| Abstract | Industries are being swept up by the tide of market innovations originated from pervasive application of Robotics and Automation (RA). Given the critical role of RA in industry, it has become relevant for RA to have human-like decision making capabilities. Such enablers intrinsically require the use of flexible and robust 3D perception and control systems. In the process of automating complex automotive sub-assemblies, 3D vision-based recognition as well as grasping of complex objects is required not only for detection and categorization but also for pose estimation and robotic pick-and-place operations. In this paper, we propose a novel 3D visual perception system for sub-assembly automation based on a structured light 3D vision system. We use a novel geometric surface primitive patch segmentation approach based on Hough transforms to obtain accurate surface normal estimations from 3D point clouds for the identification of patch primitives. The most relevant primitives for our application include planar, cylindrical, conic and spherical surface patches. We extract primitive surface patches from automotive CAD models in DXF format. The models are then decomposed to simple entities such as planar polygons, vertexes and lines. Our resulting models based on the 3D point clouds are composed only by simple planes and cylinders. Our system takes advantage of the available CAD data for both object recognition and for pose estimation. Our experimental results demonstrate that we can achieve, in only a few seconds, a highly accurate pose and object class estimation. |

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.
