- Abstract
- This paper presents a system designed for a quadruped robot that assists visually impaired individuals by analyzing road conditions and detecting drivable areas. The system integrates 3D point cloud data from Lidar with 2D semantic segmentation from RGB cameras, enabling a comprehensive understanding of the environment through a 3D-2D data fusion approach. By evaluating critical road properties such as flatness, material uniformity, slope, and vertical clearance, the system ensures safe and efficient navigation in complex terrains. To enhance depth perception, we incorporate depth completion techniques, allowing for real-time road condition assessment. The fusion of Lidar and RGB data creates accurate drivable area maps, enabling the robot to make informed decisions about path planning and obstacle avoidance. The proposed system is validated through real-world experiments, demonstrating its effectiveness in assisting visually impaired users by providing reliable navigation across diverse environments. The contributions of this work include the development of a robust road condition analysis module and the fusion of 3D-2D data for enhanced semantic segmentation, advancing the capabilities of assistive robotic systems for visually impaired navigation.
