Book excerpt: Maintenance and modernization efforts of the U.S. Navy s fleet are essential to the U.S. s ability to project power and deter adversaries from around the world. This maintenance and modernization requires substantial allocation of funds from the already stretched thin budget. In order to facilitate the most cost-effective way of allocating funds the Navy has invested substantial fiscal and human resources to standardize the processes used to accomplish maintenance, modernization and repair for its fleet of ships. In order to realize the full benefit to the available technology, reliable and quantitative measures which capture and measure the full range of benefits provided by technology resources are essential. The Knowledge Value Added (KVA) methodology will be used in this thesis to identify and quantify the benefits that can be realized within the cost estimation portion of the ship maintenance and modernization (SHIPMAIN) program. A proof of concept case was developed to analyze the current cost estimation process with SHIPMAIN. After the completion of the baseline as-is process, the KVA methodology is applied to a notional scenario which uses 3D laser scanning and Product Lifecycle Management to reengineer the current cost estimation process. The notional scenario demonstrates positive returns from the reengineered cost estimation process and the KVA methodology establishes evidence which suggests that operating costs will be reduced by over $176 million and cost estimation efficiency will increase.

This book was released on 2007 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance and modernization of the U.S. Navy fleet is big business. To get the most value for each dollar spent, the Navy has invested substantial fiscal and human resources to standardize the processes used to accomplish maintenance, modernization and repair for its fleet of ships. As technology continues to advance at an exponential rate, reliable and quantitative measures which capture and measure the full gamut of benefits provided by technology resources are essential. An analytic form of analysis known as the Knowledge Value Added (KVA) methodology will be used in this thesis to capture and quantify the benefits of the ship maintenance and modernization (SHIPMAIN) program and the potential benefits offered by a reengineered process. A proof of concept case was developed to analyze current maintenance and modernization efforts for combatant ships of the Navy's surface forces. Using the current status as a baseline analysis, the KVA methodology is applied to a notional scenario which uses 3D laser scanning and Product Lifecycle Management to reengineer the current process. The notional scenario demonstrates positive returns from the reengineered process and the KVA methodology establishes evidence which suggests that operating costs will be reduced by nearly 7 8 million annually.

This book was released on 2011 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continual modernization and maintenance efforts are essential to ensure the U.S. Navy's ability to commit naval assets to deter adversaries abroad and contribute meaningfully to national security. Despite budgetary pressures to reduce defense expenditures, the need for deployable platforms remains constant. To address this tension between a reduction in resources matched with a constant demand signal, the U.S. Navy has invested considerable fiscal and human capital to develop effective and efficient processes by which to accomplish maintenance, modernization and repair for fleet assets. Using a Knowledge Value Added (KVA) methodology, this thesis looks to identify and quantify additional cost savings that can be achieved in the U.S. Navy's Ship Maintenance and Modernization Program (SHIPMAIN) through use of collaborative information technologies. Specifically, this study will look at the value of applying the Common Parts Catalog (CPC), a collaborative tool in use at many major shipbuilders, to direct use in SHIPMAIN. An analysis of a To-Be model of the SHIPMAIN process with CPC with the current As-Is model of SHIPMAIN suggests savings in excess of $2 0 million a year can be achieved over current processes.

Abstract:  Image-based rendering (IBR) is an emerging technology for rendering photo-realistic views of scenes from a collection of densely sampled images or videos. It provides a framework for developing revolutionary virtual reality and immersive viewing systems. There has been considerable progress recently in the capturing, storage and transmission of image-based representations. This thesis proposes two image-based rendering (IBR) systems for improving the viewing freedom and environmental modeling capability of conventional static IBR systems. The first system consists of a circular array with 13 still cameras (Canon 550D) for capturing ancient Chinese artifacts at high resolution. The second one is constructed by mounting a linear array of 8 video cameras (Sony HDR-TGIE) on an electrically controllable wheel chair with its motion being controllable manually or remotely through wireless local area network (LAN) by means of additional hardware circuitry. Both systems support object-based rendering and 3D reconstruction capability and consist of two main components. 1) A novel view synthesis algorithm using a new segmentation and mutual information (MI)-based algorithm for dense depth map estimation, which relies on segmentation, local polynomial regression (LPR)-based depth map smoothing and MI-based matching algorithm to iteratively estimate the depth map. The method is very flexible and both semi-automatic and automatic segmentation methods can be employed. They rank fourth and sixth, respectively, in the Middlebury comparison of existing depth estimation methods. This allows high quality renderings of outdoor and indoor scenes with improved mobility/freedom to be obtained. This algorithm can also be extended to object tracking. Experimental results also show that the proposed MI-based algorithms are applicable to robust registration in noisy dynamic ultrasound images. 2) A new 3D reconstruction algorithm which utilizes sequential-structure-from-motion (S-SFM) technique and the dense depth maps estimated previously. It relies on a new iterative point cloud refinement algorithm based on Kalman filter (KF) for outlier removal and the segmentation-MI-based algorithm to further refine the correspondences and the projection matrices. The mobility of our system allows us to recover more conveniently 3D model of static objects from the improved point cloud using a new robust radial basis function (RBF)-based modeling algorithm to further suppress possible outliers and generate smooth 3D meshes of objects. Moreover, a new rendering technique named view dependent texture mapping is used to enhance the final rendering effect. Experimental results show that the proposed 3D reconstruction algorithm significantly reduces the adverse effect of the outliers and produces high quality renderings using view dependent texture mapping and the model reconstructed. Overall, this study provides a framework for designing IBR systems with improved viewing freedom and ability to cope with moving and static objects in indoor and outdoor environment.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retrieving 3D data using imaging devices is a relevant task for many applications in medical imaging, surveillance, industrial quality control, and others. As soon as we gain procedural control over parameters of the imaging device, we encounter the necessity of well-defined reconstruction goals and we need methods to achieve them. Hence, we enter next-best-view planning. In this work, we present a formalization of the abstract view planning problem and deal with different planning aspects, whereat we focus on using an intensity camera without active illumination. As one aspect of view planning, employing a controlled environment also provides the planning and reconstruction methods with additional information. We incorporate the additional knowledge of camera parameters into the Kanade-Lucas-Tomasi method used for feature tracking. The resulting Guided KLT tracking method benefits from a constrained optimization space and yields improved accuracy while regarding the uncertainty of the additional input. Serving other planning tasks dealing with known objects, we propose a method for coarse registration of 3D surface triangulations. By the means of exact surface moments of surface triangulations we establish invariant surface descriptors based on moment invariants. These descriptors allow to tackle tasks of surface registration, classification, retrieval, and clustering, which are also relevant to view planning. In the main part of this work, we present a modular, online approach to view planning for 3D reconstruction. Based on the outcome of the Guided KLT tracking, we design a planning module for accuracy optimization with respect to an extended E-criterion. Further planning modules endow non-discrete surface estimation and visibility analysis. The modular nature of the proposed planning system allows to address a wide range of specific instances of view planning. The theoretical findings in this work are underlined by experiments evaluating the relevant terms.
