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.

De Elektor Super Servo Tester kan servo's aansturen en servosignalen meten. Hij kan tot vier servokanalen tegelijkertijd testen. De Super Servo Tester wordt geleverd als bouwpakket. Alle onderdelen die nodig zijn om de Super Servo Tester in elkaar te zetten zijn inbegrepen in de set. Het bouwen van de kit vereist enige basisvaardigheid met solderen. De microcontroller is al geprogrammeerd. De Super Servo Tester beschikt over twee bedrijfsmodi: Control/Manual en Measure/Inputs. In de modus Control/Manual genereert de Super Servo Tester besturingssignalen op zijn uitgangen voor maximaal vier servo's, of voor de flight controller of ESC. De signalen worden ingeregeld door de vier potentiometers. In de modus Measure/Inputs meet de Super Servo Tester de servosignalen die op de ingangen zijn aangesloten. Deze signalen kunnen afkomstig zijn van bijvoorbeeld een ESC, een flight controller, of de ontvanger, of een ander apparaat. De signalen worden ook naar de uitgangen geleid om de servo's of de flight controller of ESC aan te sturen. De resultaten worden op het display weergegeven.

Most people are increasingly confronted with the applications of Artificial Intelligence (AI). Music or video ratings, navigation systems, shopping advice, etc. are based on methods that can be attributed to this field. The term Artificial Intelligence was coined in 1956 at an international conference known as the Dartmouth Summer Research Project. One basic approach was to model the functioning of the human brain and to construct advanced computer systems based on this. Soon it should be clear how the human mind works. Transferring it to a machine was considered only a small step. This notion proved to be a bit too optimistic. Nevertheless, the progress of modern AI, or rather its subspecialty called Machine Learning (ML), can no longer be denied. In this book, several different systems will be used to get to know the methods of machine learning in more detail. In addition to the PC, both the Raspberry Pi and the Maixduino will demonstrate their capabilities in the individual projects. In addition to applications such as object and facial recognition, practical systems such as bottle detectors, person counters, or a “talking eye” will also be created. The latter is capable of acoustically describing objects or faces that are detected automatically. For example, if a vehicle is in the field of view of the connected camera, the information 'I see a car!' is output via electronically generated speech. Such devices are highly interesting examples of how, for example, blind or severely visually impaired people can also benefit from AI systems.
