VR Panoramic Video Production Software Object Visualization 3D Virtual Simulation

VR全景视频图像边缘像素点灰度值差异性较大,图像目标点关联性差,提出VR全景视频制作软件目标可视化三维虚拟方法。利用柱面模型生成全景视频图像,利用Canny算子计算出图像的边缘信息并对其进行角点匹配,完成全景视频拼接。对拼接后的视频采取反投影,实现VR全景视频软件制作。对三维空间内的目标进行定位,使用射线的投影矩阵和图像点的匹配关联,构建新的空间点坐标方位,得到最终的投影矩阵,完成目标在三维虚拟空间内的可视化虚拟。仿真结果证明,研究方法具有更高的图像目标匹配率,且目标个体位置虚拟精度更高,可广泛应用于实际场景中。

Due to great difference of gray values of pixels on the edge of VR panoramic video image and low rele⁃vance between image targets,this paper presented a 3D virtual method of object visualization of VR panoramic video production software.Firstly,the cylinder model was used to generate the panoramic image,and then Canny operator was adopted to calculate the edge information of image and match its corners,and thus to complete panoramic video mosaics.The back projection was adopted for the video after splicing to achieve VR panoramic video software produc⁃tion.In order to locate the target in 3D space,the projection matrix of ray and the matching relation of image points were used to construct the coordinates of new space points,and thus to get final projection matrix.Finally,the virtual reality of target in 3d virtual space was achieved.Simulation results show that the proposed method has higher matc⁃hing rate of image targets and higher virtual precision of individual position.
