A Study Of Virtual Reality Occlusion In Augmented Reality

Augmented reality technology is developed on the basis of virtual reality technology,which combines virtual model technology,image processing technology,video processing technology and camera technology and other fields of technology.One of the key technologies of augmented reality technology is virtual and real fusion technology,virtual and real integration technology refers to the use of virtual and real occlusion technology and artificial interaction technology to make the virtual scene with more real effects and more interactive features.The virtual and real occlusion technology can make the scene more real fusion effect by judging the occlusion relationship between the virtual object and the real object in the scene.The accuracy of the occlusion relation between the virtual object and the object in the real scene determines whether the scene after the fusion of the virtual and real objects in the Augmented Reality is real enough.In this paper,the virtual and real occlusion technology is studied,and the actual and actual occlusion techniques are analyzed.On this basis,a real-time and better real-time occlusion method is proposed.This paper mainly studies three parts,which are the outline of the object,the occlusion relation,the occlusion and the elimination.In order to obtain the background contour of objects,we improved the background modeling and shadow removal,and improved and optimized the PBAS algorithm for the background modeling method,so as to obtain more accurate real object contours.Based on rgI,the brightness information is used to detect and remove shadows,and the contours of real objects are optimized.Judgment of virtual and real occlusion relation is realized by combining depth-distribution based on depth-gradient hypothesis and pixel-based traversal method.At the same time,the depth distribution method is improved and optimized to make the occlusion judgment of virtual object more rapid and more accurate.Finally,the frame caching technology is used to block the objects,and the object occlusion is eliminated.The experimental results show that the proposed algorithm is more accurate in occlusion.
