Abstract | This paper presents a method of grid-pattern design for a 3D vision sensor, which is based on the principles of color-encoded structured light, to improve the reconstruction efficiency. For a live scene, since the 3D measurement is desired to only capture a single image, this paper uses a color projector which can be controlled by a computer to generate arbitrary desired color patterns. A problem for color encoded projection, however, is the unique indexing of the light codes in the image. It is essential that each light grid be uniquely identified by incorporating the local neighborhoods in the pattern so that 3D reconstruction can be performed with only local analysis of a single image. This paper describes such a method in design of the special grid patterns to modulate the scene for fast 3D reconstruction. Experimental examples are provided to demonstrate the proposed methods using a given number of colors |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
