摘要

摘要: 研究陶瓷晶粒尺寸分布对估计陶瓷样品的物理属性具有重要意义, 当前主要依赖人工方法测量晶粒尺寸, 由于晶粒形状不规则且大小不一, 因此人工方法测量效率低、误差大. 针对该问题, 提出一种数据与模型联合驱动的陶瓷材料晶粒分割算法. 该算法首先通过图像预处理解决材料表面反光导致的灰度不均匀问题; 其次利用本文提出的鲁棒分水岭变换实现图像中晶粒的预分割, 解决传统分水岭算法存在的过分割以及分割区域个数与轮廓精度难以平衡的问题; 最后提出轻量级富卷积特征网络输出晶粒轮廓, 并利用该轮廓对预分割结果进行优化. 与主流图像分割算法相比, 该算法一方面利用鲁棒分水岭变换实现了更为准确的晶粒区域定位, 另一方面利用图像的低层与高层特征融合获取了更为精准的晶粒轮廓. 实验结果表明, 该算法不仅能够实现陶瓷材料晶粒尺寸的精准计算, 而且具有较高的计算效率, 为分析陶瓷材料物理属性提供了客观准确的数据.

Abstract: The research of the distribution of ceramic grain sizes is significant for estimating physical properties of ceramic materials. At present, researchers mainly use manual methods to measure ceramic grains, which leads to low efficiency and large error due to the irregular shape and different sizes of grains in ceramic images. To solve this issue, a new algorithm used for grain segmentation of ceramic materials is proposed in this paper. This algorithm first performs image pre-processing to solve the problem of intensity inhomogeneity caused by surface reflection of materials in the imaging process. Secondly, a robust watershed transform (RWT) is presented and used for pre-segmentation of grains in scanning electron microscope images, which solves two problems existing in traditional watershed transform, one is over-segmentation and the other is the difficulty of balancing the number of segmentation regions and the accuracy of boundaries. Finally, we present a lightweight and richer convolutional features network (LRCF) used for grain contour prediction, and use the results generated by LRCF to optimize the pre-segmentation result. Compared with popular image segmentation algorithms, the proposed algorithm shows two advantages. On one hand, it achieves more accurate grain region segmentation due to the employment of RWT; on the other hand, it provides more accurate grain boundaries due to the optimization of LRCF. Experimental results show that the proposed algorithm not only provides accurate grain sizes of ceramic materials, but also shows high calculation efficiency, which is significant for property analysis of ceramic materials.
