In this paper, with Unity3d engine as the core, tourism system is expanded the development, combined with the tourism information overlay function of Ctrip Travel, the attractions sharing function of Baidu Map, and the community function of Footprint. The purpose involves design, development and optimizing debug of techniques, such as network communication, UI interaction, cross-platform calls, database access and etc. The main goal of this paper is to provide internal visit narrative community service in limited and fixed scenic area and turning the corresponding service object by mass of visitors to the visitors of scenic spot, and to make the function of App specific, simple and explicit.展开更多

With the development of modernization, the number of person who inherits or understands the intangible cultural heritage is dwindling. Hence, we need a new form to inheritance this art urgently. Based on augmented reality technology, we achieve the real-time calculation of image position and angle, the exhibition of the corresponding virtual scene in this paper. Users can achieve the virtual interaction in reality, thus, multi-dimensional experience of paper-cut is provided for users.展开更多

A physical model of the FSM system is derived based on first principles, describing the dynamics and coupling between the inputs and outputs of the FSM system. The physical model is then represented in a state-space form. Unknown parameters in the state-space model are identified by the subspace identification algorithm, based on the measured input-output data of the FSM system. The accuracy of the state-space model is evaluated by comparing the model estimates with measurements. The variance-accounted-for value of the state-space model is better than 97%, not only for the modeling data but also for the validation data set, indicating high accuracy of the model. Comparison is also made between the proposed dynamic model and the conventional static model, where improvement in model accuracy is clearly observed. The model identified by the proposed method can be used for optimal controller design for closed-loop FSM systems. The modeling method is also applicable to FSM systems with similar structures.展开更多
