Abstract
En 中文
The issue of out-of-stock (OOS) represents a substantial challenge for retailers, often resulting in significant sales losses. To address this problem, this paper introduces an autonomous mobile robotic platform built on the Robot Operating System (ROS) framework, designed to accelerate the restocking process in supermarkets. The platform autonomously detects empty shelves and notifies human operators, streamlining inventory management. Equipped with advanced navigation capabilities, the proposed system employs a deep learningbased, two-stage architecture that identifies shelving areas and subsequently detects empty shelves. To validate the performance of the proposed two-stage artificial vision algorithm, two datasets were used: the first comprises approximately 2000 images (900 of them collected by our team from three different supermarkets), while the second dataset consists of around 5600 manually annotated images extracted from videos recorded in a supermarket by the robotic platform itself. Additionally, in order to validate the entire robotic system, an extensive experimental evaluation was conducted in a supermarket during regular business hours. The results demonstrate that the proposed platform substantially outperforms human operators, identifying OOS items eight times faster than traditional human operator based methods. This advancement provides valuable assistance to supermarket staff, significantly enhancing operational efficiency.
