ABSTRACT
This chapter deals not only with the technical aspects of illumination and image recording techniques but also with image processing and computer vision processes relevant to the optical measurement and testing technique and their implementation in typical measurement and testing tasks. It describes several software products that are available commercially for image processing and computer vision. Most of the microelectromechanical systems or microoptoelectromechanical systems available have been created using the combination of electronic, optical, and mechanical functional groups. The elementary task of digital image processing and computer vision is to record images, to process/improve and analyze the image data by using appropriate algorithms, to supply results derived from them, and to interpret these results. In addition to requiring the knowledge of the theory of digital image processing, it becomes immediately clear from the scenario that expertise in the fields of light physics, optics, electrical engineering, electronics, and computer hardware and software is also necessary.
