| Abstract | Indoor parking localization systems face two major challenges: the absence of GPS coverage and the dynamic character of the parking environment. The absence of GPS coverage can be compensated by data fusion of several sensors in order to localize an object in a map of the environment. However, this map may constantly change due to the dynamic nature of a parking garage. This paper describes an improvement to indoor localizations by a new map representation approach. The algorithm is developed for the application of an indoor parking system. The car park's map is based on the known permanent elements of the environment in combination with the knowledge of possibly changing elements. The permanent elements (e.g. walls) are considered static objects, while the known changing elements (e.g. parked cars) are modeled as semi-static objects. Such a representation avoids constantly updating the map with newly detected objects. Our algorithm fulfills the real-time requirement of the localization task for a computer-controlled car through the use of a particle filter. The filter uses laser scanner measurements and odometry data to localize the car in a precalculated probability grid map, containing static and semi-static elements. The evaluation of the algorithm in a real car park scenario demonstrates the robustness and real-time capability of the proposed system with a RMS error in the absolute position of 0.33m and in the heading angle of 1.03° at a computation time of 10ms per cycle. |

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.
