增强现实中基于轮廓深度恢复的虚实遮挡方法研究

针对增强现实系统中的虚实场景遮挡问题,提出一种基于立体视觉与前景轮廓深度重建的虚实遮挡恢复新方法.首先设计了一种基于色彩与亮度相结合的前景物体轮廓提取方法,以避免阴影对轮廓提取所造成的负面影响,系统随后利用立体视觉原理与插值技术恢复出前景轮廓以及轮廓内部的深度信息,为恢复虚拟与真实场景之间的正确遮挡关系提供依据.实验结...

STUDY ON OCCLUSION BETWEEN VIRTUAL SCENE AND REAL OBJECT BASED ON CONTOUR DEPTH RECOVERY IN AUGMENTED REALITY

In view of the occlusion problem between virtual scene and real objects in augmented reality,this paper proposes a new occlusion recovery method based on stereo vision and foreground contour depth reconstruction.To avoid the negative influence of shadows on contour subtraction,we firstly design a contour subtraction approach for foreground objects based on the combination of colour and brightness.Then,system restores the contour of foreground and its inner depth information by utilizing stereo vision princi...
