【摘要】：目前，多點觸摸技術已經(jīng)在多種觸摸識別系統(tǒng)中得到了應用，如使用電阻或電容式觸摸屏的小型移動設備，但是將多點觸摸技術與桌面GIS (GeographyInformation System)結合使用的應用很少，絕大多數(shù)仍然使用鼠標和鍵盤進行操作。論文所依托的項目旨在提高人機交互特性，開發(fā)一個可通過多點觸摸手勢直接操作的桌面GIS。針對項目要求提出一種研究方案：首先使用基于光學和計算機視覺的紅外多點觸摸技術搭建系統(tǒng)硬件平臺，然后讀取包含觸點對象的一系列視頻幀并進行圖像處理，提取觸點輪廓，計算輪廓中心坐標，完成追蹤觸點移動軌跡，通過TUIO (Table-Top User Interfaces Objects)協(xié)議傳遞觸點信息，最后分析觸點移動軌跡的形狀識別有效交互手勢并通過MapX實現(xiàn)操作GIS。作者參與完成該項目的這三個部分，并在所做的研究工作基礎上完成了畢業(yè)論文。 論文主要分成三個部分：第一部分介紹紅外多點觸摸平臺上觸點追蹤算法的實現(xiàn)過程，主要包括視頻流捕獲，圖像處理算法，觸點輪廓提取，追蹤觸點，以及數(shù)據(jù)通信等過程；第二部分定義了6種多點觸摸手勢，并分析了手勢對應的狀態(tài)轉(zhuǎn)移模型，然后在對觸點移動軌跡進行分類的基礎上實現(xiàn)了多點觸摸手勢識別方法，最后詳細闡述了由MapX實現(xiàn)GIS的具體步驟和有效手勢對GIS的操作結果；第三部分給出了多點觸摸GIS平臺的系統(tǒng)架構，包括多點觸摸GIS平臺的各個組件以及所有組件的搭建過程和工作流程，最后對鼠標點擊操作與手指觸摸操作進行了分析對比，并分析了系統(tǒng)實驗結果。 本項目給出了一個紅外多點觸摸的GIS，，用戶可通過多點觸摸手勢直接操作GIS，完成典型的GIS功能。該系統(tǒng)相對于傳統(tǒng)的GIS具有更好的人機交互特性和用戶體驗。
[Abstract]:At present, multi-touch technology has been applied in many kinds of touch recognition systems, such as small mobile devices using resistor or capacitive touch screen, but the application of combining multi-touch technology with desktop GIS (Geographic Information system) is rare. The vast majority still operate using the mouse and keyboard. The purpose of this paper is to improve the human-computer interaction and to develop a desktop GIS which can be directly operated by multi-touch gestures. To meet the requirements of the project, a research scheme is proposed: firstly, the hardware platform of the system is built with infrared multi-touch technology based on optics and computer vision, and then a series of video frames containing contact objects are read and processed. The contours are extracted, the center coordinates of the contours are calculated, and the contact trajectory is traced. The contact information is transmitted through the Table-Top user Interfaces objects protocol. Finally, the effective interactive gesture recognition of the contact trajectory is analyzed and the GISs operation is implemented through MapX. The author participated in the three parts of the project and completed the graduation thesis on the basis of the research work done. The thesis is divided into three parts: the first part introduces the realization process of contact tracking algorithm on infrared multi-point touch platform, including video stream capture, image processing algorithm, contours extraction, tracing contact, and data communication. In the second part, six kinds of multi-touch gestures are defined, and the corresponding state transition model is analyzed, and then the multi-touch gesture recognition method is implemented on the basis of classifying the contact trajectory. Finally, the concrete steps of GIS implementation by MapX and the results of GIS operation by effective gestures are described in detail. The third part gives the system architecture of multi-touch GIS platform. It includes the components of multi-touch GIS platform and the construction process and workflow of all components. Finally, the mouse click operation and finger touch operation are analyzed and compared, and the system experimental results are analyzed. In this project, a GIS-IR multi-touch system is presented, which can be directly operated by multi-touch gestures to complete the typical GIS functions. Compared with the traditional GIS, the system has better human-computer interaction characteristics and user experience.
