| 中文摘要: |
| 针对常用的金刚石切割线人工检测抽检误检率高，检测精度低，而且由于实际环境中成像条件的限制，图像的背景光照不均匀，金刚石颗粒粘连在一起，给金刚石颗粒提取带来困难的现状。课题组提出了基于机器视觉的非均匀光照金刚石切割线颗粒提取方法，利用同态滤波去除噪声与光照不均匀度，最大间方差法对采集的图像进行二值化处理，引入形态学与分水岭分割融合的算法对粘连颗粒进行分割，根据八连通域标记方法统计出颗粒数。课题组对6种不同样本进行对比试验，结果表明课题组所提出的方法准确度较高，提高了计算速度。 |
| 英文摘要: |
| The commonly used diamond cutting line has a high false detection rate and low detection accuracy. Due to the limitation of imaging conditions in the actual environment, the background illumination of the image is uneven and the particles are stuck together, which brings difficulties to extract diamond particles. In this paper, a non uniform illumination diamond cutting line particle extraction method based on machine vision was proposed. The homomorphic filtering was used to remove noise and illumination unevenness. The OTSU method was used to binarize the acquired image, and the morphological and watershed segmentation fusion were introduced. The algorithm divided the adhesion particles and counted the number of particles according to the eight connected domain labeling method. The comparison experiments on six different samples show that the proposed method has higher accuracy and faster calculation speed. |
