    • The three dimensional surface shape of a specular reflective object can be determined by examining a captured image reflected from the object. Flat specular reflective surfaces, e.g. a mirror, provide an undistorted reflected image, while curved surfaces reflect a distorted image altered by the surface shape. By analyzing one or more captured images of the distorted reflection, one can estimate the shape of the surface that caused the distortion. A captured distorted image can be compared to a reference undistorted image for which one knows some geometric properties. A system to capture and process such images can be assembled from a few components including a computer to generate and process the images, a display to project the image onto the reflective object, a digital camera to capture the reflected image and a positioning device on which to orient the components with respect to each other.
    • 可以通过检查从物体反射的拍摄图像来确定镜面反射物体的三维表面形状。 平面镜面反射表面,例如 一个镜子,提供一个不失真的反射图像,而曲面反映由表面形状改变的扭曲图像。 通过分析失真反射的一个或多个拍摄图像,可以估计导致失真的表面的形状。 捕获的失真图像可以与参考未失真的图像进行比较,对于其参考未失真的图像,其中知道一些几何属性。 捕获和处理这样的图像的系统可以从包括计算机在内的几个部件组装起来以产生和处理图像,将图像投影到反射物体上的显示器,用于捕获反射图像的数字照相机和定位装置 以使组件相对于彼此定向。
