本發明係描述一以影像為基礎的量測系統,其係利用數位相機之CCD影像中任意兩參考點之像素值變化,來量測在一傾斜面上之目標物,利用相機沿著拍攝方向的移動距離以及影像中任意兩參考點的像素值變化之間的關係,可以計算出在傾斜面上目標物的拍攝距離及傾斜角度。而將其應用於二維傾斜面之目標物的定位,可以證明本發明之有效性。另外,為了讓常見的變焦數位相機能在本發明中使用,本發明還推導出一公式,用來計算相機的等值移動距離。 This invention describes an image-based system for measuring target objects on an oblique plane based on pixel number variation of CCD images for digital cameras by referencing to two arbitrarily designated points in the image frame. Based on an established relationship between the displacement of the camera movement along the photographing direction and the variation in pixel counts between the reference points in the images, photographic distance and incline angle for objects lying on an oblique plane can be calculated via the proposed method. As an application of the proposed approach, two-dimensional localization of target objects on an oblique plane is also demonstrated to show the effectiveness of the proposed approach. To allow the use of widely available digital zoom cameras for ranging and localization by the proposed method, a parameter equivalent to the displacement due to the camera movement is also investigated and derived in this invention.
