Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSK, D, xi, R
FUNCTIONomnidir_initUndistortRectifyMap
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Computes undistortion and rectification maps for omnidirectional camera image transform by a rotation R. It output two maps that are used for cv::remap(). If D is empty then zero distortion is used, if R or P is empty then identity matrices are used.

omnidir_initUndistortRectifyMap(K: Mat, D: Mat, xi: Mat, R: Mat, P: Mat, size: Size, m1type: number, map1: Mat, map2: Mat, flags: number): void;
K

Camera matrix K = \vecthreethree{f_x}{s}{c_x}{0}{f_y}{c_y}{0}{0}{_1}, with depth CV_32F or CV_64F

D

Input vector of distortion coefficients (k_1, k_2, p_1, p_2), with depth CV_32F or CV_64F

xi

The parameter xi for CMei's model

R

Rotation transform between the original and object space : 3x3 1-channel, or vector: 3x1/1x3, with depth CV_32F or CV_64F

P

New camera matrix (3x3) or new projection matrix (3x4)

size

Undistorted image size.

m1type

Type of the first output map that can be CV_32FC1 or CV_16SC2 . See convertMaps() for details.

map1

Output destination, filled by the native operation. The first output map.

map2

Output destination, filled by the native operation. The second output map.

flags

Flags indicates the rectification type, RECTIFY_PERSPECTIVE, RECTIFY_CYLINDRICAL, RECTIFY_LONGLATI and RECTIFY_STEREOGRAPHIC are supported.
