Using this, it reformulates existing three-dimensional reconstructing methods, expands upon them and develops new ones.
Book Synopsis Dynamic Deformation, Damage and Fracture in Composite Materials and Structures by : Vadim Silberschmidt
Download or read book Dynamic Deformation, Damage and Fracture in Composite Materials and Structures written by Vadim Silberschmidt and published by Woodhead Publishing. This book was released on 2016-01-23 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite materials, with their higher exposure to dynamic loads, have increasingly been used in aerospace, naval, automotive, sports and other sectors over the last few decades. Dynamic Deformation, Damage and Fracture in Composite Materials and Structures reviews various aspects of dynamic deformation, damage and fracture, mostly in composite laminates and sandwich structures, in a broad range of application fields including aerospace, automotive, defense and sports engineering. As the mechanical behavior and performance of composites varies under different dynamic loading regimes and velocities, the book is divided into sections that examine the different loading regimes and velocities. Part one examine low-velocity loading and part two looks at high-velocity loading. Part three then assesses shock and blast (i.e. contactless) events and the final part focuses on impact (contact) events. As sports applications of composites are linked to a specific subset of dynamic loading regimes, these applications are reviewed in the final part. - Examines dynamic deformation and fracture of composite materials - Covers experimental, analytical and numerical aspects - Addresses important application areas such as aerospace, automotive, wind energy and defence, with a special section on sport applications

The solution is based on three-dimensional images captured with modern range sensors like e.g. high-resolution laser scanners. As result, objects are tracked and a detailed 3D model is built for each object and for the static environment. The performance is demonstrated in challenging urban environments that contain many different objects.
Book Synopsis Belief State Planning for Autonomous Driving: Planning with Interaction, Uncertain Prediction and Uncertain Perception by : Hubmann, Constantin
Download or read book Belief State Planning for Autonomous Driving: Planning with Interaction, Uncertain Prediction and Uncertain Perception written by Hubmann, Constantin and published by KIT Scientific Publishing. This book was released on 2021-09-13 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a behavior planning algorithm for automated driving in urban environments with an uncertain and dynamic nature. The algorithm allows to consider the prediction uncertainty (e.g. different intentions), perception uncertainty (e.g. occlusions) as well as the uncertain interactive behavior of the other agents explicitly. Simulating the most likely future scenarios allows to find an optimal policy online that enables non-conservative planning under uncertainty.

Book Synopsis Mobile laser scanning based determination of railway network topology and branching direction on turnouts by : Stein, Denis
Download or read book Mobile laser scanning based determination of railway network topology and branching direction on turnouts written by Stein, Denis and published by KIT Scientific Publishing. This book was released on 2018-06-26 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: GNSS is often inaccurate and satellite signals are not always available, which results in ambiguous situations. In order to reduce their negative effects on train-borne localization, this work proposes an approach for the detection of tracks, turnouts, and branching directions solely from 2d lidar sensor measurements. The experimental evaluation shows highly correct and complete results. In summary, these detections are sufficient to reduce ambiguity problems in train-borne localization.
Book Synopsis Compact Environment Modelling from Unconstrained Camera Platforms by : Schwarze, Tobias
Download or read book Compact Environment Modelling from Unconstrained Camera Platforms written by Schwarze, Tobias and published by KIT Scientific Publishing. This book was released on 2018-09-25 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile robotic systems need to perceive their surroundings in order to act independently. In this work a perception framework is developed which interprets the data of a binocular camera in order to transform it into a compact, expressive model of the environment. This model enables a mobile system to move in a targeted way and interact with its surroundings. It is shown how the developed methods also provide a solid basis for technical assistive aids for visually impaired people.
