| Abstract | We propose a new stereo method for 2D navigation without depth search and metric camera calibration. Although there is such a stereo method using the constraint that a vehicle moves on flat planes, the conventional method has the following drawbacks. First, it lacks of an effective contrivance to deal with camera vibrations and road inclination. Second, there is no measure to assess the danger of detected obstacles. To solve these problems, we develop a domain-specific stereo method which utilizes attributes of roads. We introduce a new camera model that is valid in road scenes in order to simplify the epipolar geometry giving a useful relationship between a pair of images. Furthermore, extraction of two parallel lines marking the driving lane enables us to correctly detect obstacles and even to estimate the degree of the danger. The proposed method is implemented on a Pentium II 450 MHz PC and the current operating frequency is 15 Hz for 320/spl times/240 images without MMX instructions. Through experiments we demonstrate that our method is applicable to a variety of road scenes. |

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.
