摘要

在以往的研究創建了虛擬實境 (Virtual Reality) 的家具展示系統，本論文建立了一個擴增實境 (Augmented Reality) 家具客製化系統。本研究擴增實境家具客製化系統相較於虛擬實境的家具展示系統增加了真實性。本研究基於虛擬實境的家具展示系統，增加了立體視覺、擴增實境、遮蔽演算以及家具客製化，建立一個擴增實境家具客製化系統。
本研究的擴增實境家具客製化系統允許使用者改變家具的尺寸以及材質去創建一個客製化的虛擬家具。使用傳統的標記追蹤方式在真實環境中展示客製化的虛擬家具。使用視差圖演算以及grabcut演算，搭配物體在左右視圖中的關係來處理遮蔽演算。使用立體視覺之頭戴式顯示器 (Head-Mounted Display) 來展示客製化的虛擬家具。並建立Server & Client減少演算時間。
人因測試結果顯示，受測者認為相較於虛擬實境的家具展示系統，擴增實境家具客製化系統增加了真實性。並認為本研究之系統尺寸變換精確、家具材質清楚呈現。相較於虛擬實境的家具展示系統，受測者更喜歡使用擴增實境家具客製化系統。

Prior studies created virtual reality furniture display systems. This thesis creates an augmented reality furniture customization system. This study increases the realism of a virtual reality furniture display system to create an augmented reality furniture customization system. This thesis adds stereo vision, augmented reality, occlusion, and customization functions to a virtual reality furniture display system to create an augmented reality furniture customization system.
The augmented reality furniture customization system allows users to change furniture dimensions and materials to create customized virtual furniture, uses a traditional marker-based tracking method to display customized virtual furniture in real scenes, uses a disparity map, a grab-cut method, and relationships between objects in left-view and right-view images to handle occlusions, uses a stereoscopic head-mounted display to display customized virtual furniture in real scenes, and uses a client-server architecture to reduce computing time.
User-test results show that subjects think the augmented reality furniture customization system increases realism, compared to a virtual reality furniture display system, changes furniture dimensions accurately, and displays furniture materials clearly. User-test results show that subjects prefer using the augmented reality furniture customization system, compared to a virtual reality furniture display system.
