    摘要: 本文探討影像分析技術，似應用於民生工業的液體充填高度檢測系統。在一般日常用品上，例如飲料、清潔劑、除蟲劑等等產品，對於夜體充填的處理，則被視爲一項重要的品管項目，尤其液體在高壓裝罐的過程中，液體水位過高，瓶罐會有被爆穿的危險；液體水位過低，將使消費者有不良的產品印象，因此，檢測充填高度，則成爲一項重要的課題。
    文中所設計的自動檢測系統，採用類比攝相機，以每秒最高二十張影像的擷取速度，檢視生產線上的作業進度，並收集充填高度資料，進行即時品管監控。而此系統採用National Instruments Corporation的影像擷取卡(PCI-1408)，將類比影像轉換爲數位影像，搭配LabVIEW程式語言和NI-IMAQ影像處理軟體，針對連續充填影像進行檢測，以建立品管資料庫，作系統分析調整。


    In-line gauging application of liquid filling process was implemented in this work. Cans and bottles filled with liquid exist in various household products. Liquid level of the bottle is one of the important quality attributes for the inspection. Moreover, exceeding liquid level in pressure bottle can cause explosion and danger to people. The task of this study was to implement vision-gauging methods to automatically inspect the liquid levels in the filling process. The inspection technique used edge detection to identify significant boundaries in the image. The result of an edge detection operation was a set of points describing the locations of the bottle cap and liquid level edges identified in the image. The bottle cap and the liquid level in pixel coordinate were recorded by the edge detection scheme. The distance between the edges of bottle cap and liquid level was calculated and recorded in an external file for statistical quality control. National Instruments LabVIEW and IMAQ Vision software were utilized as development tools in realization of the work. Moreover, because of the diverse tools within LabVIEW, other types of I/O such as motion control, instrument control, and data acquisition were easily integrated into the application.
