About the ARToolKit (虛擬擴增實境函式庫)

　　ARToolKit was originally developed by Hirokazu Kato in 1999 and was released by the University of Washington HIT Lab. Currently it is maintained as an opensource project hosted on SourceForge with commercial licenses available from ARToolWorks. ARToolKit is a very widely used tracking library with over 160,000 downloads since 2004

　　ARToolKit is a computer vision tracking library that allows for the creation of augmented reality applications that overlay virtual imagery on the real world. To do this, it uses video tracking capabilities in order to calculate the real camera position and orientation relative to square physical markers in real time. Once the real camera position is known a virtual camera can be positioned at the same point and 3D computer graphics models drawn exactly overlaid on the real marker. So ARToolKit solves two of the key problems in Augmented Reality; viewpoint tracking and virtual object interaction.

　　ARToolKit最初是由Hirokazu Kato 在1999年，並在華盛頓大學HIT 實驗室公佈。目前，它是保持作為一個開源項目在SourceForge (合作式軟件開發管理系統)與商業許可證可從 ARToolWorks。 ARToolKit是一個非常廣泛使用的AR函式庫。自2004年，已超過 160,000下載次數。

　　ARToolKit是電腦視覺函式庫，它可以創造增強實境應用，是以虛擬圖像覆蓋於現實世界。因此，它用視訊的跟踪能力，以便即時的計算出追蹤物體真正的物理資訊。一旦真正的網路攝影機的視角與虛擬的攝影機視角相對應，可以在同一位置點和3D模型計算出完全覆蓋於實際影像的虛擬位置。因此，ARToolKit解決了虛擬擴增實境"視點追踪"和"虛擬對象的交互效果"這兩個關鍵問題。
