| Abstract | This paper presents a novel method for indoor pedestrian tracking using inertial sensing and sonar sensors. The zero velocity updating technique, which is used to enhance the performances of inertial sensing, cannot observe heading, resulting in a horizontal position drift. Sonar sensors are used as complementary technique to correct heading. The main idea is to extract a partial map of surrounding walls. Sonar returns are processed via the Hough transformation to extract wall segments (line features). The first detected segments will initiate a wall landmark. The pedestrian relative distance to next detected segments that are associated to a stored wall landmark, is considered to be his relative distance to that wall. An extended Kalman filter based solution to Bearing-Range simultaneous localization and mapping is used. The state vector is a concatenation of pedestrian position and positions of first points of each stored wall landmark, to which the virtual Bearing-range measurements are pointing. Both inertial and coupled sonar inertial tracks are visually compared to the true trajectory. |

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.
