摘要
工业CT图像三维可视化能够对工业构件提供真实、直观的反映。体绘制技术可以显示工业CT三维数据的整体特征和内部细节信息。根据光线投射算法的特点,采用对原始数据场进行最大熵原则的预处理的方法,加快了绘制速度,在一定程度上改进了光线投射算法,取得了较好的显示效果。
Three-dimensional visualization of ICT image gives a real and intuitionistic image of industrial components. It can display the whole characteristics and inner detail information of ICT 3D data by volume rendering. Based on the characteristics of volume rendering, maximum entropy was introduced to original data field applying for image preprocessing, accelerating the speed of protract, improving the ray casting in a certain extent. The results of reconstruction are satisfactory.
