【摘要】 直观岩土CT图像分析是最基本的CT分析方法,而高分辨率的岩土CT图像是这一分析方法的关键。为了提高岩土CT图像的分辨率,根据人眼的视觉特点,结合计算机数字图像颜色模式和图像格式,采用灰度级-彩色变换方法,对灰度CT图像进行伪彩色增强,显著地提高了CT图像的分辨率。更多还原

【Abstract】 As a non-destructive and non-invasive technique,CT technique has been successfully used to detect internal fracturing process of soil and rock. In previous geotechnical CT image analysis,CT data are transformed into gray-scale images as usual. However,it is well known that human vision is less sensitive to difference between gray-scale pixels than that between color ones,so the detailed distribution of CT number is not easily recognized based on gray-scale CT images. In order to improve the discriminability,a pseudo color enhancement method based on gray-scale-color transform is used for geotechnical CT image,and some of gray-scale CT images are enhanced using this method. It clearly shows that the enhanced CT images can be more easily discriminated than gray-scale ones.更多还原
