Paperback. Condizione: New. Print on Demand. This book explores the feasibilities and limitations of constructing objects from point cloud data, using I-beams as test subjects. The author details the process of using a high-resolution LADAR to scan and capture as-built data from an I-beam, and creates point cloud data to identify and locate the general pose, position, and orientation of the beam. Using two different approaches for identifying potential target objects, the author determines the I-beam's pose by examining the principal axes and using bounding boxes to compare the identified beam to an ideal I-beam model. The study demonstrates the possible uses of high-resolution LADAR and examines the difficulties presented by phantom pixels and mixed pixels in collected data. Through the use of reference spheres, the author registers the scans and SMS axes to one another and also compares the computed pose of the I-beam to measured poses. This book will be of special interest to those working in the field of construction object recognition and tracking, as well as those interested in developing automated crane control systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
