Download or read book A Three dimensional Laser Range Scanner Based on the Self mixing Effect in a Laser Diode written by Éric Gagnon and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades, the field of artificial vision has witnessed an overwhelming growth through academic research and increasing industry demands. One of the more exciting and promising developments in the field has taken form in the 3D vision paradigm. With the advent of 3D vision, the possibility to directly map in three dimensions the shape of an object has opened a wealth of new possibilities. The purpose of this work is to present the theory and design of a low-cost, portable and accurate 3D laser range scanning system. The system allows direct acquisition of 3D images from a scene. The proposed 3D imaging method uses a laser beam for measuring the distance to a target in a fixed point and computing its (X, Y, Z) coordinate in space. Through deflection of this beam using small motorized mirrors, a distant surface may be scanned into a full 3D range image. Unlike conventional ranging systems, the present design uses a single semiconductor laser diode serving as both a laser source and detector. Laser ranging is achieved through frequency modulation of the laser with time-of-flight coherent detection, based on the self-mixing effect in a laser diode. This allows for unambiguous range measurement capabilities over several meters. The benefits of this sensing approach over existing laser-based systems are numerous, and include: (1) Very low cost solution to the ranging problem. (2) No need for external optical sensing elements. (3) Coaxial source and detector configuration eliminates shadowing problems. (4) Coherent detection yields constant ranging error over useful workspace. (5) Velocity and range information available from a single measurement. (6) Interferometric scale measurements possible in fixed-frequency regime.

Available in PDF, EPUB and Kindle. Book excerpt: Three-Dimensional Imaging Techniques provides an overview of the development and practical applications of three-dimensional imaging techniques. This text deals with holographic and nonholographic techniques, with a focus on efficiency, speckle noise, resolution, white-light reconstruction, white-light recording, and color holography. This book is comprised of nine chapters, wherein Chapter 1 provides a brief history of information media in human society. Chapter 2 presents the history of depth perception and the principle of the Wheatstone stereoscope, and Chapter 3 examines the construction of human eyes as the most important source of depth perception. Chapter 4 focuses on the optimum design of lens-sheet pictures, whereas Chapters 5 and 6 examine the technical drawbacks that limit the versatility in three-dimensional imaging technology. The features of holographic techniques, such as holographic stereoscreens and computer-generated holograms, are discussed in Chapters 7 and 8. Finally, Chapter 9 discusses the possible classifications based on applications, including microscopy, television, X-ray imaging, movies, and acoustical imaging. This book is intended for electronic engineers, researchers, and readers who are interested in the field of three-dimensional imaging.

Available in PDF, EPUB and Kindle. Book excerpt: In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Download or read book 3D Imaging Analysis and Applications written by Yonghuai Liu and published by Springer Nature. This book was released on 2020-09-11 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is designed for postgraduate studies in the field of 3D Computer Vision. It also provides a useful reference for industrial practitioners; for example, in the areas of 3D data capture, computer-aided geometric modelling and industrial quality assurance. This second edition is a significant upgrade of existing topics with novel findings. Additionally, it has new material covering consumer-grade RGB-D cameras, 3D morphable models, deep learning on 3D datasets, as well as new applications in the 3D digitization of cultural heritage and the 3D phenotyping of crops. Overall, the book covers three main areas: ● 3D imaging, including passive 3D imaging, active triangulation 3D imaging, active time-of-flight 3D imaging, consumer RGB-D cameras, and 3D data representation and visualisation; ● 3D shape analysis, including local descriptors, registration, matching, 3D morphable models, and deep learning on 3D datasets; and ● 3D applications, including 3D face recognition, cultural heritage and 3D phenotyping of plants. 3D computer vision is a rapidly advancing area in computer science. There are many real-world applications that demand high-performance 3D imaging and analysis and, as a result, many new techniques and commercial products have been developed. However, many challenges remain on how to analyse the captured data in a way that is sufficiently fast, robust and accurate for the application. Such challenges include metrology, semantic segmentation, classification and recognition. Thus, 3D imaging, analysis and their applications remain a highly-active research field that will continue to attract intensive attention from the research community with the ultimate goal of fully automating the 3D data capture, analysis and inference pipeline.
Download or read book Multispectral Hyperspectral and Three Dimensional Imaging Research at the U S Army Research Laboratory written by and published by . This book was released on 2003 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report on the development and application of multispectral infrared imaging technology to problems of interest to the U.S. military. For tactical applications, we show the application of dual-band infrared focal plane arrays to reconnaissance, surveillance, and target acquisition. We describe the development of a new dual-band LWIR/LWIR focal plane array for detection of the disturbed soil features associated with buried land mines. We will describe the application of dual-band FPAs in the strategic defense arena by presenting dual-band MWIR/LWIR imagery of commercial launch vehicles that shows the utility of such an FPA for a sensor in a boost phase interceptor. In addition, we describe the development of acousto-optic tunable filters (AOTF) for hyperspectral imaging in the MWIR and LWIR bands. These devices hold the promise of producing hyperspectral infrared imagers that are considerably smaller and lighter than current systems. The AOTF allows completely electronic spectral scanning for fast access to a discrete set of narrow spectral bands. We will discuss ARL, s efforts in developing a novel scanerless laser radar (LADAR) system based on the frequency modulated continuous wave (FMCW) technique. This 'flash" LADAR system uses a focal plane array to image the return signals from chirped pulses from a solid state laser to determine both 2D image and range information about a target. This data can then be used to construct a 3-dimensional picture of the target. Keywords: Infrared, Multispectral, AOTF, Hyperspectral, LADAR.
