A SMART 3D CAMPUS NAVIGATION SYSTEM WITH AR INTEGRATION AND SECURE ACCESS

International Journal of Computer Science (IJCS) Published by SK Research Group of Companies (SKRGC)

Abstract

It can be difficult for new students, visitors, and event-goers to get around big college campuses. Conventional GPS-based systems do not help much, as they do not support indoor navigation, offline mapping, and secure access. This paper suggests NavMate, a Smart 3D Campus Navigation System that incorporates Augmented Reality (AR), 3D mapping, and QR-based secure authentication. The platform supports secure log- in via Student, Teacher ID QR codes or temporary visitor access, maintaining data privacy and usage control. In real time, directional arrows and markers are superimposed over the physical world through AR technology, offering interactive indoor and outdoor guidance. A graph-based path algorithm optimizes route planning between destinations, and interactive 3D campus map facilitates visualization of locations with zoom and rotation functions. NavMate is also offline-capable and has an event and exam hall finder to help with scheduling academic activities. Through the integration of accessibility, interactivity, and security, the system improves the experience of its users and helps in realizing a contemporary, smart campus setup
