| 摘 要： | 基于投影的增强现实系统是增强现实技术中的一个新的研究领域。针对基于投影增强现实技术的魔幻展台系统中的光照问题,我们提出了一套解决魔幻展台中真实场景与虚拟场景光照影响一致性的方法,给出了相关算法的关键代码,采用投影仪补充投射阴影的方法来实现虚拟物体的阴影制作,解决了真实场景与虚拟场景之间相互遮挡的问题,增强了魔幻展台中虚拟物体的真实感及与真实场景的一致性,取得了良好的效果。

| Abstract: | Projection-based AR system is a new field of study in the augmented reality technology and the magic showcase is a typical projection-based AR system.How to resolve the consistent illumination problems of the magic showcase and how to add the virtual shadow into the system for the virtual scene with a projector were proposed.The design concepts of the occlusion system between the real and the virtual scenes was introduced,and the method of realization including the main program was given.With these methods,the reality of the virtual objects and the consistency between the real were improved and the virtual scenes and the good effects were obtained in the experiments. |
