Automated optical inspection system for digital TV sets

Abstract: This article proposes a real-time test and verification system for full-reference automatic image quality assessment and verification of digital TV sets. Digital camera is used for acquisition of the TV screen content in order to ensure quality assessment of the content as perceived by the user. Test has been executed in three steps: image acquisition by camera, TV screen content extraction and full-reference image quality assessment. The TV screen content is extracted from the captured image in two steps: det… Show more

“…drawing multiple lines simultaneously, which is useful for producing zooming moves on the touchscreen. Stimulation board can be applied to design a system for automated verification of devices with touchscreens based on the similar concept as the previous work of the authors on implementation of the system for automated verification of television sets [15], [16]. The concept of the system is given in Fig.…”

“…Outro exemploé apresentado em [10], onde utiliza-se um sinal de referência misturado com um sinal de erro através de software para encontrar problemas na interação entre hardware e software. Alguns trabalhos de detecção de falhas propõem um sistema de inspeção automática baseado na análise da imagem [11], [12], [13], [14], [15]. Estes sistemas fornecem um diagnóstico da TV (ou monitor) inspecionados através da análise da informação de saída da tela, utilizando esta informação para encontrar falhas de software ou hardware que gerem defeitos na imagem final.…”
