Vision Recognition Technology in Smart Fridges

Vision Recognition Technology in Smart Fridges

Computer vision, also known as dynamic visual recognition, is a type of image recognition commonly used in smart retail fridges. It involves cameras to capture images that are analyzed by AI and computer vision algorithms to identify products. This allows the fridge to automatically scan items taken by customers and tally purchases.

Image recognition is divided into static and dynamic visual recognition

Limitations of Static Image Recognition

Static image recognition works similarly to RFID, comparing images before and after the fridge door opens to detect missing items. But it has limitations like low restocking and operational efficiency. Building image models for the many retail SKUs is costly. So it's not ideal for retail settings.

Benefits of Dynamic Image Recognition

Dynamic image recognition differs by tracking shopper trajectories and recognizing purchasing behavior and products taken. These smart fridges can have stacked items and broad product categories. This enables greater restocking efficiency, higher sales per fridge, and flexibility.

Combining Technologies for Enhanced Recognition

No single technology is perfect, so composite recognition combines multiple methods to complement each other. Examples are static image + weight sensors, RFID + static imaging, dynamic imaging + weight sensors, and dynamic + static imaging + weight sensors. The strengths and weaknesses balance out for more robust recognition.

Smarter Fridges Powering Unattended Retail

While the technology enables unattended retail, that is not the end goal. Intelligent fridges will connect people, goods and places in new ways to create more retail value.
