Today the cost of solid-state two-dimensional imagers has dramatically dropped, introducing low cost systems on the market suitable for a variety of applications, including both industrial and consumer products. However, these systems can capture only a two-dimensional projection (2D), or intensity map, of the scene under observation, losing a variable of paramount importance, i.e., the arrival time of the impinging photons. Time-Of-Flight (TOF) Range-Imaging (TOF) is an emerging sensor technology able to deliver, at the same time, depth and intensity maps of the scene under observation. Featuring different sensor resolutions, RIM cameras serve a wide community with a lot of applications like monitoring, architecture, life sciences, robotics, etc. This book will bring together experts from the sensor and metrology side in order to collect the state-of-art researchers in these fields working with RIM cameras. All the aspects in the acquisition and processing chain will be addressed, from recent updates concerning the photo-detectors, to the analysis of the calibration techniques, giving also a perspective onto new applications domains.

Timing Jitter In Time Of Flight Range Imaging Cameras written by Gehan Anthonys and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2022 with categories.

This book explains how depth measurements from the Time-of-Flight (ToF) range imaging cameras are influenced by the electronic timing-jitter. The author presents jitter extraction and measurement techniques for any type of ToF range imaging cameras. The author mainly focuses on ToF cameras that are based on the amplitude modulated continuous wave (AMCW) lidar techniques that measure the phase difference between the emitted and reflected light signals. The book discusses timing-jitter in the emitted light signal, which is sensible since the light signal of the camera is relatively straightforward to access. The specific types of jitter that present on the light source signal are investigated throughout the book. The book is structured across three main sections: a brief literature review, jitter measurement, and jitter influence in AMCW ToF range imaging.

Time-of-flight (TOF) cameras provide a depth value at each pixel, from which the 3D structure of the scene can be estimated. This new type of active sensor makes it possible to go beyond traditional 2D image processing, directly to depth-based and 3D scene processing. Many computer vision and graphics applications can benefit from TOF data, including 3D reconstruction, activity and gesture recognition, motion capture and face detection. It is already possible to use multiple TOF cameras, in order to increase the scene coverage, and to combine the depth data with images from several colour cameras. Mixed TOF and colour systems can be used for computational photography, including full 3D scene modelling, as well as for illumination and depth-of-field manipulations. This work is a technical introduction to TOF sensors, from architectural and design issues, to selected image processing and computer vision methods.

An important task in computer vision is to recover 3D information of the world around us. A 3D time-of-flight (TOF) camera is one specific emerging technology developed for 3D measurement and is now extensively used in areas such as robotics, automotive and security. The purpose of this book is to develop an important understanding of the measurement processes of 3D TOF cameras and to exploit the potential of 3D image technology in computer vision applications. An important step prior to developing high performance TOF camera applications is the formulation of a detailed and accurate statistical model of the measurements. In this work, a robust framework of signal-to-noise ratio is developed that provides an in-depth information of range estimation in these cameras. The process of 3D TOF camera measurement is understood by examining the reflectance modelling of objects to develop a unified radiometric model for TOF camera. Applications related to smart automotive industry by developing a four dimensional obstacle detection algorithm is also presented. Throughout this work, real and simulated data is used for empirical analysis and verification of applications and algorithms.

Cameras for 3D depth imaging, using either time-of-flight (ToF) or structured light sensors, have received a lot of attention recently and have been improved considerably over the last few years. The present techniques make full-range 3D data available at video frame rates, and thus pave the way for a much broader application of 3D vision systems. A series of workshops have closely followed the developments within ToF imaging over the years. Today, depth imaging workshops can be found at every major computer vision conference. The papers presented in this volume stem from a seminar on Time-of-Flight Imaging held at Schloss Dagstuhl in October 2012. They cover all aspects of ToF depth imaging, from sensors and basic foundations, to algorithms for low level processing, to important applications that exploit depth imaging. In addition, this book contains the proceedings of a workshop on Imaging New Modalities, which was held at the German Conference on Pattern Recognition in Saarbrücken, Germany, in September 2013. A state-of-the-art report on the Kinect sensor and its applications is followed by two reports on local and global ToF motion compensation and a novel depth capture system using a plenoptic multi-lens multi-focus camera sensor.

Correlating Time-of-Flight (TOF) camera systems provide a novel approach to indirect range measurement. These systems pack the accuracy of common one-point TOF range measurements inside each pixel of a digital video camera. The user therefore receives a complete depth map of the acquired scene. Simultaneously, the system provides a grayscale image of the scene thus delivering also the common data received from every 2D grayscale camera. Today, at least two different technical realisations of the measurement principle are available as prototype camera systems, though the problems - especially the core principal's systematic errors are yet to be completely understood and described. This book is the first of its kind, providing the user with solutions to problems that are likely to arise in real life applications. The measurement principle including its underlying model is discussed and an error analysis of the model is provided. A practical kick-start guide allows the user to quickly acquire acceptable range data from their TOF camera system.

Imaging technology is an important research area and it is widely utilized in a growing number of disciplines ranging from gaming, robotics and automation to medicine. In the last decade 3D imaging became popular mainly driven by the introduction of novel 3D cameras and measuring devices. These cameras are usually limited to indoor scenes with relatively low distances. Benjamin Langmann introduces medium and long-range 2D/3D cameras to overcome these limitations. He reports measurement results for these devices and studies their characteristic behavior. In order to facilitate the application of these cameras, common algorithms are adapted to the 2D/3D data and new approaches for standard computer vision tasks are introduced.
