摘要(中) |
一般在進行判讀透地雷達圖時,都是由經驗豐富的工程人員利用各種濾波來做研判,通常判讀時常遇到的問題包括,訊號過於複雜、圖像充斥雜訊、人為誤判等,為了克服上述問題。本研究利用統計學司徒基分組公式來處理透地雷達圖像之數值,並將重新分組之數值定義色階,藉此簡化圖像達到透地雷達剖面圖單純化之目的,使判讀工作更方便、迅速、甚至提高精確度,並有利於初學者判讀。同時,本研究比較柔性鋪面道路試體與實際道路之分析結果並探討司徒基公式應用於透地雷達剖面圖的可行性。 |
摘要(英) |
The raw signals of
ground penetration radar may contain complicated information mixing with
noise. Signal processing is therefore very important to successful GPR
applications. The objective of the current study is to simply the
interpretation of GPR signals. The raw signals are first processed based
on the Sturge’s rule such that the gray scales of the pixels are
re-assigned. The resulted GPR map is thus simplified that important
features are easier to be identified. This method is first tested with
the flexible pavement specimen in the laboratory, followed by the field
test on the underground pipelines at the roadside. The results are
analyzed and compared with other signal processing techniques. |
