Abstract
Cílem této bakalářské práce je vytvořit automatizovaný systém optické detekce vad dlouhohrajících gramofonových desek. Je zde rozebíráno, jakým způsobem a za jakých podmínek lze provést optickou kontrolu desky a následné zpracování s vyhodnocením. V rámci práce byly provedeny experimenty s osvětlením snímaného vzorku a jeho vlivu na kvalitu kamerou nasnímaných dat. Na závěr jsou zde diskutovány možnosti využití tohoto systému ve výrobním provozu. Veškeré operace s obrazovými daty jsou prováděny pomocí programu v LabView.
The aim of this work is to create an automated optical detection of defects long-playing phonograph records. Firstly it will explain how and what conditions the optical control of them may be performed along with processing and evaluation. In this work experiments were carried out with the lighting of the scanned sample and its impact on the quality of the camera scanned data. In conclusion the posibilities of this system on the factory floor are discussed. All operations of image data were performed using LabView.
