本論文主要是建立數位影像平台,建立CMOS Image Sensor 取像模組與網路通訊模組,使用Blackfin BF533 DSP 建立取像控制與影像處理演算法,進行影像前置處理,並依需求設定所需的影像資料類型與大小,使用網路通訊模組與TCP/IP通訊協定傳輸資料,節省資料傳輸時間,以建立一套PC控制多套影像模組,最後使用數位影像處理與橢圓辨識演算法在數位影像平台實作驗證。 This paper deals with the research on the digital image platform, It made CMOS image sensor photograph module and internet module. The main core of the system is Blackfin BF533 DSP,It made image control and digital image processing algorithm. The system of digital image platform is pre-processed to image.It can to set the image type and image size.Internet module transmit the image data,and reduce the time of transmit data. Internet protocol used TCP/IP protocol. Allow a personal computer can control many digital image platform. Finally the digital image platform can use these of digital image processing algorithm and ellipse system identification algorithm.
