LibInvImaging

Library inventory imaging - pilot project

This repository contains code to generate and read DataMatrix shelf codes. The idea is to support a faster inventory process by taking pictures of shelves and automatically rename those pictures with the correct shelf identifier. Images are to be collected in a database to enable comparison of shelf content over time.

The project also explored various options for quick image capture.

• make_dtmx.py generates DataMatrix image files for a series of shelves. Example:

• parse_folder.py looks at jpeg images in the input folder and assumes a DataMatrix code is somewhere in the lower right corner of the image. Images are renamed to the shelf identifier code and moved to a specified target folder.

Install requirements

pip install -r requirements.txt

Installing the libDMTX library

libDMTX is required for generating and detecting DataMatrix codes.
