Barcode scanning information

[[Ti...]]

Someone mentioned barcode scanning today in a meeting.  Is there information on this somewhere or a python function/script to scan something that I can test out in the future?

Hallo Tim Jones,

das Thema interessiert mich auch sehr, weil wir QR Code scannen sollen um unter anderem die Position auszugeben.

Hello,

You can use the built-in function to use the barcode to select the templates (works with KIOSK), or...you can use Python to take a picture (ex. from measurement) and read the position of qr/barcodes (Personally, I use the zxing library.).

Code example:

import gom
from PIL import Image, ImageDraw, ImageEnhance
import zxingcpp
import numpy as np

gom.interactive.automation.measure_at_selected_positions (measurements=[gom.app.project.measurement_series['Scan 1'].measurements['M1']])
mes_image = gom.app.project.measurement_series['Scan 1'].measurements['M1'].images['left camera'].data.rgb
data = np.array (mes_image[0])
result = zxingcpp.read_barcodes(data)
for code in result:
	print(code.text + ' ' +str(code.position))

I don't quite understand what you are saying. Are you saying that you personally take a picture of your part or scanning area and there is a QR code in there where you capture the barcode?

 

If we go to barcodes we will be scanning a label on a bag. So I think we would want to use the built-in funciton. 

 

My question is where is the built-in function, I don't see it anywhere?

 

Thanks

I guess I'm asking how to set up the functionality of a hand held scanner with python. I have the understanding of how to pull the embedded data from a qr code, but I'm more concerned with how to initialize the hand held scanner and if I should use anything inside GOM to do this or do it with simply python modules/libraries.

Well, I noticed that I was thinking about something else 😉

 

"Built-in" function:

You can configure  Kiosk Interface to read barcodes with barcodes scanner, but this is limited to loading templates (by value from barcode).

I think it only works with ScanBox, and hand held scanner require another way.

 

Python-way:

Rather, all ATOS scanners allows to initialise and acquire images from measurements via a script.
