To provide personalized guiding service for visitors in the museum, a new museum guide system based on mobile visual search is presented. It allows visitors access information about objects of interests by taking pictures with the camera of a mobile phone. The key contribution is an improved framework of mobile visual search by considering the performance differences of various mobile phones, which can recognize large-scale objects on the remote server, and perform real-time object recognition with the mobile phone in a given region. Compared with existing guide systems, our system is more user-friendly, and provide more comprehensive information. In addition, it does not need to install any equipment and can be widely used in the museum guide applications. Experimental results show the feasibility and practicality of the proposed system.%为了对游客的参观过程提供个性化导览服务,使游客可以通过手机拍照的方式获取展品的相关资讯.提出一个基于移动视觉搜索技术的博物馆导览系统.针对手机性能的差异性,提出一种改进的移动视觉搜索系统的框架,使得系统既能在服务器端对海量展品进行识别,又能在手机端对特定区域内展品实时识别；并基于这一框架实现了一个原型系统.与现有的导览系统相比,文中系统的交互方式更加人性化,提供的展品信息更丰富、全面,且无需在馆内安装任何辅助设备,能够更广泛地适用于博物馆导览.实验结果证明了该系统的可行性和实用性.
