摘要
为了能够从不同方位直观真实地观看岩心图像 ,应用计算机处理技术对岩心外表面展开图像进行了三维模拟岩心恢复 .恢复岩心原貌分两个步骤 :一是形状再现 ,即将平面图像转换成圆柱体三维投影图 ;二是光学处理 ,即修正圆柱体三维投影图不同部位的亮度和色彩 ,提高三维模拟岩心的显示效果 .实例显示表明 ,这种恢复的三维模拟岩心能够满足用户要求 .
Three dimensional simulation core restoration is performed on the expanded images of core outside surface so as to observe the image visually and exactly from different directions. The core restoration is divided into two steps:①shape reappearance which includes converting the plane image into cylindrical 3D projective view; ②optical treatment which includes luminance and color calibration on the cylindrical 3D projective view to change the luminance and color at different positions of view , thus generating the true 3D core . Concrete example shows that the restored 3D simulation core could fully meet the requirements of customers.
