摘要

近來融合觀賞者肢體動作於作品之數位互動藝術創作方興未艾，經由攝影機與運算設備整合預置影像動畫和實際人物，交錯時空和虛實併陳的互動裝置系統，亟需有核心的影像處理和定位合成的專用模組，而在虛擬實境及虛擬攝影棚運用效能較好的主機做去背及背景融合運算，不但成本較高，軟硬體的運用彈性上也不敷數位互動藝術便於展場組裝需求。
本研究基於使用Webcam於物體運動偵測系統的基礎，運用背景偵測的演算及空間定位設計，為數位互動藝術相關設計，設計並製作了一套稱為影像整合與開發模組(IIDM)簡便實用的程式組件。IIDM原型的主要模組曾實際配合國立台中市文化局互動科技創作展－秭器東來中的「神遊汴梁」作品，將位於作品前之觀賞者消除背景後，帶入中國名畫「清明上河圖」中，使觀賞者猶如進入清明上河圖中。經此實際運用驗證，我們對IIDM再增置空間定位演算，處理影像物件與虛擬場景中動畫物件碰撞問題及不同軸向運動處理的功能，整體而言IIDM可供數位互動藝術創作者作為核心工具，降低實作上的技術障礙，期使創作者創意得以容易發揮。

Recently, it is a new fashion that audiences’ body movements have been integrated into the interactive digital art. These interactive art systems can simultaneously perform virtual and real scenes indifferent time spaces. in order to integrate audiences’ body movements into pre-set animations by cameras and computer servers, these core models for image processing, object locating and combining are the required functions of the system. Furthermore, it would be very time-consuming when interactive art creators use high-end computers to remove backgrounds from audiences and combine their body movements with new backgrounds in real-time. Besides, the flexibilities of these software and hardware are not convenient enough to meet the needs of being quickly assembled in exhibitions of interactive digital art.
From the above discussion of the relevant works of interactive digital art, this study implemented a set of simple and economical models -- Image Integration and Development Module(IIDM), which are based on a motion detection system with webcam and algorisms for background detecting, removing, object locating and combining. IIDM had been adopted by a work of interactive digital art called “Ramble in Bianliang City (the capital of Northern Song Dynasty)” from “Purple Breeze Comes from the East” series in Interactive Art Exhibition hosted by Cultural Affair Bureau of Taichung City, Taiwan. In “Ramble in Bianliang City”, after removing the background of one audience’ image which captured by webcam, this system combined this audience’s image of body movements with a famous Chinese picture -- “Along the River During the Ch'ing-ming Festival” in real-time, so that the audience looked and felt like rambling along the river. IIDM also solved the problem of the collisions between webcam-captured objects and virtual objects in the scenes of animations and the problem of different axial movements.
Based on above practical application, IIDM proved that it could be adopted as a core technology for interactive art creator to reduce the technical obstacles for implement. Therefore, better creativities could be supported well with IIDM.
