| Abstract | In visual servo system, there are problems on time delay by image processing and difference between image processing period and control period. In order to overcome these problems, the estimated image feature applied to a fixed camera has been proposed. Since the compensation of delay utilizes image Jacobian matrices which represent geometric models of manipulator and camera, it is affected by their calibration error. Therefore, this paper proposes a new visual servo system for active camera using estimated image feature with a simple on-line calibration. In order to reduce estimation error of image feature, the proposed method is calibrating each element of image Jacobian matrices from error of the estimated image feature. It is simple algorithm and few calculation amount compared to calibrating each parameters correctly such as internal camera parameters and orientation of manipulator and camera. The effectiveness of the proposed strategy is confirmed by a moving object tracking by a manipulator and an active camera |

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.
