一種三維資料擷取方法,適於擷取受測物體的三維資料,包括下列步驟。首先,將雷射光投射於受測物體之表面上的多個區域,以在每一所述區域分別產生多個特徵點。接著,針對每一所述區域,同步自第一方向以及第二方向擷取受測物體與所述特徵點,以產生對應於第一方向的第一物體影像以及對應於第二方向的第二物體影像,再將第一物體影像以及第二物體影像進行處理,以取得第一物體影像以及第二物體影像中所述特徵點的二維座標。之後,根據每一所述區域所對應的第一物體影像以及第二物體影像中所述特徵點的二維座標,獲得受測物體的三維資料。 A method for three-dimensional data acquisition, adapted to acquiring three-dimensional data of an object, includes the following steps. First, a laser light is projected onto a plurality of regions on the surface of the object so as to form a plurality of features within each of the regions. For each of the regions, the object and the features are captured from a first direction and a second direction so as to generate a first object image corresponding to the first direction and the second object image corresponding to the second direction. For each of the regions, the first object image and the second object image are processed so as to obtain the two-dimensional coordinates of the features. Next, the three-dimensional data of the object is obtained according to the features in the first object image and the second object image corresponding to each of the regions.
