Abstract: 本論文研製之監控影像資料庫中針對前景物的搜尋方法,以蒙恬公司所提供的監控影像追蹤技術為基礎,分析物體在不同情況下的移動狀態並做相關處理,將代表前景物的外接矩形(Bounding Box)依時間順序建構出移動軌跡,作為監控影像資料庫的索引。而在搜尋介面上,由於傳統文字介面的查詢對於使用者而言,比較無法直觀找出所需要的資訊,因此我們採用友善的圖形化搜尋介面,讓使用者直接就可在畫面上輸入所欲搜尋物體之移動軌跡,經過與已建構的資料庫索引比對後,即可找到最相似的所需內容,讓使用者操作非常方便而更容易上手。
The thesis focuses on a searching method of foreground in a surveillance video database. We base on the tracking technology of PanPower Corp. and analyze moving states of objects to set up their trajectories which become the indexes of the surveillance video database. The trajectories are composed of a lot of bounding boxes which are arranged in a time sequence. The interface of the surveillance video database provides users to enter a trajectory of target object and compares it with indexes which have been set up before to find the most precise result. The design of interface is friendly to users and better than a traditional text interface.
