Title: | Fast normal map acquisition using an LCD screen emitting gradient patterns | Authors: | FRANCKEN, Yannick HERMANS, Chris CUYPERS, Tom BEKAERT, Philippe |
Issue Date: | 2008 | Publisher: | IEEE COMPUTER SOC | Source: | PROCEEDINGS OF THE FIFTH CANADIAN CONFERENCE ON COMPUTER AND ROBOT VISION. p. 189-195. | Abstract: | We propose an efficient technique for normal map acquisition, using a cheap and easy to build setup. Our setup consists solely of off-the-shelf components, such as an LCD screen, a digital camera and a linear polarizer filter The LCD screen is employed as a linearly polarized light source emitting gradient patterns, whereas the digital camera is used to capture the incident illumination reflected off the scanned object's surface. Also, by exploiting the fact that light emitted by an LCD screen has the property of being linearly polarized, we use the filter to surpress any specular highlights. Based on the observed Lambertian reflection of only four different light patterns, we are able to obtain a detailed normal map of the scanned surface. Overall, our techniques produces convincing results, even on weak specular materials. | Notes: | Hasselt Univ tUL IBBT, Expertise Ctr Digital Media, Diepenbeek, B-3590 Belgium. | Document URI: | http://hdl.handle.net/1942/8463 | ISBN: | 978-0-7695-3153-3 | ISI #: | 000258320300023 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2009 |
