本論文將針對較低硬體要求的嵌入式資訊裝置,以軟體設計的方式撰寫網際網路通訊協定組的各項分層,達到不需要作業系統也能夠透過網際網路來傳輸資料,以及引入即時串流傳輸技術使監視的影像能夠即時的傳送至用戶端。實現的方式,首先先將攝影機所拍攝的畫面,進行影像壓縮,再利用即時串流傳輸技術將壓縮後的影像資料封裝並且切割成適合在網際網路上傳輸的封包大小,最後再藉由本論文所設計的網際網路通訊協定組的程式將影像資料透過網際網路傳送至遠端使用者以即時串流的方式觀看影像。
同時本論文也將針對在網際網路不允許的環境下,設計使用儲存的方式錄製監控的影像,並且利用影像運動偵測法來篩選錄製的影像,使系統能在有限的儲存空間達到最高的錄影效率。影像運動偵測法可從攝影機所拍攝的畫面裡得知是否有移動物體的產生,進而決定系統是否要啟動錄影的機制。
In this paper, by software designed of the internet protocol layers for low grade embedded device, without operating system can also be reached via the Internet to transmit data, and introduction of real-time transport protocol technology to enable real-time surveillance video can be transmitted to the client at real-time.
Implementation approach, first compression image after captured of camera, and uses real-time transport protocol technology to the compressed image data package and cut to fit the Internet transmission of the packet size. Finally, uses by software designed of the internet protocol program for image data sent over the Internet to remote users a way to watch live streaming video.
At the same time, the paper is designing recorded surveillance video by storing in the internet is not allowed, and employing to sift out from recording image by motion detection, it can make the system to achieve maximum efficiency of recording in limited space. The method of motion detection can detect whether the objects is moving or not to decide whether the system is start to recording image or not.
