However, it lacks efficiency in using of Google Map Street View system due to its discrete nature.We have to keep clicking the ”arrow” continuously so as to move forward.When we want to move a long distance, the process of repeated arrowclcking become very boring and troublesome. Hyperlapse provides another ways to view a lot of street view images. Nevertheless, its viewing experience is also not comfortable and tedius in a long time. In this thesis, we provide a virtual tour video generator system. Users select effects they want to view. After making a low resolution post-production pre-view video, the systme will generate a high-resolution street view video which includes all effects selected by user. Hence, the video can be used for pre- travel or tripreview. In addtion, user evaluation show that the proposed method increases the satisfication of users in viewing the street view sequence.口試委員會審定書ii 誌謝iii 摘要iv Abstract v 1 Introduction 1 2 Related Work 4 2.1 Constant Rate Street View Video . . . . . . . . . . . . . . . . . . . . . . 4 2.2 Navigation System with Street View . . . . . . . . . . . . . . . . . . . . 4 3 Street View Based Animation Creation 5 3.1 System Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 3.2 Preview Video System . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 3.2.1 User Input . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 3.2.2 Street View Panoramas Acquisition . . . . . . . . . . . . . . . . 7 3.2.3 Camera Orientation . . . . . . . . . . . . . . . . . . . . . . . . . 10 3.2.4 Speed Modulation . . . . . . . . . . . . . . . . . . . . . . . . . 15 3.2.5 Preview Video Result . . . . . . . . . . . . . . . . . . . . . . . . 20 3.3 Result Video System . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.3.1 Motion Blur . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.3.2 Final Video Result . . . . . . . . . . . . . . . . . . . . . . . . . 23 4 Performance Evauation 25 5 Conclusion and Future Work 27 5.1 Conclusion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 5.2 Future Work . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 Bibliography 2827369042 bytesapplication/pdf論文公開時間：2014/08/17論文使用權限：同意有償授權(權利金給回饋學校)谷歌街景街景影片旅行預覽旅行回顧thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/261409/1/ntu-103-R01922086-1.pdf
