Introduction to optical labels and barcodes

As we conclude this introductory and interactive course on how to read and write machine-readable optical labels with Python, it’s time to reflect on the knowledge and skills we have acquired.

We embarked on this journey with an introduction to the world of machine-readable optical labels, a technology that has become ubiquitous in our daily lives. This technology can be found anywhere from product labeling to patient identification, robot positioning, and even augmented reality.

We learned about the different types of labels, including linear barcodes, 2D barcodes like QR codes and Data Matrix codes, and fiduciary markers such as ArUco markers and AprilTags.

Our exploration of barcodes started with understanding the basics of 1D and 2D barcodes. We learned about their structure, how they encode information, and their various applications. This theoretical understanding was then put into practice as we delved into Python programming to write and read these barcodes.

We learned how to generate various types of barcodes and then read them back, a skill that has wide-ranging applications in many industries.
