摘　　要：为了提升受训人员的沉浸感与真实感,以虚拟现实技术为主要手段,面向警务实战训练,提出虚拟动态场景构建方法。采用三角剖分算法得到场景中物体离散点的拓扑关系,根据构建的顶面模型顶点与立面,架构出警务实战训练虚拟现实场景中的所有物体。融合动态规划与泊松图像编辑方法,由最佳拼接位置处去除场景的整合痕迹。针对警务实战训练虚拟现实场景的动态特征,利用虚拟现实模型语言设计插补组件,实现物体的动态变化功能,依据连续两帧影像间的内在射影关系,消除场景内的不良像素点。实验结果表明,所提方法构建的动态场景具有较强的沉浸感与真实感,且动态场景影像数据更新具有实时性特点。Taking virtual reality technology as the main means of actual police actual combat training,this paper puts forward a method for constructing virtual dynamic scenes.At first,the triangulation algorithm was adopted to obtain the topological relationship among discrete points of objects in the scene.Based on the vertices and fagades of the top surface model,all objects in the virtual reality scene of police actual combat training were constructed.And then,dynamic programming was combined with the Poisson image edition,and the integrated mark of the scene was removed from the best splicing position.According to the dynamic characteristics of the virtual reality scene,the virtual reality model language was used to design the interpolation component and thus to realize the dynamic change of the object.Finally,the bad pixels in the scene were eliminated through the internal projective relationship between two consecutive images.Experimental results show that the dynamic scene constructed by the proposed method has strong immersion and realism.And the image data of dynamic scenes can update in real-time.
