中文摘要： 城市化进程的热潮给城市管理方式提供了新的机遇和挑战。然而，相关信息的缺乏使得紧急事件的应急响应变得非常困难。这种情况下，大众通过提供影像资料、事件地点等信息参与到事件处理中变得十分有价值。但是，现有系统多关注智能城市建设，却忽略了大众可以贡献力量这一重要因素。本项目通过志愿者地理众包视频，利用智能手机和无线网络，使大众便捷有效的参与到智能城市的建设和管理中。本项目考虑地理众包视频实时参与、规模可变等特点，紧紧围绕用户生成的多媒体数据、地理位置和观测方向等信息的采集，众包模式下参与社交媒体的分享与反馈等问题，重点针对创新性的图片、视频和地理信息采集与传播技术，多样化的众包方法和用户奖励机制，设计并实现一个集成智能手机与嵌入式传感器的信息采集及云处理系统。此项目将对应急响应、灾害管理、城市管理与规划等生活不同领域有着深远的影响，研究成果对科研和实体经济有着非常重要的理论研究意义和实际应用价值。

英文摘要： The current trend of urbanization, where a significant fraction of the population continues to migrate to cities, is providing both challenges and opportunities in the way that urban environments are managed. For example, responding to an emergency (e.g., earthquake) can be challenging because of a lack of information (which parts of a city are affected? Which streets are still available for relief trucks?). Sometimes there may be minor problems such as a tree that fell into a street. In such situations it can be extremely valuable to get the participation of citizens in the area who can provide images, videos, and location information. Today's advanced technology has the potential to provide useful information from volunteers to significantly improve the effectiveness of how a city is managed. However, while there is considerable interest in Smart Cities, citizen volunteers are not a central part in most existing systems. Our proposal focuses on empowering citizens to participate in these processes and enable smart urban management. Specifically, we focus on the compelling combination of ubiquitous smartphone availability and high speed wireless connectivity that enables citizens to be in contact with their city government easily and efficiently. We propose to design a system for active citizen participation in smart urban management. In the technical dimension we will use mobile platforms (smartphones) with their embedded sensors so that users can contribute and obtain (a) user-generated content such as multimedia (images and videos) and (b) location- and direction information (geographic or GIS information). In the user dimension the system will incorporate (c) crowd-sourcing capabilities that allow volunteer participation, social media sharing and feedback. The system will be designed for real-time and scalable operation to improve urban living. The proposed system requires strong expertise in multimedia management, GIS and geographic technology, social media and information systems. The project team has very strong backgrounds and has performed pioneering work in all these areas. The intellectual merit of the proposed work lies in its use of cutting-edge mobile devices, state-of-the-art algorithms and methods to create an overall system with easy-to-use apps and cloud/server applications. We will investigate novel image, video and geographic information acquisition and dissemination techniques, various crowd-sourcing methods and user incentive mechanisms. We will combine these capabilities into an overall, integrated system. The solution will have a broad impact on different urban living scenarios ranging from emergency response and disaster management, to crime and accident management, traffic optimization, etc. The results of the work will be made available to researchers, city and government entities and industry via publications and the distribution of the developed software system.
