摘 要
隨著電腦科學的進步，手繪工程圖數位化處理為目前商業界的主要走向，本論文提出一個工程圖影像之興趣點偵測原型，
利用哈里斯角點偵測(Harris Corners Detector)結構將處理過後的工程圖影像找出工程圖上的角點，並將每一個尋找到的興 趣點做標記跟記錄位置。本論文所使用的前處理有二值化、形態學的膨脹(Dilation)與侵蝕(Erosion)、旋轉(Rotation)、邊緣 檢測，本論文研究將探討前處理後對影像的角點偵測結果與尚未作前處理的影像結果去作分析，並且另外對有執行邊緣檢 測與沒有執行邊緣檢測的結果分別去作比較。本論文研究往後將會應用於商業用途。
關鍵詞 : 哈里斯角點偵測法、二值化、膨脹、侵蝕、旋轉、邊緣檢測 目錄
