http://docs.opencv.org/2.4/doc/tutorials/calib3d/camera_calibration/camera_calibration.html 对于摄像机我们所关心的主要参数为摄像机内参,以及几个畸变系数。上面的连接中后半部分也给了如何标定,然而OpenCV自带的标定程序稍显繁琐。因而在本文中我主推使用MATLAB的工具箱。下面让我们开始标定过程。 标定板 标定的...

Checkerboard patterns are distinct and easy to detect in an image. Not only that, the corners of squares on the checkerboard are ideal for localizing them because they have sharp gradients in two directions. In addition, these corners are also related by the fact that they are at the intersec...
J = (checkerboard(300,4,5)>0.5); figure, imshow(J); 打印完成后,测量实际打印出的网格边长,备用(本人制作的标定板网格边长为 26mm)。将打印纸贴附在硬纸板上(粘贴的尽可能平整),如下图所示。 三、图像采集 运行以下参考程序按q键即可保存图像,注意尽量把镜头的每个方格都覆盖到,最好拍到整张打印纸。
OpenCV3.0 alpha在8月21日发布,其中增加了鱼眼镜头模型,提供了标定、去畸变等一系列api,其实现方法参考了{Camera Calibration Toolbox for Matlab}。本文简单介绍了OpenCV 中实现的鱼眼镜头模型,给出调用demo的关键代码、注释和去畸变的结果。 鱼眼镜头模型

If your calibration board is inaccurate, unmeasured, roughly planar targets (Checkerboard patterns on paper using off-the-shelf printers are the most convenient calibration targets and most of them are not accurate enough.), a method fromstrobl2011iccv can be utilized to dramatically improve the ac...
You can change to calibration flags or parameters as long as you respect the requested format and naming. To run the calibration process, run the program with the following arguments: ./zed_calibration -w=<number_of_corners_in_width_of_checkerboard> -h=<number_of_corners_in_height_of_checke...
