Counting Groceries with Computer Vision: How Picnic Tracks Inventory Automatically
Sven Arends

In this talk, we'll share how we're using computer vision to automate stock counting, right on the conveyor belt. We'll discuss the challenges we've faced with the hardware, software, and GenAI components, and we'll also review our own benchmark results for the various state-of-the-art models. Finally, we'll cover the practical aspects of GenAI deployment, including prompt optimization, preventing LLM "yapping," and creating a robust feedback loop for continuous improvement.
