This article discusses the stm hardware design first , and increase the scanning accuracy with the outside clock ; add supervise and control , increase to the scanning speed with the accuracy on the run software ; to handle the image in 2d and 3d space of stm 本論文首先討論stm的硬件設計,增加外設時鐘,提高掃描精度;在執(zhí)行軟件上面增加狀態(tài)監(jiān)控,提高掃描速度和精度;然后討論stm圖像在二維和三維空間上的處理與重建。
