Download or read book Map Construction Algorithms written by Mahmuda Ahmed and published by Springer. This book was released on 2015-12-17 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides an overview of the state-of-the-art of map construction algorithms, which use tracking data in the form of trajectories to generate vector maps. The most common trajectory type is GPS-based trajectories. It introduces three emerging algorithmic categories, outlines their general algorithmic ideas, and discusses three representative algorithms in greater detail. To quantify map construction algorithms, the authors include specific datasets and evaluation measures. The datasets, source code of map construction algorithms and evaluation measures are publicly available on http://www.mapconstruction.org. The web site serves as a repository for map construction data and algorithms and researchers can contribute by uploading their own code and benchmark data. Map Construction Algorithms is an excellent resource for professionals working in computational geometry, spatial databases, and GIS. Advanced-level students studying computer science, geography and mathematics will also find this book a useful tool.

Available in PDF, EPUB and Kindle. Book excerpt: Analyzing and mining various kinds of geo-referenced data is important in many application areas. We use two types of data: geo-referenced trajectories, such as vehicular tracking data, as well as geo-referenced graph data, such as street maps. This dissertation consists of two main parts. In the first part, we consider the problem of constructing street maps from geo-referenced trajectories: Given a set of trajectories in the plane, compute a street-map that represents all trajectories in the set. In this part, we have two main contributions. First, we present a scalable incremental algorithm that is based on partial matching of the trajectories to the graph. For the partial matching we introduce a new variant of partial Fréchet distance. We use minimum-link paths to reduce the complexity of the generated map. We provide quality guarantees and experimental results based on both real and synthetic data. We further present two multi-thresholding techniques for density-based map construction algorithms. Multi-thresholding is necessary because some streets are travelled more heavily than other streets (highways vs. neighborhood streets), which results in different sampling densities, and thus, one threshold fails to capture all the streets. We present a new thresholding technique that uses persistent homology combined with statistical analysis to determine a small set of thresholds that captures all or most of the significant topological features. We also formalize the selection of thresholds in a density-based map construction algorithm for different variants of uniform sampling. In part two of the dissertation, we consider the map comparison problem: Given two street-maps embedded in space, quantify their differences. Given maps of the same city collected from different sources, researchers often need to know how they differ. Map comparison is very important in the field of transportation network analysis as well as to assess the quality of map construction algorithms. We present a new path-based distance measure to compare two planar geometric graphs that are embedded in the same plane. Our distance measure takes structural as well as spatial properties into account. We show that it can be approximated in polynomial time and it preserves structural and spatial properties of the graphs. We provide experimental results comparing vendor quality street maps (TeleAtlas) with open source maps (OpenStreetMap), as well as maps generated by map construction algorithms with ground-truth maps (OpenStreetMap).

Download or read book Elements of Robotics written by Mordechai Ben-Ari and published by Springer. This book was released on 2017-10-25 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book bridges the gap between playing with robots in school and studying robotics at the upper undergraduate and graduate levels to prepare for careers in industry and research. Robotic algorithms are presented formally, but using only mathematics known by high-school and first-year college students, such as calculus, matrices and probability. Concepts and algorithms are explained through detailed diagrams and calculations. Elements of Robotics presents an overview of different types of robots and the components used to build robots, but focuses on robotic algorithms: simple algorithms like odometry and feedback control, as well as algorithms for advanced topics like localization, mapping, image processing, machine learning and swarm robotics. These algorithms are demonstrated in simplified contexts that enable detailed computations to be performed and feasible activities to be posed. Students who study these simplified demonstrations will be well prepared for advanced study of robotics. The algorithms are presented at a relatively abstract level, not tied to any specific robot. Instead a generic robot is defined that uses elements common to most educational robots: differential drive with two motors, proximity sensors and some method of displaying output to the user. The theory is supplemented with over 100 activities, most of which can be successfully implemented using inexpensive educational robots. Activities that require more computation can be programmed on a computer. Archives are available with suggested implementations for the Thymio robot and standalone programs in Python.

Download or read book Smartphone Based Indoor Map Construction written by Ruipeng Gao and published by Springer. This book was released on 2018-03-27 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on ubiquitous indoor localization services, specifically addressing the issue of floor plans. It combines computer vision algorithms and mobile techniques to reconstruct complete and accurate floor plans to provide better location-based services for both humans and vehicles via commodity smartphones in indoor environments (e.g., a multi-layer shopping mall with underground parking structures). After a comprehensive review of scene reconstruction methods, it offers accurate geometric information for each landmark from images and acoustics, and derives the spatial relationships of the landmarks and rough sketches of accessible areas with inertial and WiFi data to reduce computing overheads. It then presents the authors’ recent findings in detail, including the optimization and probabilistic formulations for more solid foundations and better robustness to combat errors, several new approaches to promote the current sporadic availability of indoor location-based services, and a holistic solution for floor plan reconstruction, indoor localization, tracking, and navigation. The novel approaches presented are designed for different types of indoor environments (e.g., shopping malls, office buildings and labs) and different users. A valuable resource for researchers and those in start-ups working in the field, it also provides supplementary material for students with mobile computing and networking backgrounds.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed Computing by Mobile Entities is concerned with the study of the computational and complexity issues arising in systems of decentralized computational entities operating in a spatial universe Encompassing and modeling a large variety of application environments and systems, from robotic swarms to networks of mobile sensors, from software mobile agents in communication networks to crawlers and viruses on the web, the theoretical research in this area intersects distributed computing with the fields of computational geometry (especially for continuous spaces), control theory, graph theory and combinatorics (especially for discrete spaces). The research focus is on determining what tasks can be performed by the entities, under what conditions, and at what cost. In particular, the central question is to determine what minimal hypotheses allow a given problem to be solved. This book is based on the lectures and tutorial presented at the research meeting on “Moving and Computing" (mac) held at La Maddalena Island in June 2017. Greatly expanded, revised and updated, each of the lectures forms an individual Chapter. Together, they provide a map of the current knowledge about the boundaries of distributed computing by mobile entities.
