用於路線規劃的整合式平滑谷歌街景影片與地圖

在使用電子地圖規劃路線時，經常會有只能看到路線走法與道路名稱，而對於實際上依照路線行進時的景色不甚了解，因而不能依規劃的路線正確行進的情況。在這篇論文中，我們提出一個系統可以接受使用者輸入路線的起點與終點，該系統便會自動連線到Google，並藉由Google Map的路線規劃與Google Street View的景色，輸出從該路線起點到終點的流暢影片。配合Google Map的即時地圖對應，使用者便可以了解在路線中行進到不同位置時的不同景色，也可以如同坐在車上一般順暢的瀏覽整個路線。這個系統的過程為全自動的，並且憑藉著目前較易取得的Google Street View圖片，配合Image Alignment與Poisson Blending，便可以將路線上每一張圖片串成連續的影片，進而輸出視覺上近似真實的效果。當結果影片輸出之後，使用者可以讓系統從頭到尾自動播放，也可以自由拖曳影片以決定想看的部分及播放的速度。當需要仔細觀察周遭景色時，也可以將目前所在位置的全景圖另外再開一個視窗，在該視窗中使用者可以用滑鼠控制想要觀察的方向。

While planning route with electronic maps, we often only know about driving direction and the name of the streets, but we could not know the scenery along the route. Thus, it is sometimes hard for us to drive through the planned route in reality. In this thesis, we provide a system that takes start and end point as input, and it will automatically connect to Google Map and Google Street View, downloading route information and scenery along the route. Finally it will generate smooth scenic video from starting point to destination, which combines maps to provide better route recognition. Users can watch the video as if they are driving a car through the planned route. Our system is fully automatic, downloading panoramas from Google Street View and combines each picture with image alignment and blending technique to create a continuous video, with visually real quality. With the output video, user can let the system play the video from start to end, or user can browse the video with slider to choose which part he wants to see and adjusts playing speed. When user feels the need to see the scene around him, he can open up another window with panorama image of current position, and he can view the scene with mouse.
