摘要
传统城市街区建筑三维重建技术对建筑物数据的采集存在误差和噪声,导致重建结果不准确,干扰纹理明显。提出新的智慧城市街区虚拟全景影像三维快速重建技术。确定城市街区建筑物坐标,预处理车载激光雷达设备采集到的建筑物数据,提取建筑物数据特征。将街区所有建筑物在计算机上编写成DXF文件,将其导入VisuaISFM三维重建软件中,重建街区三维虚拟影像。进行仿真对比三组技术的重建误差、和收敛性能。实验结果表明,所提的智慧城市街区虚拟全景影像重建技术具有更低的重建误差,收敛性能较为理想。
The traditional three-dimensional reconstruction technology of urban block has the defects of inaccurate reconstruction results and obvious interference with texture.Therefore,a new 3D fast reconstruction technology of virtual panoramic image of smart city block is proposed in this paper.Building coordinates of urban blocks were determined to process building data collected by vehicle borne lidar equipment,thus the building data features were extracted.All the buildings in the block were written into DXF files on the computer.The generated files were imported into VisuaISFM software to reconstruct the 3D virtual image of the block.Through the design of simulation experiments,the reconstruction error and convergence performance of the proposed method were compared with those of the two traditional methods.The experimental results show that the proposed method has lower reconstruction error and more excellent convergence performance.
