摘要
复杂曲面重构是反向工程的瓶颈,对于医学模型来说这一问题尤其突出,针对这一问题提出了一种基于CT图像的,以RE/RP直接集成技术为核心的医学模型的快速原型开发方法。在本方法中对扫描得到的CT切片数据直接进行切片处理,根据截面切点数据进行轮廓的识别与提取,获得实体的截面轮廓信息,输出STL格式文件给快速成型系统制造实体的物理原型件,从而避免曲面重构。
The reconstruction to complicated curved surface is the bottleneck of reverse engineering, and it is a special problem for medical model. In order to enhance production s performance and reduce the development time, aiming at the key technologies of 3D reconstruction to medical CT images, a novel procedure for the direct integration was proposed. The contour data are measured by CT and are directly inputted to RP machine for manufacturing only through some simple processing. The method avoids the intermedia...
