遠端監控之視覺系統研製

Abstract

隨著網路的發達與普及，遠端監控的應用也就越來越廣泛，但在現今社會的保全系統仍有不足的情況下，加上保全人員的費用昂貴，不是一般民眾所負擔的起的，將影像擷取與網路技術相結合，配合影像分析與處理，便能以低廉的成本，達到監控保全的目的。 本論文結合了影像擷取、影像處理與網路控制，研發製作出一套遠端監控系統，其中，將重點放在影像擷取及分析、處理方面。採用MICROSOFT所提供MSDN的函數，以電腦為工作平台，利用電腦的USB介面，加上影像擷取裝置，例如攝影機、數位相機等，來進行影像擷取。分析、處理方面做到擷取影像的存檔、壓縮，並具有移動物偵測及自動警報通知的功能，當有人入侵設定的監控範圍時，警報系統將被啟動並透過電子郵件通知使用者，最後，與網路傳輸相結合，將即時影像自動送至遠方，並讓使用者能夠透過簡便的操作，不受時間、地點的影響，透過瀏覽器的網頁，觀看伺服端監控的結果畫面。

As the network was developed and popular, the application of remote monitoring system is more and more broad-spectrum. Not only the security system in our society is still deficient but the cost of private security service is expensive as well. Both of them could not be afforded by the common people. Now it can cost us few to achieve the aim by combining the image capture, and network technique together with operating in coordination of the analysis and the image processes. The real-time remote monitoring system, which combines image captures, image processes and network control is proposed in this thesis. Thereamong, We focused on the image captures and processes. According to the MSDN functions which were afforded by Microsoft and USB(Universal Serial Bus), we can use the digital camera or CCD ones to capture images. In the parts of image analysis and image process, we can compress and save the image/video files and act motion detection to give the alarms. When someone intrudes the areas we were monitored, the system will be set in motion and sent the e-mail to the users. Finally, we attached the image transmission trough internet to our system. Let the users observe the condition of monitoring system by browser without any limits.
