摘要：

以一组人体头部层去式实体扫描切片为对象,对数字化人体的三维重建技术进行研究。用基于颜色空间的方法提取目标图像,完成图像去噪和边缘检测工作;并用VC++语言编程调用matlab引擎追踪并记录目标象素的坐标值,获得点云数据文件;在CATIA环境下进行曲面拟合,完成三维数字化实体的重建,并生成可直接可供快速原型机的STL文件。

Abstract: It has been studied how to reconstruct base on the solid sections that come from human head.The target image has been abstracted in accordance with the different color, whose outline has been identified, and whose impurity has been deleted.The points of the outline that will make up the point cloud file have been caught and recorded using VC++ to call the Matlab applications.Three-dimensional digital human body can be reconstructed with the CATIA software, and the point cloud file can be translated to the STL file that can be used in RPM directly.
