RESEARCH ON AUGMENTED REALITY DISPLAY TECHNOLOGY OF CULTURAL RELICS – TAKE THE BELL AND DRUM TOWER ON THE CENTRAL AXIS OF BEIJING, CHINA AS AN EXAMPLE

Abstract. The current global digital technology is in the era of accelerated iteration, with 5G, AR, VR and other technologies of scientific and technological research, new application scenarios of heritage buildings have also achieved innovative breakthroughs. This paper comprehensively reviews the development status of augmented reality display technology, and takes Beijing Drum Tower, an important conservation display technology innovation pilot of Beijing's central axis heritage application, as a theoretical and practical research blueprint. With full respect for the conservation requirements of the heritage buildings, the most appropriate and lightest augmented reality display means are used to fully express and explain the architectural heritage connotation and strengthen the public interactive experience. Through case analysis, a systematic technical process of augmented reality display design for heritage buildings is summarized and formed, and a practical guide for the technical adaptation of heritage buildings is established. Finally, facing the trend of innovative exploration of augmented reality technology and devices, the future development of AR technology in the field of cultural and museums was foreseen.
