摘要: 經由量測系統得到的輪廓形貌資訊每一個視角都有其自己的量測誤差。形貌註冊全部視角雖然盡可能的降低各視角間的誤差量,但註冊過程仍會產生計算誤差,導致誤差斷差出現在每一組輪廓形貌資訊與其具有重疊區域的其他輪廓形貌資訊之間。 本研究主要目的為利用三角薄殼有限元素來網格元素化每一組輪廓形貌資訊。為找尋輪廓資訊間的對應關係,判斷與其他組輪廓形貌資訊的重疊區域後,尋找所有網格節點其內插對應點,接著利用原長為零的虛擬彈簧元素連接之,運用彈簧回復力縮減註冊視角間的誤差,並降低對元件外型輪廓的影響,以獲得完整三維模型。
Every single view profile information obtained by measurement system has it's own measurement error. Though executing the range image registration in all view could reduce the errors between every view to the best of it's possible, there are calculational errors made form shape integrated. It causes the erroneous faults occur between every range image and any other range images which overlapping. This paper describes using triangular thin-shell finite elements to mesh every singe view range image. For seeking the corresponding relationship between every single view profile, we determine the overlaps with other range images to find out the all nodes' corresponding points. After that we use the virtual springs which original lengths are zero to connect them, and use the spring's restoring force to minimize the whole error of range images and reduce the influence about object's surface profile to get the whole contours of component.
