Abstract:
The three dimensional surface shape of one or more layers of a reflective object is determined by examining one or more captured images reflected from the reflective object. Curved surfaces reflect a distorted image altered by the surface shape. By analyzing one or more captured images of the distorted reflected images, the shape of the surface that caused the distortion is estimated. A captured distorted image is compared to a reference undistorted image having known geometric properties. A system to capture and process such images is assembled from components including an image capture assembly such as a digital camera to capture reflected images and a positioning assembly on which to orient the components with respect to each other. Multiple surface layers of the reflective object are separately estimated using polarizations, luminance levels, chroma values or combinations thereof contained in one or more captured images.
