Computer Vision ist das wohl spannendste Gebiet der Bildverarbeitung und die Zahl der Anwendungen in der Robotik, Automatisierungstechnik und Qualitätssicherung nimmt stetig zu. Leider gestaltet sich der Zugang zu diesem Forschungsbereich bisher nicht einfach. Interessierte müssen sich zunächst durch viele Bücher, Publikationen und Software-Bibliotheken arbeiten.Mit dem vorliegenden Buch dagegen fällt der Einstieg leicht. Die theoretisch fundierten Inhalte sind gut verständlich dargestellt und werden durch viele Beispiele aus der Praxis ergänzt. Die abgedruckten und online verfügbaren Implementierungen sind in der Programmiersprache C/C++ mit der am Lehrstuhl entwickelten, plattformunabhängigen Open-Source-Bibliothek IVT erstellt. Die Verwendung der IVT ist dabei keine Voraussetzung, erleichtert jedoch wesentlich den Einstieg und ermöglicht schnell erste eigene Entwicklungen.Die Autorenschaft setzt sich aus Mitarbeitern des Lehrstuhls von Herrn Prof. Dr.-Ing. Rüdiger Dillmann am Institut für Technische Informatik (ITEC) der Universität Karlsruhe (TH) zusammen, die in vielen Forschungs- und Industrieprojekten umfangreiche Erfahrung in der Bildverarbeitung sammeln konnten und auch in der Lehre gelernt haben, dieses Wissen weiterzugeben.Im Grundlagenteil des Buches werden u. a. behandelt: Beleuchtung, Optik, Kameratechnik, Übertragungsstandards, Kamerakalibrierung, Bildaufbereitung, Segmentierung, Filter, Korrelation und Stereosehen.Im Praxisteil wird die effiziente Implementierung der Algorithmen vermittelt, gefolgt von vielen interessanten und erprobten Anwendungen wie Barcode-Leser, Stereokamerasystem, Sicherheitstechnik, Objekterkennung, 3D-Scannen, 3D-Tracking und vieles mehr.Mehr Infos:http://wwwiaim.ira.uka.de/computer-vision/

A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

Es ist möglich, den Cytron 25Amp 7-58 V High Voltage DC Motor Driver über PWM- und DIR-Eingänge zu steuern. Die Eingangslogikspannung reicht von 1,8 V bis 30 V und das Board ist mit einer Vielzahl von Host-Controllern (wie Arduino, Raspberry Pi, PLC) kompatibel. Wenn Sie den Motor nicht programmieren möchten, um ihn zu steuern, besteht die Möglichkeit, den Motorcontroller über einen Potentiometer (Geschwindigkeit) und einen Schalter (Richtung) zu steuern. Sie können den Motor auch schnell und bequem mit den onboard Testtasten und Motor Output-LEDs testen, ohne den Host-Controller anschließen zu müssen. Der Host-Controller kann mit dem Buck-Regler mit 5 V Ausgangsspannung betrieben werden. Dies ist insbesondere bei Hochspannungsanwendungen nützlich, bei denen keine zusätzliche Stromquelle oder Hochspannungsbuckregler benötigt werden. Dieser Motorcontroller verfügt auch über verschiedene Schutzfunktionen. Wenn der Motor blockiert oder Sie einen zu großen Motor angeschlossen haben, wird der Überstromschutz die Platine schützen und vor Beschädigung schützen. Wenn der Motor versucht, einen Strom zu ziehen, der höher ist als der Motorcontroller unterstützen kann, wird der Motorstrom auf den maximalen Schwellenwert begrenzt. Unterstützt durch den Temperaturschutz, hängt der maximale Strombegrenzungsschwellenwert von der Boardtemperatur ab. Je höher die Boardtemperatur, desto niedriger der Strombegrenzungsschwellenwert. Hinweis: Die Stromversorgung hat keinen Schutz gegen Rückwärtsspannung. Das Anschließen der Batterie in umgekehrter Polarität beschädigt den Motorcontroller unverzüglich. Features Bidirektionale Steuerung für einen gebürsteten Gleichstrommotor Betriebsspannung: DC 7 V bis 58 V Maximaler Motorstrom: 25 A Dauer, 60 A Spitze 5 V Ausgang für den Host-Controller (max. 250 mA) Tasten für schnelle Tests LEDs für den Zustand des Motorausgangs Dualer Eingangsmodus: PWM/DIR oder Potentiometer/Schalter-Eingang PWM/DIR-Eingänge kompatibel mit 1,8 V, 3,3 V, 5 V, 12 V und 24 V Logik (Arduino, Raspberry Pi, PLC, usw.) PWM-Frequenz bis zu 40 kHz (Ausgangsfrequenz ist auf 16 kHz festgelegt) Überstromschutz mit aktivem Strombegrenzung Temperaturschutz Unterspannungsabschaltung Lieferumfang  1 × MD25HV (Motor-Treiber-Board) 1 × Potentiometer mit Steckverbinder 1 × Kippschalter mit Steckverbinder 4 × Nylon-PCB-Stützen/Abstandshalter Downloads Datenblatt Beispielcode
