中文简介:
Mirrors are used to make wide field of view (FOV) refractive images. The nonlinearity of incident and reflected light depends on the mapping between the shape of the mirror and the studies that have been done using caustics. We analyze this mapping using two plane light field parameters, which provide valuable insight into the geometry of reflected light. Using this analysis, we study the problem of producing a single view virtual image of a catadioptric system, which is impossible to achieve in several common configurations. Instead of minimizing a single image distortion, we propose to capture all the light through the captured light field to produce a virtual perspective. We think that the rotating symmetrical mirror shows that the results of the traditional plane light field are significantly distorted. We propose an axial light field, which is captured by the camera along the rotation axis of the mirror. It can effectively sample and eliminate the aliasing artifacts. This enables us to calculate and generate virtual wide field of view in a more widely used category of mirrors, without prior or depth estimation of the scene. We analyze the relationship between the axial field parameters and the field of view / resolution resulting from the virtual angle. The actual results of the spherical reflector used show that 140 ° FOV virtual viewing angle is generated by using multiple 30 ° FOV images.
课程简介: 镜子被用来使宽视场（FOV）的折反射成像。入射和反射光的非线性依赖于镜子的形状和已使用焦散线研究之间的映射。我们分析这个映射使用两个平面光场参数，它提供了宝贵的洞察反射光线的几何结构。使用这种分析，我们研究产生的折反射系统的单一视角的虚拟图像的问题，这是不可能实现的几种常见配置。而不是最小化中出现的一个单一的图像失真，我们提出了捕捉所有的光线需要通过捕获的光场产生一个虚拟的视角。我们认为，旋转对称的镜子，表明传统的平面光场的结果显着走样。我们提出了轴向光场，通过摄像机沿反射镜的旋转轴运动捕获的，高效的采样和消除混叠假象。这使我们能够计算生成虚拟视角宽视场在使用更广泛的一类的镜子，不使用场景的先验或深度估计。我们分析了轴向光场参数和视场/解决由此产生的虚拟的角度之间的关系。使用的球面反射镜的实际结果表明使用多个30◦视场图像生成140◦FOV虚拟视角。
