Computer vision is probably the most exciting branch of image processing, and the number of applications in robotics, automation technology and quality control is constantly increasing. Unfortunately entering this research area is, as yet, not simple. Those who are interested must first go through a lot of books, publications and software libraries. With this book, however, the first step is easy. The theoretically founded content is understandable and is supplemented by many practical examples. Source code is provided with the specially developed platform-independent open source library IVT in the programming language C/C++. The use of the IVT is not necessary, but it does make for a much easier entry and allows first developments to be quickly produced. The authorship is made up of research assistants of the chair of Professor Ruediger Dillmann at the Institut für Technische Informatik (ITEC), Universitaet Karlsruhe (TH). Having gained extensive experience in image processing in many research and industrial projects, they are now passing this knowledge on. Among other subjects, the following are dealt with in the fundamentals section of the book: Lighting, optics, camera technology, transfer standards, camera calibration, image enhancement, segmentation, filters, correlation and stereo vision. The practical section provides the efficient implementation of the algorithms, followed by many interesting applications such as interior surveillance, bar code scanning, object recognition, 3-D scanning, 3-D tracking, a stereo camera system and much more.

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.

Maker Line est un capteur de ligne doté d'un réseau de 5 capteurs IR capable de suivre des lignes de 13 mm à 30 mm de largeur. L'étalonnage du capteur a également été simplifié. Il n'est pas nécessaire d'ajuster le potentiomètre pour chaque capteur IR. Il vous suffit d'appuyer sur le bouton de calibrage pendant 2 secondes pour accéder au mode de calibrage. Ensuite, vous devez faire glisser les capteurs sur la ligne, appuyer à nouveau sur le bouton et vous êtes prêt à partir. Les données d'étalonnage sont stockées dans l'EEPROM et restent intactes même lorsque le capteur est éteint. L'étalonnage ne doit donc être effectué qu'une seule fois, sauf si la hauteur du capteur, la couleur de la ligne ou la couleur de fond ont changé. Maker Line prend également en charge deux sorties : 5 sorties numériques pour l'état de chaque capteur indépendamment, ce qui est similaire au capteur IR classique, mais vous bénéficiez d'un étalonnage facile, et également une sortie analogique, où la tension représente la position de la ligne. La sortie analogique offre également une résolution plus élevée par rapport aux sorties numériques séparées. Ceci est particulièrement utile lorsqu’une grande précision est requise lors de la construction d’un robot suiveur de ligne avec contrôle PID. Caractéristiques Tension de fonctionnement : compatible DC 3,3 V et 5 V (avec protection contre l'inversion de polarité) Largeur de trait recommandée : 13 mm à 30 mm Couleur de ligne sélectionnable (claire ou foncée) Distance du capteur (hauteur) : 4 mm à 40 mm (Vcc = 5 V, ligne noire sur surface blanche) Taux de rafraîchissement du capteur : 200 Hz Processus d'étalonnage facile Types de sortie double : 5 sorties numériques représentent chaque état du capteur IR, 1 sortie analogique représente la position de la ligne. Prend en charge une large gamme de contrôleurs, tels que Arduino, Raspberry Pi, etc. Téléchargements Fiche de données Tutoriel : Construire un robot de suivi de ligne bon marché
