WebSome cameras have lenses that cause a little distortion to the image, and for this purpose OpenCV offers methods to aid in the camera calibration process. 实际上，如果您想编写一个可以自动校正图像失真的应用程序，首先，您需要发现需要哪些神奇的值用于撤消此效果.这些值来自正确的校准程序. WebWhile the distortion coefficients are the same regardless of the camera resolutions used, these should be scaled along with the current resolution from the calibrated resolution. The process of determining these two matrices is the calibration. Calculation of these parameters is done through basic geometrical equations.
