本論文主要是開發設計一智慧型網路攝影機，以Blackfin DSP 為核心，配合所設計的CMOS Image Sensor 取像模組和網路通訊模組，建立取像控制功能及數位影像處理演算法。以網路做為傳輸的介面，透過HTTP 網頁瀏覽器與攝影機進行通訊，並經過網路攝影機內部的前置處理，搭配橢圓辨識，將辨識過後的資訊回傳，提升傳輸效能。本網路攝影機體積小、解析度高、速度快，同時具備數位影像處理功能，一台PC 可控制多套網路攝影機，成本低，可做分散控制，適合和工業應用。 This paper is mainly aimed at developing an intelligent Ethernet camera which combines designed CMOS image sensor photograph module and internet module to implement image capture control and digital image processing algorithm based on Blackfin DSP. With Ethernet interface, the camera communicate via the web browser, by inner pre-processing and ellipse identification, all indentified information can be reported to increase the transmission efficiency. This Ethernet camera is tiny and with high resolution. Also, it can be used for digital image processing. One PC can command many Ethernet cameras simultaneously which leads to low cost and nice decentralized control. All in all, it’s suitable for industrial application.
