针对当前方法难以获取3D动画场景完整正确的信息,存在计算复杂、三维动画场景连续性较差的问题,提出基于虚拟现实技术的3D动画场景平面设计方法.该方法先在空间中建立代表动画场景深度信息的网格节点,将摄像机坐标系与世界坐标系的坐标进行变换,得到关于动画场景图像候选网格节点的深度坐标值;利用动画场景的深度图像进行预处理以平滑噪声,获取动画场景图像的三维点云;根据动画场景图像特征点与三维点云之间的关系得到动画场景图像的三维特征点,利用ICP法完成动画场景图像点云的精确配准,由此建立3D动画场景模型.实验结果表明,所提方法能够有效提升3D动画场景的重建精度,且具有较强的实时性及稳定性.%Since it is difficult for the current method to acquire the complete and correct information of the 3D animation scene,and exists the problems of the poor continuity of 3D animation scene and complex computation,a graphic design method of 3D animation scene based on virtual reality technology is proposed. With the method,the grid nodes representing the depth information of animation scene are established in the space coordinates;the camera coordinate system is transformed into the world coordinate system to get the depth coordinate values of the candidate grid nodes of the animation scene;the preprocessing for the depth image of animation scene is used to smooth the noise to acquire the 3D point cloud of the animation scene image. According to the relationship between the feature points of animation scene image and 3D point cloud,the 3D feature point of animation scene image is obtained,and the ICP method is used to realize the point cloud accurate matching of the animation scene image to establish the 3D animation scene model. The experimental results show that the method can improve the recon-struction accuracy of 3D animation scene effectively,and has strong real-time performance and high stability.
