实际上,透镜会有 distortion,一般为 radial distortion 及 tangential distortion,所以 model 需要修改为: k_1, k_2, k_3, k_4, k_5, k_6为 radial distortion coefficients,p_1, p_2为 tangential distortion coefficients。 在OpenCV 所提供的 function - calibrateCamera() 中,distortion coefficients 的排...

Then, based on the radial distortion of the division model, the camera intrinsic parameters and distortion coefficients are solved in a linear way independently. Finally, the intrinsic parameters of the camera are optimized via the Levenberg-Marquardt algorithm. In the proposed method, the distortion...
Camera parameters include intrinsics, extrinsics, and distortion coefficients. To estimate the camera parameters, you need to have 3-D world points and their corresponding 2-D image points. You can get these correspondences using multiple images of a calibration pattern, such as a checkerboard. ...
k4, k5, and k6 are enabled. To provide the backward compatibility, this extra flag should be explicitly specified to make the calibration function use the rational model and return 8 coefficients. If the flag is not set, the function computes and returns only 5 distortion coefficients. ...
其中k1k1,k2k2是径向畸变系数(coefficients of the radial distortion)。 像素坐标表示为: u¯=u+(u−u0)[k1(x2+y2)+k2(x2+y2)2]u¯=u+(u−u0)[k1(x2+y2)+k2(x2+y2)2] v¯=v+(v−v0)[k1(x2+y2)+k2(x2+y2)2]v¯=v+(v−v0)[k1(x2+y2)+k2(x2+y2)2...
