This system is a portable assistive device that uses a Jetson-based embedded platform with a ZED 2i stereo camera, GNSS, and ultrasonic sensors to provide real-time navigation for visually impaired students. It utilizes RTAB-CUDA and CUDA-optimized ORB-SLAM under ROS2 for depth estimation, mapping, and localization within campus environments, while sensor fusion supports obstacle detection, distance estimation, and safe path prediction. Navigation instructions are delivered through an audio module, enabling real-time verbal guidance, and the modular design ensures scalability and affordability for blind school applications.
