摘要:
对三维重建结果的表面特征进行提取和误差分析,是提高三维目标测量精度的关键步骤. 提出了对三维重建表面几何特征进行提取,并对其进行参数测量计算的方法. 首先利用STL文件对三维重建得到的目标点云数据进行读取、导出并筛选,得到三维重建目标的点云数据,通过迭代计算生成CAD模型表面点云数据. 再提取重建目标与CAD模型的几何特征,计算粗糙度、平行度和平面度等几何参数特征值,进行误差比较和分析,最后将该结果反馈至三维目标重建过程中. 实验结果表明,提出的方法能有效地提取三维重建结果表面几何特征及对表面进行测量计算.
Abstract:
Extraction of surface feature and error analysis is an important step for accurate measurement of three-dimensional(3D) reconstruction. A method for extracting the surface feature and computing the parameter of 3D reconstruction was proposed. Here we used the STL file to extract and import the point cloud data for the 3D reconstructed object, thus we obtained the point cloud data of 3D reconstructed object, and generated point cloud data of the computer aided design CAD model surface by iteration. Then we extracted the geometric features of the reconstructed object and the CAD model, and computed the feature values of geometric parameter such as roughness, parallelism and flatness to compare and analyze the errors. Finally, the result was fed back to the processing of 3D reconstruction.It demonstrates that the proposed algorithm has good effects in extracting surface feature and analyzing the errors of 3D reconstruction.
