| Abstract | In this paper, we present an approach targeting the automated road map generation for autonomously driving vehicles using low-cost GPS sensor data in a multi-drive setup. Multiple drives with deployed commodity smartphone and stereo camera system are recorded as input data. To overcome the high position uncertainties of the GPS sensor, the GPS trajectory is fused with ego-motion estimates of the vehicle computed by visual odometry. Landmarks are extracted from the recorded imagery data and fused over all recorded drives. The resulting road map consists of a simple, parametric representation of globally referenced lane markings with low storage impact. The challenging aspect in this work is the feature association between multiple drives. Different characteristics of dashed center lines are exploited for this purpose to handle the low precision of the sensor data. The resulting association information is the building block for graph-based SLAM to optimize vehicle poses and landmarks simultaneously. The approach is finally evaluated on real world data comparing the low-precision sensor data with high-precision sensor data as ground-truth. |

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.
