AB - Obstacle detection in blind spots has emerged as a critical challenge due to the increasing adoption of Automated Guided Vehicle (AGV) and Autonomous Mobile Robot (AMR) systems in modern industrial environments. While conventional ultrasonic and single-bounce LiDAR sensors exhibit limitations in complex environments, Two-Bounce LiDAR offers higher detection precision but faces challenges such as high cost and limited diversity in training data. To address these challenge, this study proposes a framework that combines Two-Bounce LiDAR with Digital Twin simulation to generate synthetic data under various scenarios. Object detection models trained with this data achieved an average detection accuracy of 92.5% in environments including blind spots, with an average improvement of 14.67 percentage points in accuracy and 15.69 points in F1-score compared to models trained only on normal-environment data. These findings demonstrate that the proposed framework effectively overcomes data collection limitations and significantly enhances the safety and reliability of AGV and AMR operations.
