| Abstract | This paper describes pipelined hardware architecture for real-time laser point position detection system by using FPGA. This system processes 640×480 resolution images that were received by the CCD camera. We detected the position of the laser point through the following 5 steps. First, the screen area is detected by Homography transform by using chess board. Second, the system converts the inputted image to HSV color space. Third, HSV color space image is converted to binary image by using threshold value. Fourth, detect the laser point and also the position of the laser point on the binary image. Fifth, Homography transform algorithm is used to convert position of laser point input image to screen image. We can detect position of the laser point input image at real-time by using a dedicated parallel hardware. By using Homography transform algorithm, we can reduce error rate of detection of position. Moreover, we can implement a robust system in various environments. Furthermore, we can also reduce latency of system as this system can show the location of laser point at next frame. |

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.
