基于视频图像的增强现实光照技术

光照一致性是增强现实技术中一项重要的研究内容。利用摄像机捕获的放置在真实场景中的标定物和镜面小球的视频图像,设计了一个增强现实光照系统模型。模型的实现过程表明,该方法实现相对简单,不需要对场景及模型进行预处理,能够达到虚实对象在动态增强现实场景中光照的实时一致性。

Real-time Consistent Illumination Based Video Images in Augmented Reality System

One of the important research targets in the Augmented Reality system is the consistent illumination of virtual objects with respect to the real-world environment.In this paper,we present an interactive real-time augmented reality system with the video image of a marker and a mirror ball that are placed in a scene with realistic illumination of integrated virtual objects.The image is captured by a video camera.Dynamic illumination is estimated from video signal and used for realistic real-time integration of virtual objects into the video.Such a conclusion may be drawn from the setup of the system that it is relatively simple to apply this method to arbitrary settings with little or no preparation or setup.
