Rapid construction of indoor and outdoor three-dimensional scenes and augmented reality navigation design and application

Abstract

With the development trend of the information society, various scenarios are being digitized and informatized. At the same time, people's requirements for the visibility and convenience of travel navigation are constantly increasing. Combining AR (Augmented Reality) technology with navigation has become a hot topic. However, currently, the production of most 3D (three-dimensional) scenes is complex and time-consuming, and lacks indoor scenes. Mainstream AR navigation is costly and cannot be widely used. This paper uses quickly established lightweight 3D scene models, which, after secondary development, form a B/S architecture for indoor and outdoor 3D scene applications. Simultaneously, it combines Three.js 3D rendering library technology with device sensors to form a mobile AR navigation application. This system and application provide scene browsing, building query positioning, path planning, and AR path navigation functions. It has the advantages of low development cost, short cycle, and low hardware requirements for devices.
