摘? 要: 傳統的虛擬家具展示操作流程復雜,且在進行家具角度變換時成像模糊,為解決這一問題,提出基于用戶體驗的家具虛擬展示設計。利用3D Studio MAX建模軟件在開發平臺上確定各個點的坐標,根據各個點的位置變化建立模型結構,在對數字正射影像數據進行校準的基礎上疊加計算數字高程數據,生成具有視差的左右立體圖像對,最后建立原型節點機制,引入虛擬現實建模語言動態映射技術,完成基于用戶體驗的家具虛擬展示設計。通過對用戶進行任務測試的結果可知,使用基于用戶體驗的家具虛擬展示成像效果清晰度為5 MP,比傳統方法的成像效果清晰度高出4 MP,驗證了設計的基于用戶體驗的家具虛擬展示的有效性。

Abstract: The design on furniture virtual presentation based on user experience is proposed in view of the facts that the traditional virtual furniture display operation process is complex, and the imaging is fuzzy when the angle of furniture is changed. The 3D Studio MAX modeling software is used to determine the coordinates of each point on the development platform and build the model structure according to the change of position of each point. The superposition calculation of digital elevation data is executed on the basis of calibrating the digital orthoimage data to generate left and right stereo image pairs with parallax. Finally, the prototype node mechanism is established and the virtual reality modeling language (VRML) dynamic mapping technology is introduced to complete the design of furniture virtual presentation based on user experience. The results of task test on users show that the definition of imaging effect of furniture virtual presentation on the basis of user experience is 5 MP, which is 4 MP higher than that of the traditional method. The test results verify the effectiveness of furniture virtual presentation designed on the basis of user experience.
Keywords: furniture virtual presentation; user experience; 3D modeling; VRML dynamic mapping; stereo image pair generation; design research

隨著生活質量的提高,人們對于家具的選擇也有著更高的要求。國內外家具市場發展迅猛,信息化技術在其中有著不可或缺的作用,大多數的家具軟件最初主要應用在設計、制圖方面。由于家具本身種類多、體積大等特點,展廳的面積有限而不能將所有的家具都呈現在顧客面前[1]。為了更好地展示產品,近年來家具軟件逐漸趨近于展示方面的發展,主要以圖片或是Flash動畫為主要展現方式,逐漸融入了人機互動、三維虛擬現實等技術,但是由于家具虛擬展示是剛剛興起的與高科技結合的一個項目,在用戶體驗方面還不是特別完善,操作流程繁瑣復雜,且在進行家具角度轉換時成像模糊,用戶體驗差。……
