| Abstract | For Robot visual location, a locating method based on Non-linear mapping Planar Orientation using improved Radial Bias Function (RBF) network is presented. To improve the adaptability on the camera's pose change, this method uses the pitch degree of camera as one of the input of RBF network, makes use of the non-linear approach of RBF network fits the non-linear mapping relationship from the image plane to the special plane, and positions the targets. In order to reduce the interaction between the RBF's feeling domains, improve the locating accuracy, a Gaussian core function which could inhibit the nuclear feeling domain is presented, and the improved RBF network take the Gaussian core function for the use of RBF, the locating accuracy is enhanced. In order to reduce the redundancy in RBF network's initial center selection, an improved method for initial center selection is proposed, this method form the samples in accordance with the norm, taking into account the infection of network's implicit nodes and preset a redundant threshold. Setting different pitch degrees, the results of locating experiments express this method is effective in the application of target locating on the special plane. The comparison of results of locating experiments shows that, under the same condition, the precision of this method is higher than the precision of the visual locating methods based on planar homography matrix estimation which is in common use. |

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.
