| Abstract: | 本論文提出一個以X 光影像三維重建印刷電路板上錫球的三維影像，以利檢測錫球內部瑕疵。在本論文中，我們採用同步代數重建技術與濾波背投影兩種方法來實作並加速執行時間，得出錫球在不同高度上的切面影像，最後將兩者的結果與現今市面上Volume Graphics 的重建軟體之結果作比較。 In our project, we attempt to reconstruct the 3D model of solder balls on the PCB (Printed Circuit Board) according to many projections of X-ray images of those solder balls. We mainly use two methods: SART (Simultaneous Algebraic Reconstruction Technique) and FBP (Filtered Back Projection). Consequentially, we finally obtain the 3D model of those solder balls, which can be used to inspect their inner structure. We also optimize our execution time and compare our result with that of Volume Graphics. |
