我们介绍了SpaceRelighter,这是一个基于投影仪的混合现实系统,它记录真实场景中的照明,并在稍后通过将光图案投影到场景中来再现它。用户无需佩戴头盔显示器等特殊设备,即可看到虚拟照明的真实场景。由于虚拟照明和真实场景是在真实的3D环境中融合的,而不是在2-D显示上,因此用户有更好的真实感。我们首先解释了通过光度学和几何转换来估计光图案的原理。然后,我们描述了一种通过使用多个摄像机和多个投影仪来减少遮挡问题的扩展方法。我们构建了一个原型系统,包括两个摄像头和两个投影仪,以确认可以使用投影仪再现照明。
We introduce SpaceRelighter , a projector-based mixed reality system that records illumination in a real scene and reproduces it at a later time by projecting a light pattern onto the scene. Users can see a virtually illuminated real scene without having to wear special devices such as a head-mounted display. Because the virtual illumination and real scene are merged in a real 3-D environment and not on a 2-D display, users have a better sense of reality. We first explain the principle of estimating light patterns by photometric and geometric conversion. We then describe an extended method for reducing the problem of occlusion by using multiple cameras and multiple projectors. We constructed a prototype system including two cameras and two projectors to confirm that illumination can be reproduced using projectors.
