基于JACK的虚拟人维修动作生成设计

摘要

针对动作仿真软件 JACK 已不能满足虚拟维修训练和仿真需要的问题，设计基于 JACK 软件的虚拟维修动作生成系统。在分析某型防空火箭武器系统维修性的基础上，构建虚拟人维修动作生成系统的基本框架，根据我国国情对JACK软件人体模型的相关参数进行调整，在构建了虚拟人树形分层模型后，对IK算法进行改进，使生成的动作连贯、自然、流畅，并将生成的维修动作转化为JackScript脚本，在JACK仿真软件中进行虚拟人的维修动作仿真。当前这种维修动作生成设计已应用于某型防空火箭武器系统虚拟维修仿真中。%The motion simulation software JACK can’t meet the requirements of virtual maintenance training and simulation, design virtual maintenance motion generation system based on JACK software. Based on analyzing certain type air defense rocket weapon system maintenance, establish basic frame of virtual human maintenance motion generation system. According to domestic situations, debug corresponding parameters of JACK software human model, after establish virtual human tree stratification model, improve IK algorithm to make the motion coherent, natural and fluent. At last change the maintenance motion into JackScript script, simulate virtual human maintenance motion in JACK simulation. The design has been applied into certain type air strike rocket weapon system virtual maintenance simulation.
