading. execute searches a camera image for ECC 200 Data Matrix codes and reports
every one it finds. No reference picture and no training step: the only input that changes between
runs is which image to read.
A result per code, in output/results — the decoded text, the centre in image pixels, a confidence
score, and the corner points outlining the code. A run that found nothing publishes an empty array
rather than an error.
Any image source on the same ctrlX CORE. input/image-address names the image node to read, so the
reader follows whatever application publishes the picture. Mono, RGB, BGR and Bayer formats are
accepted at 8 and 12 bit, and Bayer images are converted to colour before the search.
Drawn results in LumiScan Cockpit, which lists the reader as a view named datamatrix-code and
draws a rectangle around each code, labelled with the decoded text and the score.
Worth knowing
A failed run leaves the previous result in place. This version publishes no status node and echoes
no identifier, so output/results alone does not distinguish a fresh read from a stale one. The
reason for a failure is written to the application log. An empty result is unambiguous: the image
was read and held no Data Matrix code.
input/parameter has no settings yet. Its DetectionParameters table is empty; the node exists so
that tuning can be added later without changing the node tree.
Every run searches the whole image. There is no region of interest, so run time scales with the image size.
