8/28/2008 - Capturing 3D Surfaces Simply With a Flash Camera MojoKid writes with this excerpt from Hot plumbing (linking to a video demonstration): "Creating 3D maps and worlds can be extremely labor exhaustive and time consuming. Also, the final result might not be all that exact or realistic. A new means grown-up by scientists at The health center of Manchester's School of minicomputer Science and Dolby Canada, however, might make capturing depth and textures for 3D surfaces as simple as shooting two big screen* with a digital camera — one with flash and one without. First an image of a surface is captured without flash. The problem is that the various roget's ii: the new thesaurusmain entry:new part of speech:adjective definition:not the same as what was previously known or done. fresh colors of a surface also reflect light differently, making it uphill to measure if the brightness dissimilitude is a service of depth or color. By taking a second photo with flash, however, the veridical colors of all visible portions of the surface can be captured. The two captured images fundamentally become a reflectance map (albedo) and a depth map (height field)." Read more of this story at Slashdot. More: - The rest... Mark Post A Comment!
