This research work presents the design and implementation of an advanced indoor navigation system tailored for college campus (Xavier Institute of Engineering), leveraging LiDAR sensors and QR code technology for accurate location mapping. The system integrates LiDAR sensors to create high-resolution 3D maps of indoor environments, providing detailed spatial information. QR codes are strategically placed throughout the campus, acting as reference points for precise localization. Users' smartphones scan these QR codes and collect real-time LiDAR data, allowing the system to properly pinpoint their location. The proposed indoor navigation application offers students, faculty, and visitors an intuitive and efficient way to navigate complex college buildings. The LiDAR-based mapping ensures precise indoor positioning, while QR codes serve as reliable landmarks for seamless orientation. The system's user-friendly interface provides step-by-step directions, optimizing routes based on real-time data, and enhancing the overall user experience. The integration of LiDAR technology and QR codes addresses the limitations of conventional indoor navigation systems, offering a scalable and adaptable solution for educational institutions. The implementation demonstrates the potential of this hybrid approach in transforming indoor navigation experiences, making it an invaluable tool for enhancing campus accessibility, improving way finding efficiency, and ensuring a positive user experience.
