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。
Using gelatin-simulated muscle as a target, orthodromic flash X-rays and a ns-level digital flash X-ray imaging system were used to capture simulated elastomeric gelatin cavities to compensate for the lack of traditional film imaging. On the basis of acquiring the projection images of gelatin cavity, the elliptical approximation of the elastic wound cavity section is established. The non-uniform B-spline surface model of the elastic wound cavity is established, and the control nodes of the non-uniform B-spline surface are extracted. Then, Realistic technology has realized the three-dimensional reconstruction of gelatin bomb wound cavity. It provides a powerful tool and tool for studying the trauma trajectory.
