How Lenta Tech Searched for Price Tags on Video from a Moving Robot: Results of the Video Analytics Hackathon

The Lenta Tech team (IT brand of the Lenta Group) shared their experience of conducting a hackathon on recognizing price tags from video captured by a moving robot. The article describes the solution pipeline: from detecting price tags using YOLO to extracting data via OCR, QR codes, and a catalog. Key takeaways: quality is achieved not by a single model but by proper handling of frame sequences (tracking, selecting the best frame) and combining OCR, QR, and catalog.
