本文提出了一种应用程序,统计预测的准确性,使用给定的2D-3D对应的单图像几何相机校准。从单个图像和3D形状之间的对应关系中导出相机内函数和外函数对于相机的光学系统丢失时的场景分析(例如在交通事故分析中)是重要的。目前还不清楚单图像校准在实践中是否会成功,特别是当2D-3D对应的数量很少时,即使我们可以通过手工劳动分配准确的对应关系。为此,我们使用合成环境进行系统的相机参数精度评估。基于在实验期间观察到的统计数据,我们的应用程序从简单变量(例如,可以给出对应关系的区域)。由于预测过程不依赖于3D形状,因此它在耗时的过程之前提供校准成功的估计,即,三维扫描和二维-三维对应映射。
This paper proposes an application to statistically predict the accuracy of single-image geometric camera calibration that uses given 2D-3D correspondences. Deriving both camera intrinsics and extrinsics from correspondences between a single image and a 3D shape, is important for the scene analysis when the optical system of the camera is lost, such as in the analyses of traffic accidents. It is unclear whether the single-image calibration will be successful in practice, particularly when the number of 2D-3D correspondences is small, even if we could assign accurate correspondences by manual labor. To this end, we perform a systematic evaluation of the camera parameter accuracy using synthetic environments. Based on the statistics observed during the experiments, our application predicts the calibration accuracy from simple variables (e.g., the area that correspondences could be given). Since the prediction process does not rely on 3D shapes, it provides an estimate of the success of the calibration before time-consuming processes, i.e., 3D scanning and 2D-3D correspondence mapping.
