Abstract


For the wrong occlusion relationship between the virtual and real objects is generated due to the spatial relationship in augmented reality, which makes it difficult for the user to distinguish the real relationship between the virtual and real objects, the influence of immersion and interaction. The background contour of the occlusion object is extracted by the improved background modeling method and the improved shadow removal method. The occlusion relationship between the virtual and real objects is determined by depth information recovery and pixel traversal. The occlusion recovery is completed by using OpenGL and OpenCV as graphics drawing and handling tools. Experimental verification shows that the virtual and real occlusion handling method can effectively recovery the correct virtual and real occlusion relationship.
