在石油地质图象分析和模式识别中,三维物体重建是很重要的研究。该文研究了岩石样本孔隙和颗粒二维图象三维重建的一种新方法。这种方法利用从二维薄片取得的岩相学图象信息,用图象处理理论技术和数学形态学的方法生成了岩石的三维模型,对重建的三维微观结构和实际砂岩的表面细微结构进行了定量比较,比较显示,这种重建方法得到的三维模型孔隙率与原始图象基本一致,其水平面/纵切面/横切面上的颗粒长径分布与实际岩石有较好的相关性。
In petroleum geological image analysis and pattern recognition, three-dimensional object reconstruction is a very important research. In this paper, a new method of three-dimensional reconstruction of two-dimensional images of rock samples and pores is studied. This method uses the petrographic image information obtained from a two-dimensional sheet to generate a three-dimensional model of a rock by using image processing theory and mathematical morphology to reconstruct the surface microstructure of the reconstructed three-dimensional microstructure and the actual sandstone The quantitative comparison shows that the porosity of the three-dimensional model obtained by this reconstruction method is basically the same as that of the original image, and the horizontal length / longitudinal section / cross-section of particles has a good correlation with the actual rock.
