| 摘要(中) |
透地雷達(Ground Penetrating Radar, GPR)是目前廣被使用的非破壞檢測技術之一，其優點主要為操作容易、施測迅速，同時亦可蒐集儲存大量地底特徵物之資訊。但由於目前透地雷達檢測所得之影像，多數是由經驗豐富之操作人員進行辨識，以減少因人為誤判而造成工程上之困擾，而此因素勢必會降低透地雷達之適用性。 本研究透過MATLAB處理透地雷達檢測所得之影像，經由程式將透地雷達影像進行轉換，並進行影像扣除之處理，藉此方法以降低透地雷達影像在辨識上的難度，並使操作人員能夠較容易的辨識出影像中產生差異的部份。 |

| 摘要(英) | Ground penetration radar, GPR, is one of non-destructive evaluation tools. It has been originally adopted to detect the locations of mines. Now, GPR is widely used to evaluate the completeness of material, especially for those objects which are buried in ground. The signal emitted from GPR will have different speeds while the signal passing through different mediums. The differences of speed are employed to distinguish the medium properties. The returned signal patterns are manually recognized by experienced engineers. The research tries to import the data collected with GPR to analyze with the Matlab® platform. The imported data is analyzed with the differential operator developed in this research. The results demonstrate the proposed algorithm can identify the differences between two scenes collected at different times. The research shows the feasibility and possibility to employ the proposed algorithm to identify the cracks of reinforced concrete structures. | |||
