Presentation Effect

On the purpose of presenting the old appearance of the relics through digitalization, and overlapping the virtual scenes with the actual scenes at the relic site, in this paper, we introduced the positioning technology, posture sensing technology and system development technology, put forward constructing cultural relic tourism platform based on integration positioning and posture sensing technology, we conducted detailed research and analysis on the users’ experienced process of cultural tourism, designed a relic augmented reality system of integration positioning and posture sensing technology. This augmented reality system mainly utilizes positioning technology to guide the users to the correct location of the relic on the corresponding map, and then overlaps the virtual object with the real relic, achieveing a 360-degree view of the overlapping effect, and the presentation effect of near-small, far-big. The system mainly employs Unity to develop the system and realize the above system on mobile terminal. It is no longer limited to a fixed point experience environment, and is suitable for outdoor natural scenes, it makes a breakthrough on the traditional overlapping of virtual scenes and real scenes, realizes the precise overlap of virtual 3D scenes with actual images, and enables the users to feel the vicissitudes of history along the movement of the mobile device in outdoor natural scenes, so as to inherit the history and culture, enrich the information and add some fun to the displayed scene, it has the advantages of bringing people more immersive feelings compared with the traditional virtual display platform.

The method presented in this work reduces the frequency of virtual objects incorrectly occluding real-world objects in Augmented Reality (AR) applications. Current AR rendering methods cannot properly represent occlusion between real and virtual objects because the objects are not represented in a common coordinate system. These occlusion errors can lead users to have an incorrect perception of the environment around them when using an AR application, namely not knowing a real-world object is present due to a virtual object incorrectly occluding it and incorrect perception of depth or distance by the user due to incorrect occlusions. The authors of this paper present a method that brings both real-world and virtual objects into a common coordinate system so that distant virtual objects do not obscure nearby real-world objects in an AR application. This method captures and processes RGB-D data in real-time, allowing the method to be used in a variety of environments and scenarios. A case study shows the effectiveness and usability of the proposed method to correctly occlude real-world and virtual objects and provide a more realistic representation of the combined real and virtual environments in an AR application. The results of the case study show that the proposed method can detect at least 20 real-world objects with potential to be incorrectly occluded while processing and fixing occlusion errors at least 5 times per second.
