| Abstract | This paper presents a modular software architecture based on a stereo camera system that makes real-time 3D perception, interaction and navigation for small humanoid robots possible. The hardware-independent architecture can be used for several purposes, like 3D visualisation, object recognition, selflocalization, collision avoidance et cetera. First of all, the intrinsic calibration parameters of the stereo camera system are identified. Then the lens distortions of the input images are revised, and both images are rectified according to the extrinsic parameters to facilitate the subsequent correspondence analysis. The imaged scenery, as well as a region of interest, can be reconstructed either by the block-matching, the Schirai- or the Birchfield algorithm, followed by triangulation back into 3D space. Finally, the above-mentioned aims can be tackled based on the resulting 3D model computed by our modular software architecture. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
