“中国力学虚拟人”骨骼系统仿真平台研究

Research of "China Mechanical Virtual Human" Skeleton System Simulation Platform

在中国可视人冷冻切片图像序列数据集的基础上,首先通过三次有理B样条曲线拟合获得人体头部、颈椎、胸腔、脊柱、上肢、下肢、手部和足部的骨组织曲线曲面模型;然后定义了中国力学虚拟人的整体坐标系统;最后采用opencascade三维建模算法编程实现了中国力学虚拟人骨骼系统的整体重建,开发了中国力学虚拟人骨骼系统仿真平台软件。该平台可以为航空航天、车辆工程、船舶工业、虚拟手术、医学教学、军事训练、人体生物力学研究、虚拟现实等提供精确的人体计算模型。

Based on China Visible Human cryosectional images sequence, first through cubic B-splinefitted curve arithmetic to better approximate the bone structure boundary, the curve and surface models of head, cervical spine, chest, spine, upper limbs, lower limbs, hand and foot skeleton were got. Second the universal coordinate system of China Visible Human was built. Third opencascade 3D modeling arithmetic was utilized to build and integrate models of China Visible Human. In the end, under Microsoft Visual 2005 programming with C＋＋, China Visible Human Skeleton System Simulation Platform software was developed. Through practical test, precise Chinese human body virtual model can be provided for aeronautics, automobile, ship, virtual surgery, medical education, military training, human biomechanics, virtual reality and so on.
