【摘要】： 数字化陈展交互作为博物馆陈展的有效手段,近几年来,在博物馆和展览场馆中的应用已经越来越深入和广泛,各种交互设备和技术不断涌现,给用户带来良好的参观体验。一方面,为了提升展示效果,各种高逼真、大区域的展示设备被投入使用,而如何在具备大展示区域的陈展环境下进行方便、有效的交互,成为陈展交互领域的一个研究热点。另一方面,陈展交互的实际应用中,在满足有效交互需求的前提下,也要求系统具有易于管理和维护、相对廉价以及方便使用等特点,容易进行推广。 针对大展示区域的陈展交互方便性、有效性和相对廉价的需求,本文首先提出了一种面向大展示区域的陈展交互方法。用户只需挥动手臂,而无需佩戴和操作任何辅助设备,通过自然手势,实现方便的浏览和鉴赏。研究利用带红外滤镜的相机进行动作捕捉,排除投影图像干扰,降低处理难度。研究采用光流法处理运动图像序列,得到运动显著点的运动方向和瞬时速度,生成交互指令。以背投幕下敦煌壁画展示为例,实现对高精度壁画的陈展交互。 针对降低展览场馆对交互设备管理、维护难度的需求,本文也提出了一种基于手持设备的陈展交互方法。目前智能手机、PDA等手持设备较为普及,而且具有良好的展示效果和易操作性,因此比较适合用来作为交互和展示平台。为了减少手持设备平台相对PC平台的性能限制,研究利用FAST方法快速完成场景图像特征提取,并采用特征跟踪策略加速处理,提高系统实时性。同时,为了提高系统的鲁棒性,研究使生成的特征描述具有对尺度、旋转和光照不变性。
[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.
