【摘要】 由于得到基于误差传播理论的重建不确定性显式公式并没有直观性,文章在给出三维重建扰动分析模型的基础上,应用多元分析的统计方法研究了图像量化误差、匹配误差、标定误差等对重建精度的影响。采用计算机仿真图像进行实验,向重建模型中输入高斯噪声进行扰动分析,这样有利于对不确定性的评定,仿真实验证明了方法的有效性。最后,对三维重建点的伸展不确定性也进行了可视化。更多还原

【Abstract】 Since the explicit uncertainty equation of3D reconstruction achieved by error propagation theory is not intuitionistic,this paper presents a perturbation analysis model of3D reconstruction and studies reconstruction precision affected by image digitalization error,matching error and calibration error using multidimensional analysis of statistic method.The authors add the reconstruction model with Gaussian noise for perturbation analysis using synthetic images,thus is helpful for uncertainty evaluation,Experimental results demonstrates the validation of our method.Finally,expanded uncertainty of the reconstructed points is visualized.更多还原
