【摘要】： 數(shù)字化陳展交互作為博物館陳展的有效手段,近幾年來,在博物館和展覽場館中的應(yīng)用已經(jīng)越來越深入和廣泛,各種交互設(shè)備和技術(shù)不斷涌現(xiàn),給用戶帶來良好的參觀體驗。一方面,為了提升展示效果,各種高逼真、大區(qū)域的展示設(shè)備被投入使用,而如何在具備大展示區(qū)域的陳展環(huán)境下進行方便、有效的交互,成為陳展交互領(lǐng)域的一個研究熱點。另一方面,陳展交互的實際應(yīng)用中,在滿足有效交互需求的前提下,也要求系統(tǒng)具有易于管理和維護、相對廉價以及方便使用等特點,容易進行推廣。 針對大展示區(qū)域的陳展交互方便性、有效性和相對廉價的需求,本文首先提出了一種面向大展示區(qū)域的陳展交互方法。用戶只需揮動手臂,而無需佩戴和操作任何輔助設(shè)備,通過自然手勢,實現(xiàn)方便的瀏覽和鑒賞。研究利用帶紅外濾鏡的相機進行動作捕捉,排除投影圖像干擾,降低處理難度。研究采用光流法處理運動圖像序列,得到運動顯著點的運動方向和瞬時速度,生成交互指令。以背投幕下敦煌壁畫展示為例,實現(xiàn)對高精度壁畫的陳展交互。 針對降低展覽場館對交互設(shè)備管理、維護難度的需求,本文也提出了一種基于手持設(shè)備的陳展交互方法。目前智能手機、PDA等手持設(shè)備較為普及,而且具有良好的展示效果和易操作性,因此比較適合用來作為交互和展示平臺。為了減少手持設(shè)備平臺相對PC平臺的性能限制,研究利用FAST方法快速完成場景圖像特征提取,并采用特征跟蹤策略加速處理,提高系統(tǒng)實時性。同時,為了提高系統(tǒng)的魯棒性,研究使生成的特征描述具有對尺度、旋轉(zhuǎn)和光照不變性。
[Abstract]:Digital display interaction as an effective means of museum exhibition Chen, in recent years, in museums and exhibition venues in the application of more and more in-depth and extensive, a variety of interactive equipment and technology continue to emerge, to bring users a good experience of the visit. On the one hand, in order to improve the display effect, a variety of high-lifelike, large-scale display equipment has been put into use, and how to conduct convenient and effective interaction in the Chen exhibition environment with large display area has become a research hotspot in the field of Chen exhibition interaction. On the other hand, in the practical application of Chen Zhan interaction, under the premise of satisfying the requirement of effective interaction, the system is required to be easy to manage and maintain, relatively cheap and convenient to use, so it is easy to be popularized. Aiming at the demand of convenient, effective and relatively cheap display interaction in large exhibition area, this paper first proposes a new interactive method for large display area. Users only need to swing their arms, without wearing and operating any auxiliary devices, through natural gestures to achieve convenient browsing and appreciation. In this paper, a camera with infrared filter is used to capture the motion, eliminate the interference of the projection image, and reduce the processing difficulty. In this paper, the moving image sequence is processed by optical flow method, and the motion direction and instantaneous velocity of the salient point of motion are obtained, and the interactive instructions are generated. Take Dunhuang mural display as an example to realize the interactive exhibition of high-precision murals. In order to reduce the difficulty of interactive equipment management and maintenance in exhibition venues, a new interactive method based on handheld devices is proposed in this paper. At present, handheld devices such as smart phone and PDA are popular, and have good display effect and easy operation, so they are more suitable to be used as interactive and display platform. In order to reduce the performance limitation of handheld device platform relative to PC platform, the feature extraction of scene image is accomplished quickly by using FAST method, and the feature tracking strategy is adopted to accelerate the processing to improve the real-time performance of the system. At the same time, in order to improve the robustness of the system, the generated feature description has the invariance of scale, rotation and illumination.
