| Abstract | This paper proposes a noise-resilient road surface and free space estimation method using dense stereo. The proposed road surface estimation method selects 3D points expected to compose a road surface using YZ-plane accumulation, and then finds the road surface by sequentially estimating a piece-wise linear function based on a RANSAC framework. This makes our method insensitive to 3D points on obstacles and stereo matching errors on textureless road regions. The proposed free space estimation method is based on the fact that disparities from roads and obstacles should be equal at the free space boundary. This method calculates disparity consistency between road and obstacle surfaces, and finds free space that gives the best disparity consistency and depth smoothness using dynamic programming. This approach achieves robustness against stereo matching errors on obstacle surfaces and objects located in the air since its estimation process is independent of disparity accumulation unlike previous occupancy grid-based method. The experimental results show that the proposed method is able to estimate road surfaces and free spaces in various severe situations. |

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.
