Available in PDF, EPUB and Kindle. Book excerpt: Lane width evaluation is one of the crucial aspects in road safety inspection. Moreover, lane width is one of the most important attributes of a road digital map for many applications, such as driver assistance systems and risk assessment. Using mobile mapping systems (MMSs) equipped with laser scanners is a safe and cost-effective method for rapidly collecting detailed information about various characteristics along any transportation corridor. This report presents an approach to derive lane width estimates using point clouds acquired from a calibrated mobile mapping system. To derive point clouds with high positional accuracy, estimation of the mounting parameters relating the different laser scanners to the onboard GNSS/INS unit is the foremost and necessary step. This report proposes a multi-unit LiDAR system calibration procedure where the mounting parameters can be estimated through minimizing the normal distance between conjugate planar/linear features in overlapping point clouds derived from different drive-runs. After generating the LiDAR point cloud using the estimated mounting parameters, the road surface can be extracted with the assistance of navigation data, which in turn is used to identify lane markings. Lane markings have a high retro-reflective property that will be exhibited as high-intensity points when scanned by a laser scanner. This property can be used to distinguish lane markings from the extracted road surface in the LiDAR point cloud. Then, non-lane marking points among the extracted high-intensity points are identified and removed. Next, the lane marking centerline is derived for lane width estimation.

Book Synopsis Shape, Contour and Grouping in Computer Vision by : David A. Forsyth
Download or read book Shape, Contour and Grouping in Computer Vision written by David A. Forsyth and published by Springer Science & Business Media. This book was released on 1999-11-03 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer vision has been successful in several important applications recently. Vision techniques can now be used to build very good models of buildings from pictures quickly and easily, to overlay operation planning data on a neuros- geon’s view of a patient, and to recognise some of the gestures a user makes to a computer. Object recognition remains a very di cult problem, however. The key questions to understand in recognition seem to be: (1) how objects should be represented and (2) how to manage the line of reasoning that stretches from image data to object identity. An important part of the process of recognition { perhaps, almost all of it { involves assembling bits of image information into helpful groups. There is a wide variety of possible criteria by which these groups could be established { a set of edge points that has a symmetry could be one useful group; others might be a collection of pixels shaded in a particular way, or a set of pixels with coherent colour or texture. Discussing this process of grouping requires a detailed understanding of the relationship between what is seen in the image and what is actually out there in the world.
Book Synopsis Laser Mobile Mapping Standards and Applications in Transportation by : Steven Johnson
Download or read book Laser Mobile Mapping Standards and Applications in Transportation written by Steven Johnson and published by . This book was released on 2016-11-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the work that was done to support the development of a chapter for the INDOT Survey Manual on Mobile Mapping. The work includes experiments that were done, data that was collected, analysis that was carried out, and conclusions that were drawn about accuracy of Mobile Terrestrial Laser Scanning (MTLS) systems. The resulting Manual chapter, located in the appendix, defines standards and procedures for preparing, collecting, editing, delivering, exploiting, and archiving electronic mapping data that is created for Indiana Department of Transportation (INDOT). The purpose of the standards and procedures within this manual is to obtain statewide uniformity within the INDOT combined Aerial/Ground Survey process, to establish and maintain MTLS Standards for INDOT and contracted consultants, and allow for all of the project data to be effectively managed from conception to completion. These standards apply to all projects delivered to INDOT by contracted consulting firms, or exchanged internally within INDOT or between state agencies. The standards and procedures are the result of mobile terrestrial laser scanning surveys of two test sites - one urban and one freeway - created for this project. After establishing reference control points on the sites, each site was surveyed by four mobile terrestrial laser scanning vendors. The results from the vendor data over the test sites, in addition to information in published literature, are the basis for the specifications manual. The proposed chapter for the Survey Manual is in Appendix E of this report.

Download or read book Urban Informatics written by Wenzhong Shi and published by Springer Nature. This book was released on 2021-04-06 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.
