| Abstract | We propose a novel image segmentation algorithm to tackle the challenge of limited recognition and segmentation performance in identifying welding seam images during robotic intelligent operations. Initially, to enhance the capability of deep neural networks in extracting geometric attributes from depth images, we developed a novel deep geometric convolution operator (DGConv). DGConv is utilized to construct a deep local geometric feature extraction module, facilitating a more comprehensive exploration of the intrinsic geometric information within depth images. Secondly, we integrate the newly proposed deep geometric feature module with the Fully Convolutional Network (FCN8) to establish a high-performance deep neural network algorithm tailored for depth image segmentation. Concurrently, we enhance the FCN8 detection head by separating the segmentation and classification processes. This enhancement significantly boosts the network’s overall detection capability. Thirdly, for a comprehensive assessment of our proposed algorithm and its applicability in real-world industrial settings, we curated a line-scan image dataset featuring weld seams. This dataset, named the Standardized Linear Depth Profile (SLDP) dataset, was collected from actual industrial sites where autonomous robots are in operation. Ultimately, we conducted experiments utilizing the SLDP dataset, achieving an average accuracy of 92.7%. Our proposed approach exhibited a remarkable performance improvement over the prior method on the identical dataset. Moreover, we have successfully deployed the proposed algorithm in genuine industrial environments, fulfilling the prerequisites of unmanned robot operations. |

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.
