cv2.undistortPoints

Raw wrapper of cv2.undistortPoints(src, cameraMatrix, distCoeffs, criteria?). Parameters marked '?' are optional; blank means OpenCV default. See the OpenCV documentation for details.

NameTypeDefaultDescription
srcNPARRAY,IMAGE,MASKObserved point coordinates in **pixel coordinates** of the distorted image, 2xN/Nx2 1-channel or 1xN/Nx1 2-channel (CV_32FC2 or CV_64FC2) (or vector\ ). Accepts a ComfyUI IMAGE/MASK directly (frame 0 of a batch) or an NPARRAY. Arithmetic ops (add, multiply, etc.) process the full IMAGE batch when both inputs have the same batch size.
cameraMatrixNPARRAYCamera matrix $\vecthreethree{f_x}{0}{c_x}{0}{f_y}{c_y}{0}{0}{1}$ . A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here.
distCoeffsNPARRAYInput vector of distortion coefficients $(k_1, k_2, p_1, p_2[, k_3[, k_4, k_5, k_6[, s_1, s_2, s_3, s_4[, \tau_x, \tau_y]]]])$ of 4, 5, 8, 12 or 14 elements. If the vector is NULL/empty, the zero distortion coefficients are assumed. A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here.
criteria_typeoptCOMBOmax count or epsilon (whichever first)When to stop iterating: after max_count iterations, when the change drops below epsilon, or whichever comes first.
criteria_max_countoptINT301–2147483647Maximum iterations (ignored when 'epsilon only').
criteria_epsilonoptFLOAT0.000–1e+38Target accuracy / smallest change worth continuing for (ignored when 'max count only').
