岩石薄片正交偏光图像的颗粒分割方法

A Particles Segmentation Method of Rock Slice Orthogonal Polarization Images

为了解决图像分析技术应用于岩石薄片粒度分析一直受到图像分割效果的制约问题,提高岩石颗粒自动分割的准确性,提出了一种岩石薄片图像颗粒分割的新方法。该技术是以自主研制的图像采集系统为基础,通过序列图像获取、序列图像处理、多分割层叠加、SRM算法分割以及小面积合并处理等实现颗粒分割。实践表明该技术用于碎屑岩薄片粒度分析可以实现90%以上的颗粒准确分割,具有良好的实用性、可靠性和准确性,弥补了普通显微镜在粒度分析中的不足,具有较高的推广价值。

A new particles segmentation method of rock slice images is proposed, in order to solve the problem of mechanical analysis of rock slice has been restricted by the effect of image segmentation, which is a kind of image analysis technique, and improve the accuracy of the rock particles automatic segmentation. The technology basing on self-developed image acquisition system, through capturing the sequence image, processing sequence image, plu- sing multiple segmentation layer, SRM segmentation algorithm, consolidation of small area processing, etc, achieves particle segmentation. The practice shows that the technology used in the mechanical analysis of clastic rock slice, can make the particle segmentation accuracy rate is achieved more than 90 percent, make up for the shortcomings of ordinary microscope in the analysis of particle size, and has high promotion value, with good practi- cability, reliability and accuracy.
