相机校准矩阵捕获在用于成像的相机中发生的3D点到2D图像平面的变换。给定3D空间中精确放置的一些点的世界坐标，相机校准需要测量这些场景点在图像平面上的2D投影。虽然可以精确地测量三维空间中点的坐标，但由于测量噪声的影响，从数字图像中确定的图像坐标并不精确。在本文中，我们推导了由于测量误差而导致的相机内在参数（icp）误差之间的解析关系。结果表明，当测量噪声为高斯噪声时，icp的误差呈高斯分布。我们用实验验证了这些结果。
The camera calibration matrix captures the transformation of a 3D point onto a 2D image plane as occurs in the camera being used for imaging. Given the world coordinates of a number of precisely placed points in a 3D space, camera calibration requires the measurement of the 2D projection of those scene points on the image plane. While the coordinates of the points in 3D space can be measured precisely, the image coordinates that are determined from the digital image are not precise mainly because of the measurement noise. In this paper, we derive analytical relationships between the errors in the intrinsic camera parameters (ICPs) due to error in measurements. We show that the errors in the ICPs are Gaussian distributed when the measurement noise is Gaussian. We verify these results experimentally.
