| Abstract | Real-time 3D mapping has many applications and has recently received a large interest due to availability of consumer depth cameras at low prices. In this paper, we present a 3D registration and mapping method that heuristically switches between photometric and geometric features, therefore allowing it to accurately register scenes that may lack either visual or geometric information. We propose a novel informative sampling based geometric 3D feature extraction technique in which the points carrying the most useful geometric information are used for registration. This increases the computational speed significantly while preserving the accuracy of the registration when compared to using the dense point cloud for registration. After extracting the features from sequential frames, they are assigned with feature descriptors and matched with their correspondences from the previous frame. The matches are then refined and a rigid transformation between the frames is calculated using a highly robust estimator. A global pose for the camera and associated 3D position of the points are computed by concatenating the estimated relative transformations and a 3D map is constructed. We evaluate our method on publicly available RGB-D benchmark datasets [1] and compare it to the state of the art algorithms. |

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.
