【正文】 基于 VC++的砂輪表面金剛石識別 [摘要 ] 本文提出了一種基于圖像邊緣輪廓檢測的砂輪表面金剛石磨料識別算法。算法程序基于 VC++開發(fā)，調(diào)用 OpenCV 庫進(jìn)行數(shù)字圖像處理，并利用 MFC 庫制作了算法展示界面。算法通過對樣本圖像進(jìn)行灰度轉(zhuǎn)換、閾值變換、中值濾波、邊緣提取、尋找輪廓等步驟，獲得圖像中金剛石磨料部分的輪廓面積以及區(qū)域邊界點。算法檢測性能良好，程序操作演示界面簡潔直觀。 [關(guān)鍵詞 ] 數(shù)字圖像處理；輪廓檢測；金剛石識別；計算機(jī)視覺 Diamond recognition on grinding wheel surface based on Visual C++ abstract In this paper, one kind of diamond recognition algorithm based on the edgedetection of diamond wheel is proposed. The algorithm program is based on VC++ development, and calls the OpenCV library to carry on the digital image processing, using the MFC library to build the algorithm presentation interface. By using gray transformation, threshold transform, median filtering, edge detection and contour search, the Algorithm obtain the diamond parts area and region boundary in the sample image. The results demonstrates the well performing of the algorithm, and the intuition of the interface.
