摘　　要：三维交互式场景构建精度过低会影响人机交互时的体验效果,为有效提升场景的真实性与场景构建效率,提出三维交互式场景虚拟现实建模方法。从前进后退、左右平移、左右旋转抬头与低头四个角度出发,运用虚拟现实技术对场景构建时用户动作的影响因素展开具体分析;根据分析结果对虚拟交互场景内的相机实施标定处理,通过相机的标定结果获取场景影像,并使用图像分割方法对影像目标实施分割处理;基于影像的目标分割结果结合用户动作影响参数,制定模型约束条件与目标函数,构建三维交互式场景构建模型,通过上述模型实现三维交互式场景的构建。实验结果表明,使用上述方法开展三维交互式场景构建时,场景构建的效果较好,分辨率较高,达到了预期目标。In order to effectively improve the authenticity of the scene and the efficiency of scene construction,a modeling method of virtual reality for 3D interactive scenes was put forward.From multiple angles,the forward and backward,the left and right translation,the left and right rotation,as well as the head raising motion and head-down,VR technology was used to specifically analyze the influencing factors of user actions during scene construction.According to the analysis result,cameras in virtual interactive scenes were calibrated,and then the scene image was obtained.Meanwhile,the image target was segmented by some segmentation methods.Based on the results of target segmentation and the influence parameters of user actions,model constraints and objective functions were set.Furthermore,a model of the three-dimensional interactive scene was constructed.On this basis,the construction of the threedimensional interactive scene was achieved.Experimental results show that the effect of scene construction is better,and the resolution is higher when this method is used to construct 3D interactive scenes.The expected goal is achieved.
