技術說明

本發明之目的在於應用強健馬爾可夫隨機場動態影像處理技術，試圖完成表面打磨厚度之即時量測與打磨軌跡追蹤。由於打磨中的環境相當惡劣，會造成影像量測上的誤差，所以本發明使用強健馬爾可夫隨機場動態影像處理技術(MRF)演算法則，配合動態影像處理技術，克服惡劣環境及動態影像處理所造成之誤差，以達成精密打磨之目的。 A grinding method includes the steps of: enabling an image-capturing device to capture a set of consecutive images containing a workpiece being ground by a grinding device; enabling an image-processing device to identify the workpiece from the images, to detect a top edge of the identified workpiece from a latest one of the images, to locate a set of image pixels that lie on the top edge of the workpiece, and to determine relative heights of the image pixels; and enabling a controlling device to control grinding operation of the grinding device with reference to the relative heights of the image pixels. A system that performs the grinding method is also disclosed.
