In a camera arrangement of a computer vision system, camera calibration is effected on-line, i.e. while the camera is involved in a visual task. The calibration is carried out automatically whenever the camera undergoes a series of displacements relative to a fixed scene. The calibration method...

3 Zhengyou Zhang's "a flexible new technique for camera calibration" based on a planar chess board. It is based on constrains on homography. 4个空间:世界,摄像机(镜头所在位置),图像(原点到镜头中心位置距离f),图像仿射空间(最终成像空间),这些空间原点在不同应用场合可以假设重合。
常见的相机标定中,使用的相机多为针孔相机(Pinhole camera),也就是大家熟知的小孔成像理论。将其中涉及的坐标系之间的相互转换抽离出来,即为针孔相机模型的核心。 上图所示的模型即为针孔相机模型,当然现在有很多资料对其进行阐述,我这里挑选另一种便于理解的表达方法。这里为了方便阐述,将像平面和物方点置于光学中心的...
PythonComputerVision-6-CameraCalibration 使用Python及OpenCV实现相机参数标定 一.针孔相机模型原理: 在相机模型中,针孔相机是相对简单而常用的模型。简单的说,针孔相机模型就是把相机简化成小孔成像,如图下图,f标注的距离是焦距。 简单的相机标定原理: 相机标定(Camera Calibration)可以理解为从普通世界坐标系变换到图像...
