Research On 3D Stereoscopic VR Image Based On Long Lens Theory

From the perspective of the global Internet,the emergence of AR,VR and other technologies and creative media,the proposal of the concept of"metaverse" centered on virtual reality technology,and the multiple rounds of demand driven by "contactless services" under the influence of the epidemic The virtual reality industry will achieve effective integration and rapid development in the short term.Virtual reality technology is an emerging fusion medium developed based on modern computer technology.In a broad sense,virtual reality refers to a three-dimensional space simulated on a computer,and users can experience an immersive experience in the virtual space through a head-mounted display device.With the continuous advancement and integration of virtual technology,the virtual reality industry is gradually refined,including virtual reality games,virtual reality images,and virtual reality entertainment projects.With the development of the Metaverse and the gradual marketization of head-mounted display devices,virtual reality has overcome many difficulties and gradually entered the audience’s attention.In the face of the gradually expanding consumer market and user population,the production of virtual reality content is becoming more and more important,and the audience is more interested in virtual reality.The requirements for authenticity and experience are also getting higher and higher.Other scholars’ research on virtual reality images mainly focuses on the research of virtual reality narrative,interaction and image language,but there is little research on how virtual reality images can achieve a better realistic experience.Most of them are based on academic research under theoretical background.The research on the theory of practice feedback is relatively scarce.The generation of realism is a subjective perception experience based on the real objective world and relying on the senses of sight,hearing,touch,smell and so on.The diversity of the sense of reality endows the multi-dimensional exploration of the reality of the image.How the virtuality of virtual reality itself cannot be eliminated and the sense of reality of the image can coexist is an important argument discussed in this paper.This paper focuses on the spatial field of vision of images.Based on Bazin’s long-lens theory,through the analysis and practice of traditional images and virtual reality images,it discusses how to reduce the virtuality of virtual reality from the visual level,enhance the audience’s real visual experience,and try to combine traditional and virtual reality.The means of creating a sense of reality by images have migrated to the field of virtual reality.In the context of long shots,it returns to practice from the aspects of distance and spatial composition,and tries to discuss how it affects the generation of virtual reality reality,so that the audience can have a real sense of "illusion".The main discussion path of this paper.
