【摘要】 在增强现实系统中,虚拟物体与真实环境之间具有相匹配的亮度关系,会使虚实融合达到逼真的效果。为了获得虚实物体的亮度匹配,根据图像亮度处理的原理,对增强现实系统的虚实环境提出了整体和局部两种亮度评价算法,并对新型光学透视式头盔显示器的亮度匹配算法进行了改进,提高了系统效率。实验结果表明,对在不同情况下的真实环境和虚拟物体来说,这两种算法各有其优点,调节后的结果是理想的。更多还原

【Abstract】 In an augmented reality(AR) system,whether the intensity of virtual object can match with real scene is a crucial problem,and it can influence whether the compositing of real and virtual worlds is vivid.In order to achieve intensity matching,two method of evaluating real-virtual intensity are proposed based on the theory of dealing with the imaging intensity.According to a new design of optical see-through HMD,the methods are improved,and the system efficiency is boosted.The experiment results indicate that each method has its own strongpoint aim at the different real-virtual situation,and the results of the adjusting are more perfect.更多还原
