    Abstract: 本計畫主要的目標是提供一個透過網路並且可以隨時隨地監控家中狀況的3D 影 像即時監控系統,這個系統所帶來的好處是可以只使用一個螢幕來監看家中不同 角落的位置,比起一般傳統的監視系統,如果要同時進行多點的監視,就需要多 個螢幕來達到這樣的目的,對於一般使用者而言,並不太適用;故我們將此系統 設計在一般可提供網路通訊的手機上,配合可以調整方位的3D 監控系統,讓普 羅大眾都可以使用具有網路通訊能力的行動裝置來確保家中平安。 在這個計畫中,我們將先提供使用者一個2D轉3D的監視系統,提供使用者體驗 一個不同於以往的監視系統,進而發展到自由視角的監視系統,以提供使用者全 方位監視為目的,為了能在運算能力較差的設備上提供使用者服務,我們針對即 時影音資料傳輸的特性為前提,提供與建立一個包含運算能力、傳輸能力以及儲 存能力的雲端架構,這個架構為了因應即時影音多媒體的資料傳輸,對於某些部 分我們將給予改善,比如說儲存部分只使用快取記憶體而不使用硬碟;另外一方 面我們的網路環境假設是在Ad-Hoc環境下,因此我們對電力的考量也做了深入的 考量,我們希望能夠讓每一個裝置都能夠延長服務時間,以確保整體影音資料的 傳輸品質。
    The purpose of this plane is to provide a 3D and real-time video system for monitoring the state of home through Internet anytime anywhere. The advantages of this system is to monitor many different spaces and nooks in a house by a monitor only. But there are many monitors are needed to show many different spaces at the same time with the method of tradition. It is not suitable for common user whose device is a cell phone only. Hence, we design the system base on a mobile communication system with the algorithm of 3D image system to monitor the state of home. By this system, we can rotate the image to look at home in a little monitor only and ensure the safety. At the first, we will provide a 2D to 3D conversion system of security monitor in this project and make user learn different experience with this system. We develop a free viewpoint monitor system to achieve full range monitor. We create a clouding computing architecture include calculation, transmission and storage system and make it serve the users with mobile device of lack of computing power. We optimize parts of this architecture to make it can support video as real time streaming. For example, we use cache memory as storage part rather than hard disk. In the other hand we propose our experiment environment based on ad-hoc network so the problem of power usage should be presented. We hope the service hours can be extended in every devices to guarantee the quality of video transmission.
