摘要 用明胶模拟肌肉作为标靶,使用正交的闪光X射线和ns级数字化闪光X射线成像系统,拍摄模拟弹创的明胶空腔,以弥补传统的胶片成像之不足。在获取明胶空腔投影图像的基础上,对弹创空腔截面进行椭圆近似,建立了弹创空腔的非均匀B样条曲面模型,提取非均匀B样条曲面控制节点,然后采用OpenGL虚拟现实技术实现了明胶弹创空腔的三维重建。为研究创伤弹道提供了有力的手段和工具。 A 3D reconstruction method was developed using orthogonal flash Xray images of wound ballistics in a gelatin cavity to overcome troditional film imaging disadvantages. The wound cavity images were obtained using a ns grade multidetector flash Xray imaging system. The image was approximated using nonuniform Bspline surfaces with an elliptic approximation to the cavity crosssection. The image processing included abstracting the reference points from the images and use of OpenGL virtual reality technology. The method gives digital and visual 3dimensional cavity images and is a powerful mean for analyzing wound ballistics.
