摘要
介绍了基于传统的光学投影层析成像技术(Optical Projection Tomography, OPT),采用高动态范围成像算法对光不均匀吸收的玉石内部结构成像,即采集玉石每个1.8°方向上的高动态范围的图像数据,得到200组吸收投影图像数据进行三维结构成像。其无嵌入式呈现出的三维结构图以及其清晰的层析切片结构图大大辅助了市场上人们对玉石内部及其表面质量好坏的判断鉴定,增加了鉴定过程中的准确性、客观性、科学性。
This paper introduces the technology of Optical Projection Tomography(OPT) based on the traditional.The high dynamic range imaging algorithm is adopted to image the internal structure of the jade with non-uniform absorption of light, that is, to collect the image data of the high dynamic range in each 1.8 degree direction of the jade, and to obtain 200 groups of absorption projection image data for three-dimensional structure imaging. Its non-embedded three-dimensional structure diagram and its clear chromatography-slicing structure greatly assist the people on the market to identify the quality of jade inside and its surface, increase the identification process accuracy, objectivity, and scientificity.
