OpenCV在作相机校正时,有考虑到径向(radial)和切向(tangential)两个因素,径向失真会产生桶状或类似鱼眼效果的失真,对于一个校正前的像素点(X,Y),校正后的位置在(Xcorrected,Ycorrected),以下为径向失真校正前后位置的关系: 切向失真主要发生在镜头和拍摄物体面不是平行,由以下的公式进行切向失真校正: 综合以上两个公...
相机标定/校正(Camera Calibration) 以前DIP課程有做過Camera calibration,這次因為用Gopro做Visual SLAM,所以又要撿一下校正的過程。主要還是張正友的方法。 OpenCV: 用OpenCV自帶的Sample:路徑 C:\opencv\sources\samples\cpp\tutorial_code\calib3d\camera_calibration 1)打印自製校正板,用相機從不同角度拍攝(理論上...
接下來,分成三部分介绍:相机內部及外部参数、相机失真参数、OpenCV 校正实例。 內部参数矩阵、外部参数矩阵 Camera Calibration 是利用多个已知 世界坐标 与 其对应的 像素坐标 的特征点,求解 Camera 的 內部参数矩阵 及 外部参数矩阵,其理论基础: 世界坐标(3D) 经过 相机外部参数矩阵的作用转换成 相机坐标(3D),而...
OpenCV版本:3.2.0 摄像头:640×480像素,90度广角镜头 一、标定步骤 1、找到标定例程 进入OpenCV安装目录,找到samples/cpp/tutorial_code/calib3d/camera_calibration目录,把它拷贝到一个合适的位置。(因为可能需要修改一些代码,因此不建议直接在原目录下使用。) ...
target_link_libraries(Camera_Calibration ${OpenCV_LIBS}) 编译 mkdir build cd build cmake .. make 4、运行 运行时需要传入配置文件作为主函数的参数: ./Camera_Calibration ../in_VID5.xml 程序启动后会出现当前摄像头拍摄到的画面,画面里有操作提示。按下键盘'g'键开始标定。请务必使摄像头从不同方向拍...
Note: In OpenCV the camera intrinsic matrix does not have the skew parameter. So the matrix is of the form Different types of camera calibration methods Following are the major types of camera calibration methods: Calibration pattern:When we have complete control over the imaging process, the bes...
Well, I am trying to do camera calibration with opencv 2.4.9 in windows 8.1 operating system (ubuntu operating system doesn't resolve the problem.) Problem: I am using the code below to calibrate my camera, but it seems that if the number of my sample images (with chec...
