# An ARCore-Based Augmented Reality Campus Navigation System
## 7 Conclusions  
In order to solve the problem in which the route planning function in 2D/3D campus navigation systems in the market cannot simultaneously process indoor and outdoor localization information, this paper designs an ARCore-based augmented reality navigation system that integrates indoor and outdoor campus navigation. This design effectively solves the problems of the traditional campus navigation system, such as inflexible decision-making, inconvenient query and weak sense of architectural space. It also provides a technical solution for the intelligent management of university campus, which can better serve the construction of intelligent campus. Compared with the AR outdoor navigation system of Gaode, the proposed ARCore system can achieve more precise outdoor localization by deploying the visual inertia odometer on the mobile phone and realizes the AR function of 3D information and real scene; thus, this also enriches the user's interactive experience. Through four groups of student tests and system evaluations, experimental results show that the system could facilitate the effectiveness and usability of learning on campus when compared with traditional systems.
