In the physical world, the actual location of a thing is the means to finding it. 在物理世界里，事物的實際位置意味著找到它的手段。
A camera with panning, tilting, and zooming capabilities is used as the eye of the small vehicle.A vehicle location estimation method using house corners is proposed first. 我們提出了基於房屋中天花板角落的自動車定位方式，根據天花板角落的線條形成情況我們可以計算自動車在地圖上的實際位置。
While we won't discuss the details, in either case it is still possible to develop a simple algorithm to compute a record's physical location, given its relative record number. 雖然我們不考慮這些細節，但以上兩種情況給定了它的相對記錄編號，開發一種計算記錄物理位置的演算法仍然是可能的。
