Using deep learning techniques for automated inspections

Back Apply now

Products manufactured by Prodrive Technologies range from smart thermostats and automotive wallboxes to large compute cabinets and gradient amplifiers. To ensure high-quality production, all these products have a final, visual inspection step where each product is inspected before it is packed and shipped to customers. Inspections including presence and anomaly detection are automated using the Keras and Tensorflow deep learning libraries where the classification and autoencoders models are developed and trained in-house. To improve the factory efficiency even more, these techniques will also be applied to factory data such as cycle times and process parameters for the purpose of diagnostics and predictive analysis.

At Prodrive Technologies I work as a software architect on the manufacturing automation of the factory, particularly the AI and vision solutions that provide the intelligence. What I find a big advantage of working here is that I have a big say in defining on what I want to work on. Currently, I do not only work on the implementation of software and algorithms but also have a more leading role in making architectural design choices and reviewing the work of other engineers.

When I start my day, I typically check if there is any review work for me to do. Reviewing each other’s work is very important so we can use the lessons learned, do not invent the wheel again and it also results in having everything documented as a bonus. I get a kick out of helping colleagues with their software, calibration, qualification and vision challenges and as a result often get quite a few calls every day. I will not get bored easily!

I can also spend some time on my own work which currently involves improving camera calibration algorithms. It uses ChArUco patterns that, without going into too many technical details, result in having a better distribution of calibration points and in turn gives a more accurate camera calibration. It is quite important to get this right as all future camera setups used for inspections and localization of components depend on the accuracy of this calibration.

Finally, as an architect I am working on a roadmap to determine the future of deep learning and machine vision at Prodrive Technologies. Visual inspection processes that are currently being automated are component presence detection, cable insertion and anomaly detection for product damage. I setup requirements for a generic machine learning framework and its applications so we can leverage machine learning technologies in multiple processes. This is a big motivator for me as I can really contribute to how the company applies vision and machine learning techniques that will play a large role the fully autonomous lights-out factory.
