| Abstract | Today optical motion capture system is becoming an essential tool for motion analysis, synthesis, and character animation. This paper focuses on improving the ability of current passive optical motion capture systems, which provides the highest precision and flexibility with the lowest interference among current motion capture technologies but has two major drawbacks. Firstly, it usually requires expensive post-processing computation including reconstruction and labeling. The second problem is that it is difficult to achieve both high precision and high frame rate at the same time due to the limitation of data transmission rate, that is, high-resolution cameras have low frame rate and vice versa. In this paper, we try to solve these problems by combining cameras of different types that complement the limitations of each others. The marker positions measured by the high-resolution cameras correct the low-precision data from high-speed cameras, which in turn helps real-time tracking of markers by inserting new data at higher frame rate. The proposed method is implemented on a PC cluster and experimental results show that we can obtain high-precision data even for high-speed motions. We also demonstrate the real-time joint angle computation using the real-time tracking capability. |

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.
