本文提出了一个增强现实系统，具有正确的表示明暗和阴影。为了实现无缝增强现实系统，我们需要解决某些问题。几何配准和光度配准问题尤为重要。这些问题需要光源的位置和用户的观点。所提出的系统解决了这些问题，使用3D标记，它结合了2D正方形标记和镜球。2D标记和球分别用于估计真实的世界和虚拟世界之间的关系以及光源在真实的世界中的位置。
This paper proposes an augmented reality system with correct representation of shading and shadow. To realize a seamless augmented reality system, we need to resolve certain problems. The geometric and photometric registration problems are particularly important. These problems require the position of light sources and user's viewpoint. The proposed system resolves these problems using a 3D marker which combines a 2D square marker and a mirror ball. The 2D marker and the ball are used to estimate the relationship between the real and virtual worlds and the positions of light sources in the real world, respectively.
