技術說明

一種基於彈性特徵影像尺的定位量測系統包含：一影像擷取器，對一物件進行多次影像擷取動作；一驅動機構，機械連接至影像擷取器及物件之至少一者或兩者，以造成影像擷取器與物件之相對移動；以及一處理器，電連接至影像擷取器及驅動機構，並執行以下步驟：於控制驅動機構使物件與影像擷取器產生M個相對運動之前與後，控制影像擷取器拍攝物件的N個部分以產生N個影像；及萃取各N個影像的多個特徵點，並分別依據N個影像的相鄰兩者的此等特徵點做跨影像的特徵點匹配，以獲得M個相對運動的資訊，此等特徵點對應於物件特有的表面形貌。 A positioning and measuring system based on a flexible feature image scale comprises: an image capturing device performing image capturing operations on an object; a driving mechanism mechanically connected to one or both of the image capturing device and the object to cause a relative movement between the image capturing device and the object; and a processor electrically connected to the image capturing device and the driving mechanism and performing steps of: controlling the image capturing device to capture N portions of the object to generate N images before and after controlling the driving mechanism to cause M relative movements between the object and the image capturing device; and extracting feature points of each of the N images and performing cross-image feature point matching according to the feature points of neighboring two of the N images to obtain information of the M relative movements, wherein the feature points correspond to unique surface morphology of the object.
